Non Adhesive PVC Film
PVC film (polyvinyl chloride film), which is made of polyvinyl chloride resin and other modifiers through calendering process or blow molding process. The general thickness is 0.08~0.2 mm, larger than 0.25 mm is called PVC sheet.
Detailed introduction
Functional processing aids such as plasticizers, stabilizers, and lubricants are added to the PVC resin, and the film is formed by calendering. This shed film is thermally insulating, transparent
Good light, soft and easy to shape, suitable for the outer covering of greenhouses, greenhouses and small and medium-sized sheds. The disadvantages are: the specific gravity of the film is low, the cost is high; the weather resistance is poor, and it becomes hard at low temperature
Embrittlement, easy to soften and relax at high temperature; after the additives are precipitated, the film surface is vacuumed, which affects the light transmission; the residual film cannot be degraded and burned.
Main features:
Polyvinyl chloride film is insoluble in water, alcohol, gasoline, and can swell or dissolve in ether, ketone, chlorinated aliphatic hydrocarbon and aromatic hydrocarbon. At room temperature, it is resistant to concentrated hydrochloric acid, 90%
of sulfuric acid, 50%-60% nitric acid and 20% or less caustic soda solution.
Application:
Generally, it is used the largest amount in electrical aspects, namely electrical adhesive tape. According to its characteristics, it can also be used for protective adhesive tape, luggage adhesive tape, marking adhesive tape, advertising sticker, pipeline adhesive.
Adhesive tape, etc. It is also widely used in daily life, such as shoes, toys, raincoats, tablecloths, umbrellas, agricultural films, etc.
