POSITION：HOME > PRODUCT FUNCTION > High temperature resistance Ultra high and low temperature resistant plastic There are two main ways of NFD high temperature and low temperature engineering plastics. One is to improve heat resistance by adding fibers, minerals, and high temperature additives to ordinary thermoplastic materials, and the other is to use secondary polymerization of super high temperature engineering plastics. To achieve material resistance in high and low temperature environments, the types of high and low temperature resistant modified materials currently developed by NFD include: fluoroplastics, high temperature nylon (PPA), polyethersulfone (PES), and polyetherimide (PEI) , Polyphenylene sulfone (PPSU), polyphenylene sulfide (PPS), liquid crystal polymer (LCP), polyether ether ketone (PEEK), polyarylene ether ketone (PAEK), polyamide imide (PAI), Polyimide (PI), polybenzimidazole (PBI), etc. While maintaining the high temperature resistance of plastics, NFD has improved its wear resistance, flame resistance, rigidity, toughness, corrosion resistance, chemical resistance, dimensional stability, high strength and other properties through innovative material technology. NFD high and low temperature plastics are classified as follows according to the application environment Ultra-low temperature resistant plastic refers to the long-term use temperature of -10 ℃-260 ℃, materials such as: modified fluoroplastics, UPI and so on. Ordinary high-temperature plastic refers to the long-term use temperature of less than 100 ℃, materials such as: PP, ABS, PVC, PE, PS, POM, PET and so on. Medium temperature resistant plastic refers to the long-term use temperature between 100 ° C and 160 ° C. Materials such as: PA6, PA66, PBT, PPO, PC, PTE, PA46, etc. High temperature resistant plastic refers to the long-term use temperature between 170 ℃ and 200 ℃. Materials such as: PPA, PPS, PAR, PEI, PPSU, LCP, PES, PEEK, fusible PI, amino plastic, EP, PF, F, etc. Ultra-high temperature resistant plastic refers to the long-term use temperature of more than 300 ℃, materials such as polyphenyl ester, PBI, non-melting PI, UPI and so on. 1. Use heat-resistant filler talc, calcium carbonate, wollastonite, mica, clay and other minerals to fill and modify to improve the heat resistance of plastics. The smaller the particle size of the filler, the better the modification effect. 2. The use of heat-resistant fiber glass fiber, carbon fiber, aramid fiber, whisker and other reinforced plastics to improve the heat resistance of the material. After the crystalline plastic is reinforced with glass fiber, the high temperature resistance performance is greatly improved. 3. Use high temperature resistant additives to improve the heat resistance of the material, such as phenylmaleimide, add 1% heat resistant agent to improve high temperature resistance by about 2. 4. Using the method of plastic blending modification, adding high temperature resistant materials to low temperature resistant materials, while improving the high temperature resistance of the overall material, it does not affect the performance of the material itself. 5. Use the method of cross-linking to improve the high temperature resistance of plastics. 6. Use biaxial stretching to make the crystallinity of the material finer, the arrangement more compact, increase the degree of orientation, and improve the heat resistance of the material; use the annealing heat treatment method to reduce the internal stress of the material, promote crystallization, and increase the thermal deformation temperature of the material. Regardless of the above general temperature resistance level or ultra-high temperature level, NFD can help you. From previous successful cases, NFD can provide long-term use -260 ℃ (minus 260)-high temperature 400 ℃, short-term up to 550 ℃ Plastic material. Two principles for the selection of high temperature resistant plastics: Only meet the product requirements, do not choose too high temperature resistant materials, otherwise it will waste resources and increase costs; Recommended NFD high temperature plastic models: Tepla® T8240GF (TPI) material has a long-term use temperature of 280 ° C and a thermal deformation temperature of 316 ° C.
