Specification:

Application:

CEPPA can be used for PET polyester fiber, nylon, FRP, etc,widely used in flame retardant fields such as textile, spinning, synthetic fiber, clothing materials, decorative fabrics, etc.

CEPPA is environmentally friendly flame retardant, suitable for the production of polyester chips, filaments, staple fibers, fabrics, films and other permanent flame retardant PET products. The obtained polyurethane chips have good hue and good spinnability.The spinnability of CEPPA added PET chips has the same spinning and tensile properties as conventional polyester chips.It has excellent thermal stability, does not decompose during the spinning process, and has no peculiar smell at the spinning site. It can improve the antistatic performance of polyester products and make the fabric permanently flame retardant.The modified PET chips have good spinnability. The fiber has good weaving properties and can be processed through any spinning system.

CEPPA and PTA, EG produce flame-retardant polyester chips through copolycondensation reaction. Before polycondensation, CEPPA can be pre-esterified with ethylene glycol under appropriate conditions until the esterification rate reaches about 80%. The polycondensation conditions of flame-retardant polyester chips are similar to those of conventional chips. The flame-retardant groups are embedded or connected to the polyester molecular chain to form a permanent flame-retardant polyester. When copolymerized with PTA and EG, the additive amount is 2.5~4.5%, the phosphorus content of flame-retardant polyester chips is 0.35-0.60%, and the LOI is 30~36%.
