Comparison of PP hollow board and other plastic sheets
The chemical name of PP hollow board is polypropylene hollow board. Its density is only 0.91 grams per cubic centimeter, which is less than the density of water. Among the common plastic plates, PP hollow board has the best heat resistance and its resistance The heating temperature is 80~100 degrees Celsius, and it can be boiled in boiling water again. It has good stress resistance and high fatigue life.
PP hollow board has excellent electrical insulation, its water absorption is extremely low, and the electrical insulation will not be affected by humidity. The dielectric constant and dielectric loss factor of pp hollow board are very small and are not affected by frequency and temperature. Its dielectric strength is very high and increases with temperature. These attributes are all The insulating material is strong, so PP hollow board is very popular in some occasions requiring insulation function.
