Oil-Resistant Rubbers
improved performance in this area, the gain is usually at the expense of oil and solvent resistance. As with SBR, this material does not crystallize on stretching, and reinforcing materials are required to obtain high strength. With compounding, nitrile rubbers can provide a good balance of low creep

Polyimide
temperature for interrmittent exposure can range from cryogenic to as high as 900 F. Glass-fiber reinforced versions retain over 70% of their flexural strength and modulus at 480 F. Creep is almost nonexistent, even at high temperatures and deformation at under load (4,000 psi) is less than 0.05% at room

Acetal
: Acetal copolymers have high tensile and flexural strength, fatigue resistance, and hardness. Lubricity is excellent. They retain much of their toughness through a broad temperature range and are among the most creep resistant of the crystalline thermoplastics. Moisture absorption is low, permitting
