| titleOfInvention | Process for the production of polyolefin resin foams |
| abstract | PCT No. PCT/JP98/00189 Sec. 371 Date Aug. 16, 1999 Sec. 102(e) Date Aug. 16, 1999 PCT Filed Jan. 19, 1998 PCT Pub. No. WO98/36020 PCT Pub. Date Aug. 20, 1998This invention provides a process for preparing a polyolefin resin foam, comprising the step of extruding to a low-pressure zone a melt of polyolefin resin containing a volatile blowing agent uniformly dispersed therein, the process being characterized in that the volatile blowing agent is a mixture of 5 to 95% by weight of 1,1,1,3,3-pentafluoropropane and 95 to 5% by weight of a low-boiling aliphatic hydrocarbon having a boiling point of 15 DEG C. or lower. According to the invention, there is obtainable a foam of polyolefin resin which is excellent in heat insulating property, dimensional stability and the like and which can retain them for a long term, using a blowing agent which is free of ozone-depleting risks, unlikely to adversely affect global warming, nonflammable and highly compatible with raw materials for foams. |
