Aurum® - PI - Polyimide          PI          

Torlon® - PAI - Polyamidimide            PAI

Aurum®, originally developed by NASA, is a relatively new member of the high performance plastics family. Aurum is the finest injection moldable, bearing material available in the general market today. Aurum has 600 degree F capabilities, and high load/low friction properties not duplicated with other injection moldable materials.
Aurum has high viscosity and requires higher performance injection molding machines to mold it properly. The best properties are achieved by processing at elevated melt and mold temperatures.

Torlon is an early member of the high performance plastics family. Torlon® is a high strength, high temperature (500 degrees F max) polymer that is injection, and over "cured" to produce a thermosett polymer. Torlon® has the highest tensile strength of all non-filled, injection moldable materials.

Torlon is recognized as an outstanding bearing material due to low friction/wear, and high compressive strength.

TECHNICAL DESCRIPTION

Torlon® is a high performance amorphous (non-crystalline) engineering thermoplastic. Chemically, Torlon® is a polyamide-imide (PAI), a reaction product of trimellitic anhydride and aromatic diamines. It is called amide-imide because the polymer chain comprises amide linkages alternative with imide linkages. The combination of aromatic groups and imide linkages are responsible for the polymer's exceptional thermal stability. The amide groups impart flexibility and elongation, which results in an engineering plastic with exceptional toughness.

GENERAL PROPERTIES

Torlon® is the highest performing melt processable plastic. It has superior resistance to elevated temperatures. It is capable of performing under severe stress conditions at continuous temperatures to 500°F (260°C). Parts machined from Torlon® provide greater compressive strength and higher impact resistance than most advanced engineering plastics. Its extremely low coefficient of linear thermal expansion and high creep resistance deliver excellent dimensional stability over its entire use range. Torlon® is an amorphous material with a Tg (glass transition temperature) of 537°F (280°C).

TORLON ® GRADES

Torlon ® 4203
Torlon ® 4203 extruded PAI offers excellent compressive strength and the highest elongation of the Torlon ® grades. It also provides electrical insulation and exceptional impact strength. This grade is commonly used for electrical connectors and insulators due to its high dielectric strength.

Torlon ® 4301
Torlon ® 4301 extruded PAI is primarily used for wear and friction parts. It offers a very low expansion rate, low coefficient of friction and exhibits little or no slip-stick in use. Torlon ® 4301's flexural modulus of 1,000,000 psi is higher than most other advanced engineering plastics. This grade excels in severe service wear applications such as non- lubricated bearings, seals, bearing cages and reciprocating compressor parts.

Torlon ® 5530
Torlon ® 5530 is 30% glass reinforced, compression molded PAI. It is ideal for higher load structural or electronic applications. This grade is similar in composition to Torlon ® 5030 PAI (injection molded). It is selected for larger shapes or when the greatest degree of dimensional control is required. Applications include burn-in sockets, gears, valve plates, impellers, rotors, terminal strips, and insulators.

 Rulon ® is the Saint Gobain Performance Plastics trade name for a family of reinforced proprietary PTFE compounds

GENERAL DESCRIPTION

This unique family of materials offers the combination of high compressive strengths, low coefficient of friction, and excellent abrasion and corrosion resistance while running without lubrication. These materials are used in bearing and seal applications at temperature extremes from -400°F to 500°F (-240°C to 260°C) with or without additional lubricants. Rulon ® materials also have the unique property of no "slip stick" --- no erratic motion at low speeds.

RULON ® GRADES

Rulon ® LR

The best known, most widely used Rulon  formulation. Rulon ® LR has a long reputation for high wear resistance, low friction, good electrical properties and chemical inertness. Not only does it make a great sleeve, flange or thrust bearing, it can also be bonded to nearly any surface to provide wear resistance and reduce friction.

Rulon ® J

This is the best Rulon grade for aluminum and soft mating surfaces. Rulon ® J provides the lowest coefficient of friction of all Rulons, and provides good wear and abrasion resistance. Because this grade is "all plastic", it can be run on non-ferrous and non-metallic mating surfaces such as 316 Stainless, brass, and other plastics. It is used in both bearing and seal applications, but is generally not suitable for use in alkaline or oxidizing acid solutions.

Rulon ® 641

This FDA compliant material was specifically developed for food and drug applications. Rulon ® 641 is designed to run dry without any moisture or lubrication.

Rulon ® AR

This was the first commercially available reinforced PTFE and is still quite popular. Rulon ® AR offers the best combination of flexibility and load-carrying properties. It has high wear resistance, low friction, and good electrically insulative and chemical properties. Since,  its fillers are ceramic in nature, mating surfaces should be RC35 or harder. It is and used in seals, piston cups, and some bearings.

Rulon ® 142

A material for extremely heavy loads. Rulon ® 142 is ideal for linear bearing applications such as slide ways in machine tools and heavy equipment, and may also be used in expansion joints and bridge pads. This material provides low friction, excellent unlubricated wear properties and good heat dissipation and is etched one side for adhesive bonding to the steel substrate. Rulon ® 142 competes with Busak+Shamban's Turcite ® B Slide way ® product.

Rulon ® 123

This FDA compliant material is excellent for wet or submerged applications. Rulon ® 123 provides excellent service against soft and non-ferrous mating surfaces.

PPS, polyphenylene sulfide (Ryton® by Chevron Philips Chemical Company, Fortron® by Ticona) is the oldest material in the high performance, injection-moldable category.

Non-filled grades are used exclusively as coatings. With the addition of glass and carbon fibers, minerals, and PTFE fillers, PPS becomes a very suitable molding material. Initially, PPS was promoted as a replacement for thermosetting materials.

While no known solvents attack PPS, strong reducing agents will attack the material, and high temperature water will act as a solvent on the binder which bonds glass-fiber to the polymer (some grades).

PPS is generally used in applications where high temperature and chemical resistance are required. A continuous use temperature of 428 degrees F and short term properties at 500 degrees F allow PPS to be used in automotive, electronic (solderability), and may OEM applications.

GENERAL PROPERTIES

PolyPhenylene Sulfide (PPS) offers the broadest resistance to chemicals of any advanced engineering plastic. They have no known solvents below 392°F (200°C) and are inert to steam, strong bases, fuels and acids. Minimal moisture absorption and a very low coefficient of linear thermal expansion, combined with stress-relieving manufacturing, make PPS ideally suited for precise tolerance machined components.

PPS GRADES

40% Glass Reinforced PPS

This product is the most recognized filled grade of PPS. It offers better dimensional stability and thermal performance than unfilled Techtron ® PPS and maintains its strength to above 425°F (220°C).

Bearing Grade PPS

Bearing grade PPS is internally lubricated and carbon fiber reinforced offering a low coefficient of thermal expansion and uncompromised chemical resistance. It is well suited for thrust or wear applications or when an electrically conductive material is required.
