High temperature resistant nylon (PPA) is a kind of heat-resistant polyamide that can be used in 150 ℃ environment for a long time. At present, the high temperature resistant nylon that has been industrialized is mainly pa4t, PA6T, PA9T, pa10t, etc.

Because the performance of traditional engineering materials can not meet the requirements of high temperature resistance of some products, the use of special engineering plastics will lead to high production costs. After balanced consideration, high temperature resistant nylon has become a cost-effective solution, which is highly competitive in the market.

Compared with ordinary nylon materials, high temperature resistant nylon has higher melting point and better mechanical properties. The main reason is that aromatic rings are added to the polyamide molecular chain of high temperature resistant nylon, which reduces the activity of the whole molecular chain. If the thermal motion of the molecular chain decreases, the heat resistance of polyamide will be significantly improved.

At present, high-temperature nylon is mainly used in automotive and electronic fields, which account for more than 90% of the total consumption demand of high-temperature nylon. Other applications include machinery, aerospace and military industry.

Benefiting from the development of downstream industries and the expansion of product applications, the global output of high temperature resistant nylon in 2020 was about 160000 tons. The price of high temperature resistant nylon is 2-3 times that of ordinary nylon, and the profit margin is large. The main reason is that the mainstream PPA products are mainly controlled by a few international giants, and the market demand is large, the competitive pressure is small, and the suppliers have strong bargaining power.

Overall, the high-temperature nylon Market in China's high-end applications is still occupied by foreign enterprises represented by DuPont, Solvay, DSM, etc. However, in recent years, domestic enterprises such as Goldilocks, jieshijie and Huaying new materials have been able to compete with international giants in some sub sectors through continuous R & D investment, and the market share of domestic high-temperature nylon has been increasing.

Shenzhen Huaying new materials Co., Ltd. is a high-tech enterprise committed to the R & D, production and sales of high-performance engineering plastics. Its main products include HPPA series, LCP series, PPS series, PA66 series, PBT series, PC series, etc.

At present, Huaying company has developed nearly 100 kinds of high-performance engineering plastics, and the modification fields include reinforcement, toughening, filling, flame retardancy, enhanced flame retardancy, halogen-free flame retardancy, wear resistance, antistatic, nano reinforcement, etc.
