Crosslinkable polymer compounds for lead wire insulation, gaskets and liners in a refrigeration environment

摘要

Insulation compounds are described that have been formulated for use in a refrigeration environment. The materials consist of crosslinkable compounds made from ionomer (EAS), polyether block amide (PEBA), polybutyleneterephthalate (PBT) homo- or copolymers, and/or polyvinylidenefluoride (PVDF). The insulation compounds are intended for use as wire insulation and in the fabrication of gaskets and liners. The compounds show superior resistance to refrigerants such as HCFC-22, HCFC-123, and HFC-134a. Crosslinking provides resistance to creeping under heat and pressure.
