Heat-resistant plastic refers to a plastic material that can be used normally at high temperature. At present, the most common heat-resistant plastic is polypropylene. The heat-resistant temperature of polypropylene can reach 100℃, and it can be used normally in microwave ovens. The extended information of high temperature resistant plastics is as follows:

PA46

PA46 is an excellent short-term and long-term high-temperature resistant material, which can withstand temperatures as high as 200℃. According to the research, the thermal deformation temperature of unreinforced PA46 is 160℃, the short-term allowable temperature of reinforced PA46 is 230℃, and the long-term allowable temperature is 163℃. In addition, this material has high hardness, high creep resistance, high fatigue resistance and high temperature.

Postscript

PPS plastic is a special engineering plastic with strong high temperature resistance. PPS plastics can be used continuously at the maximum temperature of 400℃ after being reinforced by fiber. Ordinary PPS plastic can also be used normally at 200℃, and has the characteristics of corrosion resistance and excellent mechanical properties. At present, it is widely used in chemical industry, auto parts and household appliances industry.

Landing Craft Personnel

LCP plastics must be unfamiliar to everyone. Like everyone else, I am not familiar with LCP plastics. LCP plastics are often called liquid crystal polymers. After heating, it will form a liquid crystal form, and the continuous use temperature is 200-300℃, and the strength is 300-350℃. They have high flame retardancy and electrochemical properties. At present, they are widely used as engineering plastics in medical treatment, automobile machinery and other industrial fields.

steal a glance

PEEK is a semi-crystalline thermoplastic with excellent high stability, which can withstand the highest temperature of 260℃ for a long time and 300℃ after glass fiber reinforcement. PEEK plastic has high radiation resistance, excellent self-lubrication, mechanical properties and wear resistance, and is mainly used in heavy industries such as circuit boards, atomic engineering and electronic appliances.

High temperature resistant plastics are mostly engineering plastics and special plastics, and the temperature resistance of general plastics is mostly maintained at 70- 100 degrees Celsius. If the product has high temperature requirements, high temperature resistant materials must be selected, otherwise it will easily cause product quality problems and special accidents.
