High Stability PVC Copolymer Resin 1-2 Um Diameter For PVC Coated Products
Description
The hard board of polyvinyl chloride is widely used in the chemical industry to make linings for various storage tanks, corrugated boards of buildings, door and window structures, wall decorations and other building materials. Due to its excellent electrical insulation properties, it can be used in the electrical and electronics industries for the manufacture of plugs, sockets, switches and cables. In daily life, PVC is used to make sandals, raincoats, toys and artificial leather!
Application
Artificial leather, wallpaper, color steel plate, foam floor, gloves, lining plastic toys or rotating casting, portrait, artificial fruit samples, plastic flowers, etc. Also applicat to compound coating, adhesive, printing ink and sealing material. PVC resin has many of simple processing equipment, cheap mold, easy foam, special shaping, processing with fewer heating, and small amount with many varieties .
