Flame retardant masterbatch

Brominated flame retardants have efficient flame retardant effect, compared to HBCD flame retardant, it can be reduced by 30% -50% of the flame retardant amount but remains unchanged effect, the decrease in the content of the flame retardant have not brings lower effect, but also more stable production can be to achieve in the state of low grade flame retardant load requirements XPS, reducing the cost of flame retardants used at the same time and also make the density of extruded board lower and the sheet surface better. Flame retardant masterbatch to promote the dissolution and dispersion of the flame retardant and PS, and has good heat resistance, the process is not easy to break down, to protect the equipment, increase production and yields. Reduces bad loss. And easy produce good flame retardant effect XPS board.
