Semi-aromatic polyamide (PPA) has broad application prospects and the production strength of Chinese enterprises is continuing to improve.

Semi-aromatic polyamide, also known as high-temperature nylon, referred to as PPA, refers to an engineering plastic formed by the condensation polymerization of aliphatic diamines and diacids and diacids and diamines containing benzene rings. Semi-aromatic polyamide has excellent heat resistance, creep resistance, dimensional stability, mechanical properties, fatigue resistance, aging resistance, electrical insulation properties, corrosion resistance, machining properties, etc., and can be widely used in electronics , automobiles, plastics, LED display and other fields. Currently, the common semi-aromatic polyamide grades on the market mainly include PA4T, PA6T, PA9T, PA10T, PA11T, PA12T, etc.

From the upstream of the industrial chain, the raw materials for semi-aromatic polyamides are mainly aliphatic diamines, diacids (butanediamine, hexamethylenediamine, decanediamine, etc.) and diacids and diamines containing benzene rings. Butanediamine is mainly used to prepare PA46 and PA4T. my country does not yet have the mass production capacity of this product. Only DSM has the mass production capacity in the world. Hexamethylenediamine is mainly used to prepare PA6T, and the localization level of its raw material adiponitrile is relatively low. Low; Decanediamine is mainly used to prepare PA10T, and the number of domestic production companies is small. Overall, the current development of my country’s semi-aromatic polyamide industry is still limited by insufficient supply of raw materials, and there is huge room for industry growth in the future.

From the downstream of the industrial chain, semi-aromatic polyamide has a wide range of applications. In the electronic field, it can be used as a heat-resistant material for electronic connectors, low-voltage connectors, connectors, coil bobbins and other heat-resistant components, thin-walled Product manufacturing scenarios; in the automotive field, it can replace thermosetting plastics in automotive parts manufacturing scenarios such as car hoods, fuel tanks, oil pipes, rolling bearing cages, engine brackets, etc.; in the LED field, it can be used as black and white materials for LEDs Display manufacturing scene.

According to the“2023-2028 Semi-aromatic Polyamide (PPA) Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center shows that electronics is the main application field of semi-aromatic polyamide. Benefiting from the rapid development of the domestic electronics industry, its market demand continues to increase and sales continue to increase. In 2022, my country’s semi-aromatic polyamide market sales will exceed 40,000 tons.

Semi-aromatic polyamide has high technical barriers. For a long time, my country’s market has been dominated by international companies, including BASF, DSM, Aymans, Mitsui, Kuraray, Sowell, etc. However, in recent years, driven by the continued growth of market demand, the number of domestic companies in the field of semi-aromatic polyamides has continued to increase, and their production capabilities have continued to improve. Industry analysts said that the main domestic semi-aromatic polyamide manufacturers include Jiangmen Dezhongtai Engineering Plastic Technology , Kingfa Technology Co., Ltd., Qingdao Sanli Bennuo New Material Co., Ltd., Jieshijie Group, Zhejiang Xinhecheng Co., Ltd., Henan Junheng Industrial Group, Guangdong Longjie New Material Technology, etc.
