Elastomer extrudes faster, offers heat, fluid resistance in fuel systems

A new grade of polyacrylate elastomer extrudes at a 50% faster rate while bringing the same level of heat and fluid resistance in charge air cooler (CAC) hoses for turbo diesel (TDi) or turbo gasoline applications and other high-performance automotive parts. Zeon Chemicals HyTemp AR212XP also reportedly offers improved extruder feeding and surface finish compared to the prior grade, HyTemp AR212HR.

Zeon says the material provides high tear resistance, while also offering OEMs improved dynamic performance in the end-use application. Additionally, AR212XP offers manufacturers the ability to use an increased level of filler loading to attain equivalent hardness but achieve an increase in ultimate elongation.

Zeon Chemicals' family of HyTemp polyacrylate elastomers have traditionally been used for the sealing or conveying of fluids used in engines, automatic transmissions, or power steering systems, while HyTemp AR212XP was specifically designed for hose applications requiring the conveying of extremely hot air saturated with petroleum-based oils and fuels.
