2. Yarong Bio-TCPPFlame Retardant

1) General description and application

•TCPP is a chlorinated phosphate Flame Retardant, usually used for rigid polyurethane foam (PUR and PIR) and flexible polyurethane foam.

•TCPP, sometimes called TMCP, is an additive Flame Retardant that can be added to either of the two sides to achieve long-term stability by a combination of urethane or isocyanurate.

• In the application of rigid foam, TCPP is widely used as part of the flame retardant to make the formulation meet the most basic fire standards such as DIN 4102 (B1/B2), EN 13823 (SBI, B), GB/T 8626- 88 (B1/B2), ASTM E84-00.

• In the application of soft foam, the combination of TCPP and melamine can reach BS 5852 crib 5 standard.

3. Yarong Bio-BDPFlame Retardant

1) General description and application

•BDP Flame Retardant is a halogen-free Flame Retardant belonging to the oligomeric phosphate class. It is based on bisphenol A and bisphosphate as monomers. BDP Flame Retardant is especially suitable for engineering resin alloys, including those used in electrical and electronic accessories PC/ABS and PPO-PPE/HIPS. According to fire safety standards, the amount of BDP is usually about 8 to 18 phr. Compared with other brominated Flame Retardant, BDP does not require any synergist (usually antimony oxide), Therefore, it has a good circulation ability.

• In addition, it also has good low volatility and thermal stability during the production process of most engineering thermoplastic resins. Due to the obvious fluidity of BDP, thin-walled molds can be produced. Finally, compared to other Flame Retardant, its water resistance The solution is more superior.
