Virgin TFE

Teflon® PTFE

Teflon® is a plastic that offers high chemical resistance, low and high temperature capability, resistance to weathering, a low coefficient of friction, and electrical and thermal insulation.


Teflon® mechanical properties are low compared to other plastics, but its properties remain at a useful level over a wide temperature range of of -100°F to +500°F (-73°C to 260°C). Mechanical properties are often enhanced by adding fillers (see paragraph below). It has excellent thermal and electrical insulation properties and a low coefficient of friction. PTFE is very dense and cannot be melt processed -- it must be compressed and sintered to form useful shapes.


PTFE's mechanical properties can be enhanced by adding fillers such as glass fibers, carbon, graphite, molybdenum disulphide, and bronze. Generally, filled PTFE's maintain their excellent chemical and high temperature characteristics, while fillers improve mechanical strength, stability, and wear resistance.

Acetal/Delrin DuPont



Acetal is the common name for a family of thermoplastics with the chemical name "PolyOxy-Methylene". Acetal is available in a general purpose copolymer grade, a homopolymer version (Delrin®), and several filled Delrin® grades. Acetal provides high strength and stiffness, enhanced dimensional stability, and is easy to machine. As a semi-crystalline material, acetal is characterized by a low coefficient of friction and good wear properties.


*High strength, stiffness, dimensional stability
*Very low moisture absorption
*Good wear and abrasion resistance
*Wide range chemical resistance (including many solvents)



The copolymer grade offers excellent performance at a slightly lower cost than Delrin®. Acetal copolymer may exhibit center line porosity, but porosity-free material is available. Certain grades are FDA, USDA, NSF, Canada AG and 3-A Dairy compliant. Low stress levels and high strength assure flatness and dimensional stability up to a maximum continuous service temperature of 180°F (80°C). Acetal copolymers are available in a wide variety of colors, including RED, ORANGE, YELLOW, GREEN, BLUE, VIOLET, BLACK, WHITE & NATURAL.

DELRIN® (unfilled)

Delrin® acetal homopolymer offers slightly higher mechanical properties than acetal copolymer, but may contain a low density center (also known as "center line porosity") especially in large cross-sections. The homopolymer also gives slightly less chemical resistance than copolymer acetal. For example, Delrin® is ideal for small diameter, thin-walled bushings that benefit from the additional strength and rigidity of homopolymer acetal. Delrin® is available in BLACK & NATURAL colors.

DELRIN® AF (PTFE-filled)

This material is manufactured from Delrin® homopolymer resin which has been uniformly filled with a dispersion of PTFE (Teflon®) fibers. Delrin® AF is a unique thermoplastic material for use in moving parts in which low friction and long wear life are important. It retains 90% of the mechanical strength of unfilled acetal homopolymer, while offering very low friction and almost no "slip-stick" behavior. Delrin® AF is BROWN in color.

Nylon is one of the most widely used plastics in the world, especially as a bearing and wear material. Nylons are frequently used as replacements for bronze, brass, aluminum, steel and other metals, as well as other plastics, wood, and rubber. 

Nylons offer extremely good wear resistance, coupled with high tensile strength and modulus of elasticity. They also have high impact resistance, a high heat distortion temperature, and resist wear, abrasion, and vibration. In addition, nylons can withstand sustained contact with a wide variety of chemicals, alkalies, dilute acids or oxidizing agents. 

Another important factor, both economically and mechanically, is the relative light weight of nylon -- approximately 1/8 the weight of bronze, 1/7 the weight of cast iron, and 1/2 the weight of aluminum -- which reduces both the inertial and static loads and eases the handling of large components during maintenance or replacement procedures. 


MC®901, MC®907 - Cast Unfilled Nylon 6
Unmodified cast type 6 nylon offers the highest strength and hardness of the nylon 6 grades. MC907, the natural grade (off-white in color), is FDA, USDA and 3A-Dairy compliant and is primarily used for food contact parts.

A heat-stabilized grade, MC901, (Blue in color) offers thermal stability to 260°F, and is used in bearing and structural applications, such as wheels, gears, and custom parts.

Nylatron® GSM - Cast Moly-Filled Nylon 6
Finely divided particles of "Moly" (molybdenum disulfide -- MoS2) are dispersed evenly throughout the nylon material during polymerization. The Moly particles act as a dry lubricant to enhance nylon's load bearing and wear capabilities while maintaining impact strength and toughness. It is most commonly used for gears, sheaves, sprockets and custom parts. It is Dark Grey in color.

Nyloil® - Cast Oil-Filled Nylon 6
Simply put, this is a cast nylon with built-in oil lubrication. During the manufacturing process, oil lubrication is completely and evenly dispersed throughout the cast nylon, making it an integral part of the material's structure that cannot spin out, dry out, or drain out, even under the harshest working conditions. This oil-filler reduces friction by as much as 25% at the bearing interface, and can result in longer wear life than unfilled or moly-filled cast nylons. The standard grade is Green in color, but a natural (off-white) colored FDA & USDA approved grade is also available.

Nylatron® GSM Blue - Cast Moly- & Oil-Filled Nylon 6
This grade combines both molybdenum disulfide (MoS2) and oil for the load capability of Nylatron GSM nylon, plus improved frictional characteristics. It excels in higher pressures and at low speeds. It is Dark Blue-Gray in color.

PEEK can be used continuously to 480°F (250°C) and in hot water or steam without permanent loss in physical properties. For hostile environments, PEEK is a high strength alternative to fluoropolymers. PEEK carries a V-O flammability rating and exhibits very low smoke and toxic gas emission when exposed to flame.

And unfilled PEEK received FDA approval in late 1998!


• Excellent chemical resistance
• Very low moisture absorption
• Inherently good wear and abrasion resistance
• Unaffected by continuous exposure to hot water or steam


PEEK (Unfilled)
This general purpose grade is unreinforced and offers the highest elongation and toughness of all PEEK grades. This material is available in Natural color, but is also available in black. Black PEEK is ideal for instrument components where aesthetics are important, as well as for seal components where ductility and inertness are important. All unfilled PEEK grades comply with FDA regulation 21 CFR 177.2415 for repeated food contact.

PEEK (30% Glass Filled)
The addition of glass fibers significantly reduces the expansion rate and increases the flexural modulus of PEEK. This grade is ideal for structural applications that require improved strength, stiffness, or stability, especially at temperatures above 300°F (150°C). Glass-filled PEEK is light brown in color.

PEEK (30% Carbon Filled)
The addition of carbon fibers enhances the compressive strength and stiffness of PEEK, and dramatically lowers its expansion rate. It offers designers optimum wear resistance and load carrying capability in a PEEK-based product. This grade provides 3½ times higher thermal conductivity than unreinforced PEEK -- dissipating heat from the bearing surface faster. Carbon-filled PEEK is black in color.

PEEK (Bearing Grade)
This grade of PEEK, containing carbon fiber reinforced with graphite and PTFE lubricants, offers the lowest coefficient of friction and the best machinability for all PEEK grades. Bearing grade PEEK has an excellent combination of low friction, low wear, high LPV, low mating part wear, and easy machining. Bearing grade PEEK is black or dark grey in color.

Polyethylene (LDPE, HDPE & UHMW PE)


Polyethylenes are semi-crystalline materials with excellent chemical resistance, good fatigue and wear resistance, and a wide range of properties (due to differences in length of the polymer chain.) Polyethylenes are easy to distinguish from other plastics because they float in water.


Polyethylenes provide good resistance to organic solvents, degreasing agents and electrolytic attack. They have a higher impact strength, but lower working temperatures and tensile strengths than polypropylene. They are light in weight, resistant to staining, and have low moisture absorption rates.


Low Density Polyethylene (LDPE)
This extruded material offers good corrosion resistance and low moisture permeability. It can be used in applications where corrosion resistance is important, but stiffness, high temperatures, and structural strength are not. A highly flexible product, LDPE is used widely in orthopaedic products, or where mobility without stress fatigue is desired. LDPE is also frequently used in consumer packaging, bags, bottles, and liners.

High Density Polyethylene (HDPE)
Representing the largest portion of the polyethylene applications, HDPE offers excellent impact resistance, light weight, low moisture absorption, and high tensile strength. HDPE is also non-toxic and non-staining and meets FDA and USDA certification for food processing.

Ultra High Molecular Weight Polyethylene (UHMW PE)
Light weight (1/8 the weight of mild steel), high in tensile strength, and as simple to machine as wood, UHMW PE is the ideal material for many wear parts in machinery and equipment as well as a superb lining in material handling systems and storage containers. UHMW PE is self-lubricating, shatter resistant, long-wearing, abrasion and corrosion resistant. It meets FDA and USDA acceptance for food and pharmaceutical equipment and is a good performer in applications up to 180 °F (82 °C) or when periodically cleaned with live steam or boiling water to sterilize.



Polypropylene is an economical material that offers a combination of outstanding physical, chemical, mechanical, thermal and electrical properties not found in any other thermoplastic. Compared to low or high density polyethylene, it has a lower impact strength, but superior working temperature and tensile strength.


Polypropylene provides excellent resistance to organic solvents, degreasing agents and electrolytic attack. It has a lower impact strength, but its working temperatures and tensile strength are superior to low or high density polyethylene. It is light in weight, resistant to staining, and has a low moisture absorption rate. This is a tough, heat-resistant, semi-rigid material, ideal for the transfer of hot liquids or gases.

Ultem® is also inherently flame resistant and low smoke generating. It excels in medical reusable applications requiring repeated sterilization and is available in FDA compliant colors.


Ultem® 1000 - unfilled
Unfilled Ultem® excels in hot air and water environments. It's hydrolitically stable -- it retains 85% of tensile strength after 10,000 hour boiling water immersion and 100% of tensile strength after 2,000 steam autoclave cycles at 270°F. It is also UV and gamma radiation resistant.

Ultem® 2100 - 10% glass filled
Ultem® 2200 - 20% glass filled
Ultem® 2300 - 30% glass filled

Glass reinforced Ultem® provides even greater rigidity and dimensional stability while maintaining many of the useful characteristics of basic Ultem®. The glass reinforcement yields a product with an exceptional strength-to-weight ratio and increased tensile strength.

Vespel® SP-1
Vespel® SP-1 is the unfilled base resin grade. SP-1 provides maximum physical strength, elongation, and toughness as well as the best electrical and thermal insulation values. Typical applications include spacers, high-temp fixtures, valve seats, balls, gaskets, insulators, and seals.

Vespel® SP-21
Vespel® SP-21 has 15% graphite by weight added to the base resin for increased wear resistance and reduced friction in applications such as bearings, thrust washers, bushings, seal rings, slide blocks and other wear applications. SP-21 has the highest mechanical properties of the graphite filled grades.

Vespel® SP-22
Vespel® SP-22 has 40% graphite by weight for enhanced wear resistance, lower friction, improved dimensional stability (low coefficient of thermal expansion), and stability against oxidation. Typical uses are the same as those for SP-21.

Vespel® SP-211
Vespel® SP-211 has 10% Teflon® PTFE and 15% graphite by weight added to the base resin for the lowest coefficient of friction over a wide range of operating conditions. It also has excellent wear resistance up to 300°F (149°C). Typical applications include sliding or linear bearings as well as many wear and friction uses listed above.

Vespel® SP-3
Vespel® SP-3 is 15% moly-filled (molybdenum disulfide solid lubricant) for wear and friction resistance in vacuum and other moisture-free environments where graphite actually becomes abrasive. Typical applications include seals, bushings, bearings, gears, and other wear surfaces in outer space, ultra-high vacuum or dry gas applications.
