At Kriloha Ltd., we understand that in the world of high-purity chemicals and pharmaceuticals, “cleanliness” is a mechanical requirement. When you are moving life-saving medicines or aggressive reagents, the gasket must be more than a barrier—it must be invisible to the process. The Kriloha Pure PTFE Gasket is our solution for ultimate chemical neutrality. As a premier global supplier of high-performance seals, Kriloha Gaskets utilizes only premium-grade virgin resins to ensure our PTFE gaskets never leach, flavor, or react with your media.
Pure PTFE is a unique engineering plastic. It possesses a high molecular weight that gives it an almost “wax-like” conformability. When compressed between flanges, the PTFE flows into the microscopic peaks and valleys of the metal, creating a hermetic seal. At Kriloha, we utilize a precision Sintering and Skiving process to ensure our PTFE sheets have a uniform density and a smooth, pore-free surface. This prevents “wicking,” where chemicals could otherwise soak into the gasket material over time.
While Pure PTFE is legendary for its chemical resistance, it does possess a mechanical trait known as Cold Flow (creep). Under high pressure or temperature, the material tends to spread outward. To manage this, Kriloha recommends Pure PTFE primarily for lower-pressure systems or flanges with a “tongue and groove” design that traps the material. For higher-pressure applications, we offer “Modified” or “Filled” PTFE versions. However, for 100% chemical purity and FDA-mandated environments, the Kriloha Pure PTFE Gasket remains the undisputed industry standard.
