巴陵石化实施SEPS新项目 Baling Petrochemical implements SEPS new project
Hydrogenated styrene/isoprene copolymer (SEPS) is produced by selective hydrogenation of styrene and isoprene copolymers. As a kind of high performance polymer material, SEPS fiber optic cable paste is irreplaceable in the field of fiber optic cable. It is a high cost performance lubricating oil viscosity index improver and a key material with high resilience or low hardness.
SEPSYH-4010 and YH-4020 have been used in fiber optic and cable filling paste in three SEPS products, which have excellent thixotropy, suitable viscosity and high-low temperature performance; SEPSYH-4051 is used in high-performance elastomers, with high tensile strength, good resilience, high transparency and other characteristics. The performance of the product is similar to that of similar products abroad, and some indexes are superior to that of similar products abroad, which fills in the blank in China.
Experts pointed out that the successful localization of SEPS is another important achievement in the development of high-performance, high-end and green synthetic rubber in China, especially in the application of high-performance lubricating oil and fiber optic cable industry. It is also a strategic significance for Sinopec to deepen the structural reform of supply side and cultivate innovative leadership, green and low-carbon industries. New growth points, the formation of new momentum, and constantly meet the growing needs of the people's lively practice of a better life. And the overall technology and products reach the international advanced level, which has significant economic and social benefits.
