The thermosetting plastics industry is developing rapidly and the market size is expanding

Synthetic plastics can be divided into two types: thermosetting plastics and thermoplastic plastics. Thermosetting plastics refer to plastics that use thermosetting resin as raw material and are formed into finished products through a cross-linking and curing process. Thermosetting plastics are generally divided into two types: formaldehyde cross-linked type and other cross-linked type.

The molding process is a key link in the production of thermosetting plastics. At present, thermosetting plastic molding processes mainly include injection molding, compression molding, and transfer molding. The compression molding method, also known as the compression molding method, requires the raw materials to be heated and melted first, placed in the mold cavity, filled with pressure into the mold cavity, and finally made into thermosetting plastics through cooling, solidification, demoulding and other processes. The compression molding method has the advantages of small raw material loss, low equipment cost, and long mold service life, and is currently the mainstream molding process for thermosetting plastics.

According to the “2022-2027 China Thermosetting Plastics Industry Market Supply and Demand Research Consultation Report released by the Industrial Research Center, there are many types of thermosetting plastics. , Epoxy resin (EP), phenolic resin (PF), polyurethane (PU), urea-formaldehyde resin (UF), and silicone resin (SI) are more common products. Epoxy resin has the advantages of excellent electrical properties and stable mechanical properties, and is mainly used in the fields of printed circuit boards and electronic component packaging. In 2021, my country’s epoxy resin output reached 1.426 million tons, a year-on-year increase of 5.6%. Driven by market segments, my country’s thermosetting plastics industry has entered a stage of rapid development.

Thermosetting plastics are used in a wide range of applications, including adhesives, furniture, building materials, automobile manufacturing, integrated circuits, etc. At present, integrated circuits are the largest demand end for thermosetting plastics in my country. Thermosetting plastics are mainly used to make integrated circuit packaging materials. Thermosetting plastics with the advantages of high raw material purity, environmental protection, good thermal conductivity, and good flame retardant properties are ideal integrated circuit packaging materials. According to data from the National Bureau of Statistics, my country’s cumulative integrated circuit output reached 359.40 billion units in 2021, a year-on-year increase of 37.5%. As downstream market demand continues to grow, my country’s thermosetting plastics market continues to expand.

Changzhou Fangda Thermoset Plastics Co., Ltd., Shandong Dawn Polymer Materials Co., Ltd., Jiangsu Tianxin Chemical Co., Ltd., and Wuxi Chuangda New Materials Co., Ltd. are the main thermosetting plastics suppliers in my country. Changzhou Fangda Thermoset Plastic Co., Ltd. is a professional manufacturer of thermoset reinforced plastics. Its products are sold all over the country and exported overseas.

Industry analysts said that my country is the world’s largest producer and consumer of plastic products. As a segmented product in the plastic market, thermosetting plastics are widely used in many industries. widely used in the field. As market demand is gradually released, the scale of my country’s thermosetting plastics industry will further expand. In recent years, driven by leading enterprises, my country’s thermosetting plastics have gained competitive advantages and voice in the global market.
