ZJYC New Material Technology Co., Ltd. was established in 2007 and is a wholly-owned subsidiary invested by the listed company ZJXH Group.
The company's main focus is on PPS fiber and nylon PA6, PA66 & HTN fiber, combined with other special materials business, to develop and sell a series of special fibers. PPS fiber is made by the company with independent intellectual property rights technology, based on high-quality PPS raw materials, and through a special process of independent design and development. The product has the advantages of high temperature resistance, radiation resistance, low viscosity, high dimensional stability, good flux resistance and chemical resistance, excellent dielectric properties and wear resistance, and is widely used in the automotive industry, machinery manufacturing, electronic appliances, environmental protection , Military, aerospace, textile and other industries.
In the future, the company will extend the new material industry chain on the basis of existing technologies and markets, with PPS fiber and nylon fiber as the main support, continue to develop and improve other series of special fiber varieties, expand the fiber business scope, and strive to become a Competitive and influential industry leader in specialty fiber products. The company will continue to enrich the product line, provide downstream customers with a full range of products, better provide customers with quality services, and promote the vigorous development of the specialty fiber industry.
The PPS molecular chain is composed of benzene rings alternately connected by para-sulfur atoms. The molecular structure contains rigid, heat-resistant phenylene and flexible heat-resistant sulfide bonds, and the rigid structure of the benzene ring is composed of flexible sulfides The keys are connected, so the fibers have better heat resistance and thermal stability than conventional fibers. It has excellent strength, rigidity and fatigue resistance at high temperature. It can be used continuously at 200 ~ 240 ° C. It is stable in air or nitrogen below 400 ° C and has almost no weight loss. Its chemical resistance is similar to that of polytetrafluoroethylene (PTFE), known as the "King of Plastics". It can resist the erosion of acids, alkalis, chlorohydrocarbons, hydrocarbons, ketones, alcohols, vinegar and other chemicals, and is insoluble at 200 ℃ In any chemical solvent. At the same time, it has excellent flame retardant properties, with a limited oxygen index (LOI) of 34%. It can burn on the flame, but it will not drip, and it will extinguish itself from the fire. The smoke rate is lower than the halogenated polymer.
The PPS fiber is made of polyphenylene sulfide by melt spinning and has a melting point of 285 ° C. Amber color, strength 0.18 ～ 0.26N / tex, elongation 25% ～ 35%, initial modulus 2.65 ～ 3.53N / tex. With good heat resistance, it is mainly used as high-temperature filter fabric, withstand temperature up to 190 ℃. The fiber also has excellent chemical resistance and hydrolysis resistance, as well as flame retardant properties. It can be used as flame retardant fabric, home decoration fabric, flue gas filter material, etc.
Excellent physical and chemical properties of PPS fiber products
① Excellent heat resistance: It has excellent strength, rigidity and fatigue resistance at high temperature. After 2000 hours of high temperature air at 204 ℃, 90% of the strength is retained, and after 1000 hours at 260 ℃, 60% Intensity, it can be used continuously for 30,000 hours under the condition of 170 ℃ coal-fired power plant.
② Superior corrosion resistance: The chemical resistance of PPS fiber is similar to that of polytetrafluoroethylene, which is known as the "King of Plastics". It is insoluble in any chemical solvent at 200 ℃.
③ Excellent flame retardant performance: The limiting oxygen index is 34 ～ 36, without adding any flame retardant, it can reach the UL-94V-0 standard, and the flame retardancy detection and analysis of the materials in the aircraft cabin is carried out by the test center of CAAC , Meet the requirements of CCAR 25.853 (d) and ABD0031 (7-4).
④ Excellent electrical properties: the dielectric constant is 3.9 to 5.1, the dielectric strength (breakdown voltage strength) is 13 to 17 kV / mm, and the volume resistivity is 4 × 1016Ω · cm. The surface resistivity is 8 × 1015Ω, the electrical strength is> 18kv / mm, and it can maintain good insulation under high temperature, high humidity, frequency conversion and other conditions.
⑤ Good physical properties: PPS is equivalent to polyester in strength, elongation and elasticity, and it has better insulation against gamma rays and neutron radiation than polyamide and polyester.
