High Performance Sealing Solutions for Chemical Processing Applications
Zhejiang Jiacheng New Material Co., Ltd. (SJK for short) supplies a wide range of sealing materials to meet the needs of the chemical processing industry. These include materials that meet a variety of international standards, including FDA and USP Class VI standards for the manufacture of active pharmaceutical ingredients (APIs).

When high specification materials are required to withstand harsh chemical environments and extreme heat, Eastern Seals offers a variety of materials to suit each unique application. These include FKM, FFKM, FEP, HNBR, Viton GLT and Viton B.
Due to the variety of markets in the chemical processing industry, a variety of high performance materials are required to meet the demands for superior chemical sealing, reliability and long service life. Factories around the world benefit from the company's in-house technical team, who can identify the best sealing solution for each process.
Perfluoroelastomers (FFKM) have excellent chemical and thermal resistance, making them ideal for the harshest chemical process sealing applications. FFKM helps resist many aggressive chemicals and extends operating range in extreme high temperature environments.
Encapsulated o-rings (FEP and PFA) are recommended when standard o-rings do not have sufficient chemical resistance for the application and solid PTFE o-rings do not possess the resilience for a reliable, long-term fluid seal. They have Viton or silicone cores, but spring versions are also available for cryogenic applications.
With over 30 years of experience in the sealing industry, SJK provides the chemical processing market with sealing solutions that last longer, require less maintenance, and have the lowest cost of ownership. The company also offers full traceability - an ideal factor for any critical application.
