Vinyl chloride resin-based composition and packings made therefrom |
摘要 |
An improved vinyl chloride resin-based composite material is provided by melt-mixing a vinyl chloride resin with a polymeric polyol of 300-10,000 MW and a polyisocyanate having at least three isocyanate group under shearing force while allowing said polyol and polyisocyanate to react. The composite material has a content of tetrahydrofuran-insolubles of about 5-55% by weight. The composite material exhibits chemical and physical properties suitable for use in packing and sealing applications.
