General Info

Torlon ® 4301 extruded PAI is ideal for challenging wear and friction parts. It offers a very low expansion rate with a CLTE close to many metals, low friction coefficient, and exhibits little or no slip-stick in use. Torlon ® 4301's flexural modulus of 1,000,000 psi is higher than most advanced engineering plastics. This grade excels in severe service wear applications such as non-lubricated bearings, seals, bushings, bearings, thrust washers, bearing cages, and reciprocating compressor parts. It offers ten times more wear resistance than non-reinforced Torlon 4203.

Typical Specifications (Note: For reference only as specifications change. Please verify with Boedeker before your order to confirm specifications)

ASTM 5204 PAI022L15 which replaces Mil-P 46179A Type II, Class 1.	ASTMD7292 PAI0121	AMS 3670/3B	HS MS29.04-02, Form 2, Grade 1 and/or 2.
Honeywell MCS7004, Type 2	BPS 4487	BMS8-269C, Class 2, Grade 12

Key Properties

Maintains strength and stiffness to 500°F (260°C)
Minimal expansion rate to 500°F (260°C)
Excellent wear resistance in bearing grades
Able to endure harsh thermal, chemical and stress conditions

Limitations

Torlon® PAI has a relatively high moisture absorption rate, parts used in high temperatureservice or made to tight tolerances should be kept dry prior to installation. Thermal shock resulting indeformation can occur if moisture laden parts are rapidly exposed to temperatures above 400°F (205° C).

Applications

Bearing Cages
High Temp Bushings & Bearings
Reciprocating Compressor Components
Seals

Manufacturer Trade Names

Duratron®

Boedeker Plastics, Inc. stocks & supplies plastic sheet, rod, tube, film and custom profiles and machine parts from these shapes that are produced from plastic resin. In many cases the manufacturer of the shape has their own product trade name. If your specification calls for a specific resin grade or manufacturer trade name, we can supply a shape made from that resin to meet your specification or suggest an equal. If you require a specific resin or brand it must be specified at the time of order.
