The flame retardant of polyester (PET) fiber is currently mainly used to add flame retardants or react flame retardants into the molecular structure to play a flame retardant effect. Additive halogen-free flame retardants cannot effectively adhere to polyester poly The flame retardant effect is generally poor on the ester fiber thread, or the flame retardant effect cannot be sustained, and it does not have permanent flame retardant function; and the 3-HPP/CEPPA phosphorous flame retardant is a reactive halogen-free flame retardant, its principle It is a permanent flame-retardant polyester polyester chip synthesized by copolymerization with terephthalic acid (PTA) and ethylene glycol (EG). Because 3-HPP/CEPPA participates in the polymerization reaction, a macromolecular structure is formed, so this product is obtained Flame retardant polyester chips have good spinnability and permanent flame retardancy; this product has high flame retardant element phosphorus content (14.5%) and good flame retardant effect. When synthesizing flame retardant polyester, add 4-5% ( (Weight percentage) polyester fiber chips made of 3-HPP/CEPPA flame retardant, the oxygen index can reach 32-33%; the reactivity is good, and high-molecular-weight polyester chips can be obtained; non-toxic and tasteless, with high heat Stability, oxidation stability and water resistance. This product is especially suitable for polyester chip manufacturers to produce high-quality flame-retardant polyester chips.

Packing:25kg /bag /carton or 500kgs/bag.


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.

Can a shift in consumption structure lead to a shift in chemicals demand structure?   For the chemical market, in the current global market consumer market downturn under the general trend, the emergence of 618, whether to boost China's consumer market, so as to reverse drive the chemical consumer market "warming", is currently the chemical industry is very concerned about things.   For large home appliances and small home appliances used in the chemical materials, due to its application environment, body type and function of the different chemical materials used in the product there are differences.   First, the shell of the chemical materials used in the differences. The shell of large home appliances are mostly ABS, HIPS, etc., a small number of applications of PP, PC, ASA and other new materials, of which the application of ABS accounted for the largest proportion of air conditioners, washing machines and other shells are mostly ABS, the shell of the refrigerator is generally two kinds of materials, one is a steel plate, the other is a BS material. Steel plate is a common metal material, it has high strength, high hardness, not easy to deformation, etc., and the appearance of beautiful, durable.BS material is a polymer material, it has a lightweight, good toughness, impact resistance, etc., and a variety of colours.   Small appliances shell is mostly PC and ABS-based, but also choose steel, PP and so on. Such as air fryer shell is mostly ABS material, air deflector groove more PPS material. Sweeping robot shell is mostly ABS material, internal seals, tyres and other material applications there is also diversity.   Second, there are differences in the materials used for special internal parts. Different large home appliances, their internal functions are different, the material used also has a big difference. Air conditioner internal filter using mostly fibre materials, such as polypropylene fibre and polyester fibre and other materials, air outlet materials using flame retardant PP and flame retardant ABS materials, all modified plastics, the need to have a high degree of flame retardancy and so on. Refrigerator internal panels mostly use PMMA acrylic materials, freezer extraction mostly use antibacterial modified HDPE and transparent modified PP materials, there are a few ABS modified materials. Washing machine internal mostly use PP, HIPS, ABS materials, etc., there are flame retardant modified materials, enhanced toughened modified materials, etc..   For small home appliances, air fryers use PPS materials for their air guide grooves, which require high temperature resistance, dimensional stability and machinability. Rice cookers use steel inner liner, and the bottom wire connection materials use flame-retardant PP, flame-retardant ABS and other flame-retardant materials. The dust box inside the sweeping robot mostly uses HDPE injection material, and the tyres are mainly natural rubber and styrene-butadiene rubber tyres, which are resistant and easy to be processed.   Third, with the emergence of new electrical appliances, the application of electronic materials in home appliances is rapidly increasing. Such as "five constant" air conditioning, sterilization and deodorization of the fresh air system, can be connected to the washing machine and refrigerator, etc., these "smart" home appliances, a large number of the use of electronic materials, such as large-area touch panels and screens, and the Internet system requires new material products. In my opinion, these new appliances have a lot of potential.   In my opinion, these new home appliances are likely to be the main trend of upgrading China's home appliances, and will also drive the development trend of home appliance design and production. Under such a trend, a large number of electronic material products are expected to be used on home appliances, such as LCP, wet electronic chemicals, carbon fibres and composites, network hardware materials, PVA, PI, PET, PTFE, PVDF and so on.
