PPS GF60% glass fiber filled polyphenylene sulfide 50%GF particles PPS GF 40% FR v0 PPS resin

PPS is a special engineering plastic with excellent comprehensive performance. PPS has the characteristics of excellent high temperature resistance, corrosion resistance, radiation resistance, flame retardancy, balanced physical and mechanical properties, good dimensional stability, and excellent electrical properties. It is widely used as a structural polymer material. Widely used as special engineering plastics. At the same time, it can also be made into various functional films, coatings and composite materials, which have been successfully used in electronic appliances, aerospace, automobile transportation and other fields. Domestic enterprises are active in research and development, and have initially formed a certain production capacity, which has changed the previous situation of complete dependence on imports. However, my country's PPS technology still has problems such as few product varieties, few high-function products, and urgent need for capacity expansion. This will be the focus of the next step in the development of PPS. Features Broadcast PPS features are as follows: 1. Good chemical resistance. 2. Low creep variable. 3. Low water absorption. 4. Good dimensional stability. 5. High elastic modulus. 6. Flame retardant. Polyphenylene sulfide (PPS), polyetheretherketone (PEEK), polysulfone (PSF), polyimide (PI), polyarylate (PAR), and liquid crystal polymer (LCP) are known as six major special projects plastic. Outstanding performance of PPS: good heat resistance, heat distortion temperature is generally greater than 260 ° C, can be used in the temperature range of 180 ~ 220 ° C, PPS is one of the best heat resistance varieties in engineering plastics; corrosion resistance is close to four Vinyl fluoride, second only to polytetrafluoroethylene in chemical resistance; excellent electrical properties; excellent mechanical properties; good flame retardant properties. Disadvantages of PPS: the price is too high, which belongs to the base price among high-temperature resistant materials, but it is much higher than general engineering plastics; poor toughness and high brittleness; medium viscosity is unstable. Pure PPS is rarely used because of its brittle performance, and most of the applied PPS is its modified variety. Specifically: 40% glass fiber reinforced PPS, inorganic filled PPS, carbon fiber reinforced PPS, etc.
