PURPOSE: To improve tensile strength, tensile elongation, low temperature brittleness and anti-abrasion properties by compounding PE carbon black, antioxidant agent, processing aid and organic peroxide curing agent to an ethylene- vinylacetate copolymer. n CONSTITUTION: To 100 pts. of an ethylene-vinylacetate copolymer (A) with a content of vinylacetate of 8-14 pts.wt. (29-36 pts.wt. of PE (B) with a density of 0.90-0.95, 19-25 pts.wt. of carbon black (C) with a surface area of 650-1200 m 2 /g, 0.1-5 pts.wt. of an antioxidant (D) (e.g. etrakis (methylene (3,5-di-tert- butyl-4-hydroxyhydrocinnamate))), 0.1-3 pts.wt. of processing aid (E) (e.g. zinc stearate), and organic peroxide curing agent (F) (e.g. dicumylperoxide) are compounded. n COPYRIGHT: (C)1989,JPO |
