High temperature resistant plastic material ( Special engineering plastics) What are the? — Mold factory need to know

High temperature resistant plastic material is often referred to as special engineering plastics, high performance engineering plastics is refers to the comprehensive performance is higher, the long-term use of temperature above 150 ℃ of engineering plastics, mainly used in high-tech, military and aerospace, aviation and other industrial fields. Called special, nature is comparatively rare and not common, many mold factory and product developers don't know about this. Special engineering plastics in Europe and the United States and Japan to develop early, and now technology is relatively mature, such as the United States dupont, Japan toray, is well-known in the field of special engineering plastics, special engineering plastics in China started relatively late, the domestic autonomous production hasn't a special engineering plastics, temporarily only Shanghai several research institute in the experiment. Special engineering plastics with its under the environment of high temperature to maintain the advantages of high performance, necessary to become a future development direction of engineering plastics, development prospect is also quite optimistic, however, due to the immature domestic technology, combined with high capital investment, as well as the reasons of slow development in China. High temperature resistant plastic materials mainly include PPS, PSF, PI, PAR, LCP, PEEK, PA46, fluoropolymer ( 聚四氟乙烯、PVDF、PCTFE PFA) Variety, etc. , high temperature resistant plastic material, the structure rigidity, corrosion resistance to high temperature is can't be matched by common plastic, is also because of its excellent performance, so expensive. Below small make up will come to you in the product development with plastic material for special needs high temperature resistant parts localization and reasonable choice. Resistance to high temperature of 250 ℃ is a lot of special engineering plastics can reach requirements, product developers in the early stage of the mold factory open mould can be further understanding of the material price and machining difficulty, material is determined to change is the trouble, because all sorts of material shrinkage, flow performance, relative mould design is certainly not the same. Can reach 250 ℃ high temperature requirements of common plastic with LCP, PPS, PA46,,,,, of the same material high temperature resistant performance according to the different type and origin is not the same. High temperature above 250 ℃, can add some fiber to improve the relative material resistant to high temperature. But with fiber a malpractice is product appearance will be a fine grain, the second with the requirements of the food-grade products add fiber is usually can't through, the somebody else say add solder is food-grade plastic that is certainly tease you play. 250 ℃ of heat-resistant plastic you have many choices, but reached 270 ℃, there are few materials can meet the requirement, then we will consider PEEK, PI, PSF,,,, resistance to high temperature of 300 ℃ is basically no problem, these materials for aerospace materials, some tall, its price is not cheap, just take a PEEK, the market price of at least 1000 per kg, also according to different models, much more expensive. A lot of the early stage of the product developers with mold factory hatred, which kind of material does this use? LCP, PEEK nearly a dozen times of price, but the LCP high temperature resistant performance is poor so little. Can choose LCP plastic products in this recommendation instant high temperature, high temperature for a long time can choose PEEK product parts, although some expensive, also just as the selling point of products. The vast net sea, I met you in da plastic products factory's website is also a kind of fate, no matter we will cooperation in the future, want to hand in your this friend, wine words life together, work together to create brilliant
