Product Usage:
RK-370 is an additive flame retardant, used in PP and HIPS, the flame retardant grade reaches V-2 (UL94 standard), and has significant UV resistance and light stability. Originally designed to find a newer and better flame retardant in the rapidly growing polypropylene field. The combination of high bromine content (70%) and high phosphorus content (3%) enables it to achieve a better flame retardant effect with a very low addition amount. The brominated part in the product structure endows it with excellent UV and light stability, ensuring the excellent appearance of the finished product.
The high melting point (181°C) of RK-370 allows it to be processed into high-purity filler masterbatches. In addition, since RK-370 can be melted and mixed, it melts at the processing temperature of PP, which is easy to process and improves product flow. It solves the problem of surface blooming on flame retardant PP that could not be solved before.
