Advances with high Temperature Resistant ACM Elastomers

摘要

With the trend to ever decreasing space in the engine bay,temperatures continue to rise,placing ever more demanding requirements on the components operating in this environment.One consequence of this is the need for Elastomers capable of ever-greater long-term high temperature resistance.Higher operating temperatures has also resulted in the development of more aggressive automotive fluids and lubricants,further necessitating the use of specialty elastomers combining both greater heat and fluid resistance.This paper will describe the advances made and latesj developments with long-term high temperature resistant ACM elastomers and associated materials.These materials are designed to provide both functional performance and processability in a range of automotive applications.New Generation ACM elastomers(described here for convenience as HT-ACM)are characterised by excellent long-term heat and fluid resistance.
