Hydrocarbon resin (PCH) is mainly used in the field of high-frequency and high-speed copper clad laminate production. Chinese companies have weak competitiveness.

Hydrocarbon resin, also known as hydrocarbon resin, or PCH for short, refers to a type of thermoplastic resin generated from the C5 and C9 fractions produced by petroleum cracking through pre-treatment, polymerization, distillation and other processes. The molecular weight of hydrocarbon resin is between 300-3000, which is a kind of oligomer, including butadiene styrene copolymer, butadiene homopolymer, styrene/divinylbenzene copolymer, etc.

According to the“2023-2028 Hydrocarbon Resin (PCH) Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research CenterIt shows that hydrocarbon resin has excellent dielectric properties, heat resistance, chemical resistance, miscibility, light stability, gloss, transparency and refractive index. It is a high value-added chemical industry product. It has broad application prospects in electronics, coatings, inks and other fields.

At present, in the electronic field, hydrocarbon resin has become one of the important electronic grade resins required for the production of high-frequency and high-speed copper clad laminates. Compared with other electronic-grade resins such as PTFE and LCP, hydrocarbon resins have lower cross-linking densities and molecular formulations, are widely available, are cheap and easy to obtain, and therefore, currently hydrocarbon resins have become the preferred choice in the field of high-frequency and high-speed copper clad laminates. Hot spots, the market has broad room for development.

High-frequency and high-speed copper clad laminate is an important substrate material required for high-frequency and high-speed PCB production. It mainly plays the role of interconnection, conduction, and insulation. It can be widely used in communication equipment, consumer electronics, automotive electronics, industrial automation, aerospace and other fields. Currently, under the background of the rapid development of emerging technologies such as 5G, big data, and the Internet of Things, the demand for high-frequency and high-speed PCBs continues to increase, which in turn drives the demand for high-frequency and high-speed copper-clad laminates and its important raw material hydrocarbon resin to continue to increase.

However, electronic-grade hydrocarbon resins also have shortcomings such as low expansion coefficient after curing, poor heat resistance, and low peel strength during the production process. The production is difficult and the technical barriers are high. Therefore, for a long time, global electronic-grade hydrocarbon resins have been dominated by American and Japanese companies with strong R&D capabilities, including Japan’s Asahi Kasei, Soda, Mitsubishi Gas Chemicals, Dainippon Ink, etc., and the United States’ Sartomar, CrayValley, Karton PolymersLIC and other companies.

my country’s hydrocarbon resin industry started late. Compared with leading international companies, local companies still have a large gap in R&D strength, large-scale mass production strength, product performance, etc., and are still at a disadvantage in global market competition. In the future Local companies also need to accelerate their pace to catch up with leading international companies. Domestic companies in the field of hydrocarbon resin R&D and production mainly include Sichuan Dongcai Technology Group, Qingdao Yisen New Materials, Tongcheng Chemical, Huaqi Chemical, etc.

Industry analysts said that Dongcai Technology is a leading company in the domestic hydrocarbon resin industry and the company has achieved breakthroughs Technical barriers have entered the stage of industrialized production. Generally speaking, hydrocarbon resins have relatively high technical barriers, and currently the number of domestic enterprises in this field is relatively small. In the future, as local companies continue to increase technology research and development, my country’s hydrocarbon resin industry will still have considerable room for growth.
