PP and PVC sheet, which performance is good?

PP and PVC sheet, which performance is good? What is the lower price Engineering design is the PP board, if it is in the acidic environment, PVC board can replace the PP board?


Mainly to see you use the direction of the. PVC mechanical properties, excellent electrical properties, strong acid and alkali resistance, chemical stability, but low softening point. Suitable for the production of thin, wire and cable insulation, seals and so on. PP its excellent electrical properties, can be used as high-temperature insulation materials, high hardness, high hardness. It can be said that the market is usually two mixed applications. The price is high PP board. PP can replace the PVC board, but in general or PVC board acid good
Yes. PVC board is inherently resistant to corrosion!
PP: odorless, non-toxic, tasteless in line with national health standards, density, is the most common kind of plastic in a plastic. Can be boiled in the water, 120 degrees steam disinfection, can be used at 100 degrees temperature long-term deformation. At the same time with excellent electrical insulation properties and chemical stability, almost no water, and most of the chemical contact does not occur. PP corrosion resistance, acid and so on. The disadvantage is poor resistance to low temperature impact, easier to aging, but can be modified and added antioxidants were overcome. PVC: PVC heat stability is very poor, 80 degrees began to soften, 130 degrees that began to break down, and the release of HCL gas, PVC electrical insulation as PP, generally suitable for low pressure and low frequency insulation materials. PVC can withstand most of the inorganic acid, alkali, salt, most organic solvents. PP plate prices generally 20-35 yuan per kilogram, PVC sheet prices per kilogram ranging from 5-20 yuan, different grades of plate prices are different, the same 1CM thick PP sheet of a square meter about 9.5 kg, while the PVC sheet of a Square meters about 18 kg.
