| DuPont™ Vamac® DP is an ethylene acrylic dipolymer elastomer. Its general performance characteristics are similar to those of the Vamac® terpolymers, including: Good oil and chemical resistance; High-temperature resistance; Good compression set resistance; and Good low-temperature flexibility Unlike Vamac® terpolymers, Vamac® DP dipolymer can be processed without using a post cure. Typical density for Vamac ® DP is 1.04 g/cc.&& |
