How to correctly distinguish between pp and pvc soft board
Aug 18, 2017

A lot of people have the PP board and PVC soft board to distinguish the wrong situation. The two plates are made with different materials, effect nature is also different, but in the plastic industry is now in the PP board and the PVC soft plate has been the development of two kinds of plank best, because many customers do not understand the difference between these two plates, so the purchase when encountered the difficulties.

Thermal stability of PVC soft board is very bad, at 80 degrees 130 degrees began to soften, begins to break down, and the release of HCL gas, PVC electrical insulation than PP plate, usually for low voltage and low frequency of insulating material. PVC soft board can resist most inorganic acids, alkalis, salts and most organic solvents.

And PP board is tasteless, odorless, non-toxic, completely in line with national health standards, small density, is the most common plastic one of the lightest. It can be boiled in water, sterilized with 120 degrees steam, and can be used for 100 years at a temperature without deformation. It also has excellent electrical insulation and chemical stability, almost no water absorption, and the vast majority of chemicals in contact, will not work. PP corrosion resistance, acid, alkali and so on. However, the PP board has its disadvantages, such as low temperature resistance, poor impact and relatively easy aging, but can be overcome by modifying and adding antioxidants respectively.
