PP flame retardant sheet is a kind of plastic sheet made of polypropylene (PP) as the main raw material, adding flame retardant and other additives, with good flame retardant properties and chemical stability.
It has good flame retardant property and chemical stability.
– Flame Retardant Properties
– PP flame retardant material can absorb the heat generated during combustion, play a role in cooling and slowing down the combustion rate. And can provide a layer of isolation layer isolated from oxygen, due to the isolation of oxygen and self-extinguishing, such as some flame retardant combustion generated by the phosphide that is isolated from the oxygen of the isolation layer; but also generate a plastic can be reacted with free radicals, and their reaction products with the plastic can play a role in flame retardant. Containing PP flame-retardant articles in the combustion can produce a kind of gas that can extinguish the flame.
– Physical Properties
– Small density, strength stiffness, hardness heat resistance are better than low-pressure polyethylene, can be used at about 100 degrees, has good electrical properties and high-frequency insulation is not affected by humidity, low-temperature brittle, not resistant to mold easy aging.
– It is semi-crystalline material, harder than PE material and has a higher melting point.PP extrusion sheet is light, uniform thickness, smooth and flat surface, good heat resistance, high mechanical strength.
– Chemical Properties
– It has excellent chemical stability, can resist acid and alkali corrosion, anti-oxidation, UV resistance, non-toxic, tasteless, colorless and harmless, and low expansion rate, superior welding performance, reliable insulation, easy to process, etc. It is an excellent thermoforming material and corrosion-resistant material.
