Aluminum hypophosphite(FR-ALP)

Product description：

This is a new type of flame retardant, slightly soluble in water, non-volatile. As the high phosphorus content and good thermal stability, it has better flame retardant efficiency and does not cause the decomposition of polymer when processing. Also, it can make the product has excellent mechanical and comprehensive properties. Widely used in ABS, PA, PET, PBT, PO, TPU etc.

Benefits：

1. High phosphorus content, good FR efficiency.

2. Excellent thermal stability.

3. Halogen-free system.
