Flame Retardant
Coated App
Product description:
Coated APP has strong moisture resistance,alkaline PH value and low water solubility after surface treatment.It can be used in expanding fireproof material,such as polyurethane,UF resin and epoxy resin,Also can be used in retardant of fiber,wood and plastic.APP is main ingredient of expanding retardant thermoplastic because of its high molecular weight and good heat stability.UL94-V0 for electronic unit made from PP shall be achieved with loading this product.
Flame retardant mechanism
The flame retardant is heated and dehydrated under high temperature conditions to generate polyphosphoric acid or metaphosphoric acid. It can be used as a strong dehydrating agent to dehydrate the carbon-forming substances in the flame retardant system to form a simple carbon layer. The non-flammable gas generated by the gas source is It forms an expanded carbon layer to isolate air and fire sources, thereby achieving efficient flame retardancy of the product.
