Application:
Environmentally friendly flame retardant, suitable for the production of permanent flame retardant polyurethane products such as polyester chips, filaments, staple fibers, fabrics, and films. The obtained polyurethane chips have good hue and good spinnability. Compared with conventional PET, the spinnability of flame-retardant polyester products after adding this product has the same spinning and tensile properties as conventional polyester chips. Flame-retardant polyester products 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 has good spinnability. The fiber has good weaving properties and can be passed through any spinning. The silk system performs spinning processing, and the fabric can obtain permanent flame-retardant properties. 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 flame retardant oxygen index after spinning fabric is 30~36%. It is widely used in flame retardant fields such as textile flame retardant, spinning flame retardant, chemical fiber flame retardant, various clothing materials, decorative fabrics, etc.
Storage:
Being kept in dry, clean warehouse with well ventilation.
Avoid exposing to light and heating.
Protecting the product from leakage, rain and insolation during transportation.
