Classification of pvc plastic film
The pvc plastic film is made of polyvinyl chloride resin and other modifiers through the calendering process or blow molding process. The general thickness is 0.08-0.2mm, and the thickness greater than 0.25mm is called PVC sheet. Add plasticizers, stabilizers, lubricants and other functional processing additives. This film has good thermal insulation, high light transmittance, soft and easy to form, and is suitable for the outer cover material of greenhouses, greenhouses and medium-sized greenhouses. PVC film can be roughly divided into two categories, one is plasticized PVC film, also known as soft PVC film, and the other is unplasticized PVC film, also known as rigid PVC film. Among them, rigid PVC accounts for about 2/3 of the market, and soft PVC accounts for about 1/3 of the market.
The general composition of PVC film is:
PVC resin 40%~70%
Filler--1%~30%
Stabilizer 1%~10%
Colorant 1%~10%
Plasticizer--10%~50%
At present, there are two main types of commonly used plastic films in the production of raw materials: one is polyvinyl chloride film (PVC film) made of polyvinyl chloride resin, and the other is polyvinyl chloride film made of polyethylene resin. Vinyl film. (PE film) On the basis of these two raw materials, different additives are added to make the film have strong weather resistance and different special functions. These two films differ in thermal insulation, light transmittance, weight, elasticity, etc.
pe: It is flammable, and it continues to burn after leaving the open flame. The flame is yellow and blue, molten and dripping, and paraffin smell
pvc: non-flammable, extinguished immediately after leaving the fire, the flame is yellow and green with white smoke, softened but not melted, pungent and sour.
Industrial film-packed products with high tensile strength, high elongation, good self-adhesion and high transparency. It can be used for manual wrapping film, and can also be used for machine wrapping film, which can be widely used in the centralized packaging of various goods.
