Applications

K-500 is mainly used for wire & cable PVC and soft PVC, providing equivalent effect when adding same quantity of antimony trioxide. With excellent flame retardant and smoke proof, K-500 is an excellent composite retardant with maximized flame retardant and physical properties. Multi –retarding components in K-500 cooperate well, even when added large quantity to PVC, it makes little influence to physical properties of PVC. In additional, only 3-6 shares in PVC can make perfect flame retardant effect and 5 shares in PVC can make oxygen index up to 33%. K-500 is one of the best environmental-friendly, high-effective, and safe flame retardant.
Recommended addition quantity: 3 ~ 6 PHR
