What are the characteristics and uses of polyvinyl chloride (PVC) calendered film?1

PVC calendered film is based on polyvinyl chloride resin. A closed-cell foam plastic is made by adding auxiliary materials such as foaming agent and stabilizer, and kneading, ball milling, molding and foaming. In addition to the soft and hard performance of technical products, there are three types of soft, broken and calibrated. The characteristics of PVC calendered film are light weight, thermal insulation, sound absorption, good shockproof performance, low water absorption, acid and alkali resistance, good oil resistance, and no burning. Because its high-temperature plant decomposes the gas produced by cattle, it does not burn and extinguishes itself, so it is a self-extinguishing material, suitable for occasions with high fire protection requirements. The products of polyvinyl chloride foam are generally boards, which are often used as insulation materials for roofs, floors, traps and walls, as well as core materials for sandwich panels. PVC calendered film is made of polyvinyl chloride resin——Quantitative anti-aging agent, gender-changing and other auxiliary agents are sweat-shaped decorative materials made of B by mixing, calendering, vacuum forming, etc. It has the advantages of light weight, moisture-proof, cloudy and hot, non-flammable, wood vacuuming, non-breaking, paintable, easy to install, and low price. It is used for indoor ceiling or moisture surface decoration of theaters, conference barriers, shops, public facilities and residential buildings. Polyvinyl chloride plastic floor is made up of polyvinyl chloride resin, mineral filler, plasticizer and pigment. It has the advantages of light cloth, oil resistance, wear resistance, corrosion resistance, fire resistance, sound insulation, heat insulation, dimensional stability, durability, comfortable foot feeling, convenient application and good decorative effect. It is suitable for the decoration of residential, public buildings, industrial plants and other floors, and can also be used for acid and alkali resistant floors.
