The products can be re-processed by combination, connection and cut- ting for a wide range of application such as construction, thermodynamics industry, vehicle and ship manufacture, special packaging, agriculture and fishing, recreation and sports. The article introduces technological process of the irradiation crosslinked polyethylene foam, Emphases are made mainly on characteristics of key technology including the formula, radiation crosslinking, and the foam furnace, a special manufacturing device for the foamed PE rolls. Comparisons are made between similar technologies in the field worldwide. Structure and principle of the foam furnace are given. Discussions are given on current situations and the prospect in China in research and development and applications of radiation crosslinked polyethylene foam.展开更多

As one of the fast-growing Chinese industries, the annul productions of various kinds of radiation crosslinked products totaled over 3.2 billion Yuan in 2002. Recent progresses are reviewed in radiation crosslinked cable and wires, low smock halogen-free fire-retardant heat-shrinkable materials, polymeric positive temperature coefficient materials, rubber latex vulcanization, and foamed plastics.展开更多
