Detailed
PVC is polyvinyl chloride, which is a polymer polymerized by vinyl chloride monomer (VCM) in peroxides, azo compounds and other initiators or under the action of light and heat according to the mechanism of free radical polymerization. It is a white powder with an amorphous structure, with a small degree of branching, a glass transition temperature of 77~90 °C, and a decomposition of about 170 °C, poor stability to light and heat.
Purpose
1. Polyvinyl chloride pipe
PVC can be made of polyvinyl chloride pipes, made into drainage pipes, water supply pipes, electrical line pipes, etc., with good pressure resistance, corrosion resistance, acid and alkali resistance, very small friction on the pipe wall, and fast fluid speed. PVC pipe is a good plastic pipe, excellent performance, can be used in a wide range.
2. polyvinyl chloride film
PVC film is a film made by mixing PVC with other additives, which can be cut to process packaging bags, raincoats, tablecloths, toys, etc. In addition to daily life, PVC film is used in electrical aspects is very large, according to the characteristics of PVC film can be used in protective adhesive tape, advertising stickers, luggage adhesive tape and so on.
3. PVC packaging materials
PVC can be combined with other polymers to make laminates and transparent products. For example, mineral water bottles, beverage bottles, cosmetic bottles, etc., have good barriers.
4. PVC hard materials and plates
PVC is then added with stabilizers and other fillers, and can extrude various hard pipes, corrugated pipes and so on after mixing. It can also be pressed into thin sheets to make rigid sheets and cut into the desired shape. It can also be welded into various storage tanks and containers with PVC electrodes, and the corrosion resistance is very good.
5. Foam products
When PVC is mixed, foaming agents can be added to make foam plastic, which can be used to make foam slippers, foam insoles, and shockproof packaging materials.
