Do PP Flame Retardant Sheet, Is It Better to Choose Copolymer Flame Retardant or Homopolymer Flame Retardant?

Do PP Flame Retardant Sheet, Is It Better to Choose Copolymer Flame Retardant or Homopolymer Flame Retardant?

The production of PP sheet usually uses homopolymer PP raw materials, copolymer PP raw materials, etc., and according to the needs of users use different materials. PP sheet made of homopolymer PP flame retardant has good transparency, low price, strong rigidity, but poor toughness; PP sheet made of copolymer PP has the characteristics of flexibility, impact resistance, anti-aging and expensive.

Because the brittleness of homopolymer PP flame retardant is greater than 0°C, many more are made of copolymer PP. PP at the Vicat softening temperature of 150°C. The material has good surface stiffness and scratch resistance due to its high crystallinity. pp does not suffer from environmental stress cracking. In general, PP is modified by adding glass fibers, metal additives or thermoplastic rubber.

Therefore, when users choose flame retardants, they should combine their own conditions can choose Yinsu company, using homopolymer PP material + homopolymer flame retardant, copolymer PP material + copolymer flame retardant. Such as for the addition of glass fiber PP material recommended copolymer flame retardant.

The above is the interpretation of all the content, to learn more about wire and cable flame retardants, fabric flame retardants, rubber flame retardants, plastic flame retardants, please continue to pay attention to our website.
