Greene Tweed’s Chemraz® SD625 is an 80 Shore A black perfluoroelastomer (FFKM) compound engineered for pharmaceutical, biotechnology, cosmetic, and food processing applications that require high purity, chemical inertness, and thermal stability. It offers near-universal chemical compatibility with a service temperature range of -20°C to 260°C (-4°F to 500°F), delivering reliable sealing performance in aggressive environments where FKM, silicone, and EPDM materials often fail. Chemraz® SD625 demonstrates exceptional steam-in-place (SIP) durability, maintaining sealing integrity through thousands of sterilization cycles. The material is manufactured within a fully traceable ISO 9001:2015 quality management system to support consistency and regulatory confidence.
Chemraz® SD625 meets extensive compliance requirements including FDA 21 CFR 177.2400(d), FDA Food Contact Notification (FCN) 245, USP <87> and <88> Class VI, 3-A 18-03 for dairy equipment, and ADI-free certification. It is commonly used in O-rings, gaskets, valve seals, and complex assemblies for hygienic and high-purity systems. This FFKM formulation combines broad chemical resistance, long-term steam stability, and regulatory compliance for critical life science and food-grade processing environments. Canyon Components offers equivalent FFKM materials designed to meet similar performance, compliance, and durability requirements for pharmaceutical, biotech, and food processing sealing applications.
