HyTemp ® Polyacrylate Applications
GASKETS & SEALS
Automotive-related demands on elastomers continue to become more severe. This is a trend that appears to be continuing unabated. Not only are the temperature demands becoming greater, but the specification-related constraints both in time and newer test techniques, such as compressive stress relaxation (CSR), are more demanding as well. This combination is requiring suppliers to turn to ever more exotic, yet cost-effective, polymers and cure chemistry in order to fulfill modern automobile specifications.
HyTemp polyacrylate (ACM) elastomers offer significant improvements in long-term high-temperature resistance, and their use and superiority in a number of demanding automotive applications including valve cover gaskets, oil pan gaskets, rocker cover gaskets, and various seals have already been successfully demonstrated. These applications, where sealing force retention for >160,000 kilometers is a typical expectation, require the excellent long-term high-temperature performance, excellent compression set, compressive stress relaxation (CSR) resistance, and stable modulus that these elastomers provide. |

HyTemp® ACM elastomers perform extremely well in the hot and oil-laden environments anticipated in such applications as TDi/CAC hose, TOC hose, power steering hose, and many others.
|
|
ACM elastomers provide enhanced, long-term performance for the most demanding heat- and oil-resistant gasket and seal applications.
|
|
HyTemp® ACM elastomers are ideal binders for flexible magnets used in close proximity to electric motors where heat and ozone buildup will attack unsaturated binders.

The tackiness of polyacrylates, coupled with good heat and oil resistance, makes HyTemp® ACM ideally suited for adhesive, caulk, and sealant applications.
