New HyTemp grade for improved hose extrusion performance

Zeon Chemicals has added a new grade of HyTemp to its polyacrylate elastomer family. Intended for use in charge air cooler (CAC) hose for turbo diesel (TDi) or turbo gasoline applications and other high-performance automotive parts, HyTemp AR212XP is said to offer better polyacrylate extrusion performance, while bringing the same level of heat and fluid resistance of Zeon’s high-temperature ACM (HT-ACM) elastomers – at greater than 50 % faster extrusion rate.

According to the company, in addition to an increased rate of extrusion, HyTemp AR212XP offers benefits compared to HyTemp AR212HR, including improved extruder feeding and improved surface finish. It offers higher tear resistance, while also providing OEMs with 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.

HyTemp AR212XP was specifically designed for hose applications requiring the conveying of extremely hot air saturated with petroleum-based oils and fuels.

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. These durable elastomers can perform in a broad range of temperatures while resisting some of the most aggressive lubricants.
