Baling Petrochemical inaugurates domestic pilot test technology for special epoxy resins

Recently, Sinopec Baling Petrochemical Company first produced ultra-high-purity ortho cresol epoxy products. After being appraised by experts of Sinopec, the product has excellent performance and reaches the advanced level of similar international products, ranking first in the domestic market and being able to replace imports.
As a kind of special epoxy resin, o-cresol no-epoxy resin is widely used in the electronics industry because of its excellent thermal stability, mechanical strength, electrical insulation, heat resistance, and chemical resistance. Semiconductor devices, integrated circuits, and other packaging materials. At present, its production is mainly in the direction of high purity in foreign countries. Following the development of high purity o-cresol novolac epoxy resins, ultra-high-purity o-cresol novolac epoxy resins have been developed.
China began to produce epoxy molding materials in the early 1980s, but its grade was low. In recent years, with the development of China's electronics industry, the demand for o-cresol-formaldehyde epoxy resin is increasing, and the annual demand is nearly 4,000 tons. However, due to various reasons, the requirements for plastic materials have not been met.
As the largest epoxy resin manufacturer in China, Baling Petrochemical Company began research on ortho cresol epoxy resin in the 1990s. Based on the establishment of the first domestic epoxy resin experimental device for o-cresol, it is dedicated Research and development of this product.
The high-quality o-cresol novolac epoxy resin produced by Baling Petrochemical Co., Ltd. has the characteristics of low inorganic chlorine, low hydrolyzable chlorine, and low volatility. The technology is novel and creative, which indicates that the production technology of o- cresol novolac epoxy resin in China has reached the international advanced level, breaking the monopoly position of foreign companies in the Chinese market, and adjusting and optimizing the product structure of the company's epoxy resin.
