POLYARYLENE SULFIDE RESIN COMPOSITION AND PART FOR USE IN CONTACT WITH REFRIGERANT

摘要

A polyarylene sulfide resin composition which comprises (A) 100 parts by weight of a polyarylene sulfide resin having a melt viscosity of 50 to 1,000 Pa.sec as measured at a resin temperature of 300 DEG C and a shear rate of 200 sec<-1> and (B) 10 to 40 parts by weight of an alpha -olefin resin having a melting point of 130 DEG C or higher; and a part which is made of the composition and is for use in contact with the refrigerant of an apparatus employing a fluorocarbon refrigerant, such as a refrigerator or air-conditioner. Examples of the part include compressor parts which come into direct contact with a refrigerant. The polyarylene sulfide resin composition is lightweight, is excellent in heat resistance and sliding properties, and has a satisfactory balance between these properties and resistance to fluorocarbon refrigerants.
