Introduction of hollow corrugated sheet flame retardant materials
The hollow board is a new type of material that is light in weight, non-toxic, non-polluting, waterproof, shockproof, anti-aging, flame retardant, corrosion resistant and rich in color. Compared with injection molding products, hollow plates can be flexibly designed and directly extruded, without the need to open injection molds. Do you know the flame retardant material of the hollow board?
The hollow board is mainly made of two materials, one is made of environmentally friendly and pollution-free recyclable thermoplastic polypropylene (PP) and various excipients, and the other is made of a polycarbonate (PC) hollow board, which is high performance. Engineering plastic PC resin processing, which is mostly PP hollow board, however PP is a very flammable material, the limiting oxygen index is only 17.5, the char forming rate is almost 0, easy to melt and drip, due to electronic appliances, In the construction industry and other industries, the requirements for flame retardant are getting higher and higher, so the flame retardant of PP hollow board is very necessary.
The flame retardant of PP hollow board can be classified into halogen-free flame retardant, halogen-free flame retardant and low halogen flame retardant according to the content of halogen (halogen including fluorine, chlorine, bromine, iodine, antimony).
