Rigid/Soft PVC Sheets / imitation marble board Extrusion Line
designed Rigid PVC sheets extrusion line adopts mixer, conical twin screw extruder, T die head, three roller calendars and downstream parts, including cooling frame and edges trimming, decoration film coating unit, corona unit as optional, haul off machine and also the transverse cutter and conveying table.
The extruded rigid PVC opaque sheets are easy to form, high tension, various colors, fireproof, high quality, low cost, applied to different kinds of fields, such as sandwich panel in construction field, furniture edge banding and skinning, high standard printing, thermoforming packing, advertising, interior decoration etc.
PVC transparent soft sheet is product instead of the traditional door curtain. It is soft, clear, insulation, safe, environmental protection, acid resistance, no peculiar smell, easy to clean, and etc, also can be used in cold and heat insulation, save energy,windproof, keep humidity, anti-corruption, fire proof, anti static. ultraviolet radiation proof, sound proof, table pad, daylighting, Industrial damping, safety warning ,protect surface, these application used in refrigeration, foodstuff, printing, weaving, electrics, instrument, medicine, storage. It has good effect on insulation for electricity, and harmful light.
The imitation marble sheets, also called “calcium powder high-filled PVC composite material”, “stone plastic material”, “high calcium material”, “imitation marble material” etc. This imitation marble sheets are featured with frienly environmentally, ultra-light and ultra-thin, super wear-resistance,high impact resistance, fire retardant, moisture and water proof, sound absorption and noise prevention, easy clean, widely used in various places, such as indoor decoration, hospitals, schools, office buildings, factories, public places, supermarkets, commerce, stadiums and other places.
