Data from April 16 regarding Jilin Petrochemical’s production and operations reveals that sales of its newly developed EPDM rubber product, J-3100, surged in the first quarter. The company sold 1,258 tons, generating over 2 million yuan in profit and establishing the product as a new driver of earnings growth.
J-3100 was developed by Jilin Petrochemical to compete with imported products. It boasts excellent overall performance—including outstanding weather and ozone resistance—making it an ideal material for high-end applications such as automotive solid rubber strips, hoses, and molded products.
The domestic market for automotive solid rubber strips—which consumes 100,000 tons of rubber annually—has long been dominated by imports. For nearly a decade, Jilin Petrochemical’s technical team has focused on developing EPDM rubber specifically for this sector, conducting in-depth research to reduce odor and optimize molecular weight distribution. Several new technologies were successfully implemented in the company's new EPDM "D" unit, which commenced production in July 2025.
By fully integrating advanced technical expertise, the team overcame common industry challenges associated with dry-process EPDM production—such as issues with Mooney viscosity degradation and molecular weight control—thereby achieving lower odor levels and superior product quality.
During the product promotion phase, the company employed an integrated "production-sales-R&D-application" collaborative approach. Technical service teams took samples directly to downstream clients to address issues raised during trial runs—such as tensile strength, compression set, and vulcanization performance. The product's quality won widespread recognition, leading to the signing of procurement agreements.
