On the Rise: Engine Temperatures and Silicone Rubber Properties

This paper shows that the rise in engine temperatures of automobiles has created a need for elastomers which can resist the deleterious effects of the higher heat. In addition to the high temperature requirement, a material with high tear and high modulus was also needed, as it is anticipated that there will be an increased use of silicone rubber fabricated parts. It is also pointed out that silicones have continued to improve their physical properties so that they are now being used in many automotive applications, and will be the answer to many design problems confronting the industry today. It is further predicted that there will be a need of silicone rubber adhesive/sealants to replace preformed gaskets and as bonding agents for trim and automotive ornaments.
