What is the ignition of PVC?
Ignition means that a substance reaches a certain temperature, it will naturally fire burning.
PVC hard plastic products is very difficult to burn, and its spontaneous combustion temperature is 256 ℃, if there is no external fire source, PVC hard products have automatic extinguishing function, it will not help combustion, and self-extinguishing, it is a flame material.
PVC characteristics and molding characteristics:
Specific gravity: 1.38 g / cm3, molding shrinkage: 0.6-1.5%, molding temperature: 160-190 ℃.
Features: 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.
Generally about 256 ℃, the special temperature of 800 ℃.
