CROSS-LINKABLE COMPOSITIONS FOR EXTRUSION,EXPECIALLY FOR WIRE AND CABLE COVERINGS |
摘要 |
A flame-retardant cross-linkable polymer composition for extrusion which is capable of producing non-porous products comprises: at least one flame-retardant filler of the class that evolve substantial amounts of bound water on heating at temperatures above a value Td that lies in the range 120 DEG -250 DEG C.; a compatible ethyelene copolymer base in which the filler is dispersed; a hydrolysable unsaturated silane; and a free-radical grafting initiator having a half-life of less than 10 minutes at a temperature 25 DEG C. below Td. |
