for Glass-fiber Reinforced PBT
 (HT-202C)
Product Description
1. Description
HT-202C is a kind of halogen-free and intumescent flame retardant with the major flame retardant elements N and P, compliance with RoHS and REACH regulations, no migration, no precipitation. HT-202C has many properties such as halogen-free, environment-friendly, excellent flame retardancy and water resistance, the flame retardant PBT with HT-202C does not release phosphine (phosphine test report No. is SCL01G019381C,certificated by CTI). HT-202C is an ideal substitute of bromine-antimony in glass-fiber reinforced PBT.

3. Conclusion
(1) The flame retardancy of the glass-fiber reinforced PBT can reach UL 94 (1.6mm) V-0 when adding 20% of HT-202C. 
(2) The comprehensive properties of the glass-fiber reinforced PBT with HT-202C are excellent, some properties are superior to that of PBT with bromine-antimony.
(3) HT-202C could completely substitute DBDPE/ATO in glass-fiber reinforced PBT. 
4. Attention Concerned
(1) Control the processing temperature below 260℃ in vacuum condition and use weaker shear screw combination.
(2) Never contact with any strong oxidizing substances (such as antimony trioxide), otherwise causing the product discoloration.
