LIMAX CHEMICAL engages in developing and producing cost-efficient flame retardants for use in polycarbonate (PC) and its alloys.
PC and PC alloy are both versatile engineering plastics. Normally, in order to achieve UL94 V-0, flame retardants need to be added directly or through a master-batch into the resin before compounding or processing into a final product.
As a player in PC and/or PC alloys processing or compounding, are YOU currently facing any challenge when using flame retardants for PC and PC alloys? We, LIMAX CHEMICAL, have developed a novel flame retardant, LC-160, for PC and PC alloys.
- LC-160 is a halogen-free flame retardant. It conforms to RoHS and REACH – SVHC.
- Generally, the FR efficiency of LC-160 can match and even exceed that of a sulfonate-type flame-retardant such as KSS, HES and KPFBS at a similar dosage in pure PC, but for a much lower price.
- LC-160 shows strong synergy with siloxanes, PTFE, phosphate ester FR and sulfonate FR in formulation of pure PC.
- LC-160 is widely used in a unique combination with a phosphate ester flame retardant like RDP or BDP in transparent PC, PC thin film or PC alloys such as PC/ABS , PC/PBT , PC/PET and PC/PS to reduce the amount of the original phosphate ester FR, thus boosting cost-efficiency and raising heat deflection temperatures (HDT).
- Use of LC-160 contributes to high transparency of PC & PC alloy.
- LC-160 disperses well in PC melt during processing. Its very low level of moisture-absorption further facilitates its use and storage.
LC-160 is normally used at a dosage of 0.1% – 0.2%. A further increase is likely to depend on trial outcome. However, just like KSS, HES and KPFBS, too high a dosage of LC-160 might cause some degree of degradation.
