Material Notes:
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 resistanceHigh temperature resistanceGood compression set resistanceGood low temperature flexibilityUnlike Vamac® terpolymers, Vamac® DP dipolymer can be processed without a post cure.Form: Bale size is nominally:560 mm x 370 mm by 165 mmInformation provided by DuPont.
