| titleOfInvention | Production of expanded polyolefin resin particle |
| abstract | PURPOSE: To obtain an excellent expanded polyolefin resin particle without using any fluorocarbon blowing agent which causes an environmental pollution problem on account of its property of depleting the ozone layer, by using a mixture of two specified fluorocarbons as a blowing agent in expanding polyolefin resin particles. n CONSTITUTION: Polyolefin resin particles and a mixed blowing agent formed by mixing monochlorodifluoromethane (a) with dichlorotrifluoroethane (b) at a weight ratio of (a) to (b) of 90:10W30:70 are dispersed in a dispersing medium, and the formed dispersion is heated to a temperature higher than the softening temperature of the resin particles to impregnate the resin particles with the blowing agent. The resin particles and the dispersing medium are released into an atmosphere of a pressure lower than that in the vessel to expand the resin particles. Said mixed blowing agent is used instead of conventional trichlorofluoromethane, dichlorodifluoromethane, trichlorotrifluoroethane and dichlorotetrafluoroethane. n COPYRIGHT: (C)1989,JPO&Japio |
