Extruded product of foamed rubber

摘要

The invention is to provide an extruded product of a foamed rubber satisfying requisite features as to the abrasion resistance or the surface skin in the glass run, while maintaining the foaming magnification enabling to reply the demands of the weight lightening. An ethylene-alpha-olefin based rubber is substantially a raw rubber, and is extruded from a compounded material of the foamed rubber prepared (vulcanized material) with a thermal decomposition typed foaming agent. This extruded product of the foamed rubber has physical properties of foaming magnification: 1.05 to 1.55, bubble diameter: 110 mum or less, and thickness of skin layer: 130 mum or more.
