Fillers That Improve PTFE’s Performance
By Doug 30 Jun, 2022
PTFE was discovered in the 1930s as an accidental byproduct of chlorofluorocarbon refrigerant production. It’s a synthetic compound consisting wholly of carbon and fluorine — a fluorocarbon. Its many unique properties make it highly attractive as a seal material. It possesses one of the lowest friction coefficients of any known material, is nearly 100% chemically […]
Cantilever V-Spring
By Doug 19 Apr, 2022
Shortly after the discovery and use of PTFE as a seal material, the need for a secondary energizing method became apparent.  Unlike rubber or urethane which possess elastic and spring-like properties, PTFE will not return to its original state once deformed. This is obviously not a desirable trait for sealing material, especially in dynamic sealing […]
