Ethylene/Acrylic Elastomers - New Candidates for Sealing Applications

Ethylene/acrylic elastomers are new candidate materials for challenging automotive sealing problem areas. They promise attractive blends of thermal stability, oil and weather resistance, mechanical properties and low temperature performance for service formerly restricted to the more expensive high temperature silicone and fluorocarbon elastomers. Our preliminary research and development on specific automotive sealing applications has produced data that enables us to position ethylene/acrylic elastomers in relationship with the other commercial seal materials. Revealed are the results of our chemical, material and ongoing field testing programs which are helping us predict the future of ethylene/acrylic elastomers as viable solutions to critical sealing problems.
