Gasket fitted to frame and process for producing the same

摘要

There is disclosed a gasket fitted to a frame body, wherein the frame body is constituted of polypropylene produced through polymerization by using a metallocene catalyst; propylene homopolymer and/or propylene copolymer comprising propylene as a principal component each free from a lubricant; propylene homopolymer and/or propylene copolymer comprising propylene as a principal component each having been heat treated; or propylene homopolymer and/or propylene copolymer comprising propylene as a principal component each having an MFR (melt flow rate) at a temperature of 230 DEG C at a load of 2,16 kgf (21.2 N) being at most 20 g/ 10minutes as measured according to JIS K7210, and the gasket is constituted of an elastic body such as a thermoplastic elastomer, and is also disclosed a process for producing the gasket fitted to the frame body by integrating the gasket and the frame body through two-color molding method or inserting molding method. The above gasket can minimize the generation of gases which contaminate a magnetic disc and the like used in electronic equipment, and is excellent in its being lightweight and in sealability. <IMAGE>
