It is advisable to use a low-temperature mold of 20~40°C to tan 赜诓Agluangkong persimmon summer> 呶Lu throw Υ笥80°C. The finished product wall is thin and difficult to form or requires a mold with high crystallinity to be heated and controlled, and the embrittlement temperature is -30°C. PEI’s flame retardancy In daily life, the colored plastic products we use, such as plastic basins, plastic buckets, clothes racks and other daily necessities, sometimes fade and fade after using for a long time. What is causing this? The following is for you Analyze the reasons why the color of plastic products colored by pigments fades during use. Global warming has always been a common issue facing mankind. In most cases, this transformation can be completed within a temperature difference of two or three degrees, and it is reversible.
1. Used in the electrical industry, used in the aerospace, aviation, electronics, instrumentation, computer and other industries as the insulation layer of power and signal lines, corrosion-resistant and wear-resistant materials can be used to make films, tube sheet rods, bearings, washers, valves and Chemical pipelines, pipe fittings, equipment container linings, etc. [4]
Polytetrafluoroethylene bottle[6] 2. Used in electrical, chemical, aviation, machinery and other fields instead of quartz glassware, used in atomic energy, medicine, semiconductor and other industries for ultra-pure chemical analysis and storage of various acids, alkalis, and organic solvents. It can be made into high-insulating electrical parts, high-frequency-resistant wire and cable sheathing, corrosion-resistant chemical utensils, high-cold-resistant oil pipelines, labor, etc. It can be used as additives for plastics, rubber, coatings, inks, lubricants, greases, etc. [4]
3. This product is resistant to high temperature and corrosion, has excellent electrical insulation, aging resistance, low water absorption, and excellent self-lubricating performance. It is a general-purpose lubricating powder suitable for various media and can be quickly applied to form a dry film , To be used as a substitute for graphite, molybdenum and other inorganic lubricants. Suitable for thermoplastic and thermosetting polymer release agent, excellent load-bearing capacity. It is widely used in elastomer and rubber industry and anti-corrosion. [4]
4. Used as a filler for epoxy resin to improve the wear resistance, heat resistance and corrosion resistance of epoxy adhesives. [4]
5. Mainly used as a binder and filler for powder cakes. [4]

It is a general trend that PE pipes replace PVC pipes. The opposite is true for glass fiber that is too broken. In particular, polymer materials such as PA, PC and PET whose end groups contain groups and carboxyl groups have a more serious performance degradation during repeated recycling and processing. This has caused a great deal of simple and ordinary recycling of engineering plastics. problem. Xuzhou Tengfei Engineering Plastics Co., Ltd. is a high-tech enterprise specializing in the research and development, production and sales of various high-performance modified engineering plastics.

1. Stable under normal temperature and pressure, avoid humidity, heat and high temperature [4]
There is no real melting point, and it decomposes slowly above 450℃ and becomes a gas directly. At 327°C, the mechanical strength suddenly disappeared. Insoluble in any solvents. In addition to reacting with molten alkali metals, it is not corroded by any substance, even if it is boiled in hydrofluoric acid, aqua regia or fuming sulfuric acid, sodium hydroxide, it will not change. [4]
2. White, odorless, tasteless, powder, commonly known as “Plastic King”. It has excellent chemical stability, corrosion resistance, airtightness, high lubrication, non-stickiness, electrical insulation and good anti-aging resistance. High temperature resistance, the working temperature can reach 250℃. It is resistant to low temperatures and has good mechanical toughness at low temperatures. Even if the temperature drops to -196°C, it can maintain 5% elongation. Corrosion resistant, inert to most chemicals and solvents, resistant to strong acids and alkalis, water and various organic solvents. Good weather resistance, with aging life in plastic. High lubrication, the coefficient of friction among solid materials. Non-adhesive is the one with the smallest surface tension among solid materials and does not adhere to any substance. It is physiologically inert and has no adverse effects when implanted in the body as an artificial blood vessel and organ for a long time. [4]

However, it will cause excessive internal stress and cracking; adjust the speed and pressure of mold opening, 2. Cracks: Kewei Xing Xing Xing Xing Xing Xing Xing Xing Xing Xing Xing Xing Xun Xing Xing Xing Xing Xing Xing Xing Xing Xing Xing Xing will form a white, silver appearance on the injection molded part 3. Porosity in the finished product: molten plastic It is exposed to gas in the mold, and the temperature range is wide: -40 to 160. The following is an introduction to the performance advantages of food-grade high temperature resistant nylon PPA.
The main reason is that it achieves high performance after modification. The domestic automobile production rate is relatively fast. The problems of modified plastic products can be divided into appearance defects and unqualified performance. The appearance defects are discussed here. The tensile strength of PC/PBT alloy is about 31% lower than that without toughening agent. The molding process and mechanical processing. ABS resin is resistant to water, inorganic salts, alkalis and acids,
