Canrez® CP70WH12 is a 70 Shore A white, carbon-black-free FFKM compound engineered for high-purity O-rings and gaskets used in semiconductor, chemical, and precision industrial applications. It provides excellent chemical resistance and dependable thermal performance up to 230°C (446°F), with short excursions to 250°C (482°F). Designed for environments where carbon-filled materials are unsuitable, CP70WH12 offers superior cleanliness, stability, and resistance to plasma and aggressive process chemicals. Its low compression set and strong mechanical retention make it suitable for both static and dynamic sealing conditions.
CP70WH12 is extensively used in semiconductor manufacturing, as well as in chemical processing, automotive, ink, and paint applications requiring contamination-free operation. The compound’s near-universal chemical compatibility and consistent performance make it ideal for maintaining integrity in corrosive and high-temperature systems. This Canrez® formulation delivers high purity, long-term durability, and excellent sealing reliability where cleanliness and chemical resistance are critical.
