High speed method of making microporous film products |
摘要 |
Microporous film products permeable to moisture vapor and which act as barriers to liquid are made by a high speed method. Such microporous products are made at speeds in the order of above 500 fpm to about 1200 fpm. Thermoplastic polymers are melt blended to contain about 35% to about 45% by weight of a linear low density polyethylene, about 3% to about 10% by weight of a low density polyethylene; about 40% to about 55% by weight calcium carbonate filler particles, and about 2% to about 6% by weight of a triblock polymer of styrene. <IMAGE> |
