HyTemp® ACM
HyTemp® polyacrylate (ACM) elastomers have excellent long-term heat resistance (up to 200°C) and compressive stress relaxation, while providing superb resistance to petroleum and synthetic-based lubricants. HyTemp is broadly used in automotive seals (engine, transmission) and turbo diesel air management hoses.
HyTemp is classified as a DF to EH polymer according to SAE J200 / ASTM D2000.

KEY ATTRIBUTES
Heat Stability
HyTemp polyacrylate (ACM) elastomers offer significant improvements in long-term high-temperature resistance compared to other elastomer families. They can be compounded to withstand an impressive temperature range from -40° to 200°C. HyTemp is broadly utilized in automotive applications including valve cover gaskets, oil pan gaskets, rocker cover gaskets, and various seals.
Petroleum and Synthetic-Based Lubricants Resistance
HyTemp ACM provides superb resistance to petroleum and synthetic-based lubricants. This resistance makes HyTemp the best choice for engine gaskets and seals.
Excellent Sealing Force Retention
Representing some of the industry’s most advanced innovations, HyTemp ACM provides outstanding long-term compressive stress relaxation (CSR) and compression-set performance at elevated temperatures.
Cost and Performance Competitive
HyTemp ACM offers a lower-cost solution versus fluorinated elastomers, including FVMQ (fluorinated silicone) and FKM (fluorinated hydrocarbon) elastomers. HyTemp enables improved oil resistance versus AEM (acrylic/ethylene) and MQ/VMQ (silicone/vinyl functional silicone) elastomers.

Automotive Engine Air Management
Air management systems for turbo-charged engines benefit from HyTemp ACM’s retention of properties at hot temperatures (175°C). HyTemp is commonly utilized for charge air cooler (CAC) hoses.
Hose manufacturers require broader processing characteristics combined with high throughput for economical production. This led to the development of the latest HyTemp ACM elastomers and specialized curative systems, which can be used for both molding and extrusion applications.
