EPS/XPS flame retardant(FR-972)

Product description： This is a new additive flame retardant, which is mainly used for EPS, XPS. It has the advantage of low dosage, good flame retardant effect, less influence on the physical properties of materials, good thermo-stability and UV stability. It has better flame retardant efficiency than brominated aromatic flame retardants. It is an excellent alternative of HBCD. Benefits： 1. Better flame retardant effect than HBCD. 2. More excellent heat-resistance. 3. Better comprehensive performance in the EPS/XPS sheets. 4. Lower smoke density. Specification： Items Units FR972 Appearance --- White powder Bromine content % 65 min Moisture % 0.3 max Melting point ℃ 110 min Decomposition temperature 5%,℃ 280 min Flammability % B1：5-6 B2：3-4 Application： 1. As the main flame retardant has a low melting point, it is recommended that the product is used on double-screw XPS production equipment, and lower the temperature of feeding stage. It also application to the single-screw production line, but should use reasonable processing technology. 2. All the dosage above is a suggestion, the exact loads depend on the viscosities of the polystyrene resins, process conditions and the final application. 3. When stopping the production process and at the end of each run, immediately purging is necessary. Packaging and Handling: 25kgs/bags with PE inner，handle with care, cold storage. In ventilated and dry condition.
