Superiority:

This product is an environmentally friendly flame retardant. It is a new generation of permanent flame retardant modified based on the structural characteristics of polyester. Compared with CEPPA, it has the characteristics of high phosphorus content, low relative addition, and good thermal stability. The flame-retardant chips have a higher melting point than the flame-retardant chips produced by CEPPA, which can reach 256°C. It is not easy to produce floating yarn breakage during spinning, and can spin finer polyester products.

Uses: As one kind of environment-friendly fire retardant, it is a new kind of permanent flame retarding modifier. Compared with CEPPA, it contains less phosphorus, has lower dosage and better thermal stability. The Melting point of its products is higher than that of CEPPA's products, or even reach to 256oC. It can be used to produce thinner polyester products for it is hard to breakage.
