O-Ringe

The encapsulated O rings are made of silicone rubber or fluororubber core and wrapped in an FEP or PFA outer shell. This combination of a rubber's flexibility with a PTFE (Teflon) resistance to chemicals makes for strong, long-lasting O-rings. Encapsulated O rings can handle extreme temperatures, chemicals, and wear and tear very well.

In the world of industrial sealing technology, the choice of rubber material determines the performance, durability, and reliability of the final seal. From automotive engines to semiconductor vacuum chambers, each application requires a specific balance of chemical resistance, temperature capability, elasticity, and cost efficiency. This comprehensive guide introduces the 16 most common rubber materials used in sealing applications — detailing their core properties, temperature ranges, and...

In the semiconductor industry, where cleanroom integrity and uptime are mission-critical, selecting the right sealing materials can directly impact yield, process stability, and maintenance intervals. FFKM (perfluoroelastomer) O-rings are the gold standard for plasma etch and CVD (Chemical Vapor Deposition) chambers due to their unmatched chemical resistance and high-temperature capabilities. However, not all FFKM seals are created equal. This guide walks you through how to choose the optimal...

When selecting FFKM O-rings for semiconductor equipment, it’s not enough to rely on brand names or generic claims like “high purity” or “plasma resistant.” For engineers responsible for etch and deposition tools, quantifiable parameters are the key to ensuring seal longevity and process stability. This guide breaks down the 4 most critical parameters for FFKM material selection, based on material science, real-world data, and semiconductor industry best practices. Parameter 1: Thermal...

When industrial applications demand reliable sealing under harsh conditions, FFKM seals deliver exceptional performance. These specialized sealing solutions offer unique advantages that make them essential for challenging environments. What is FFKM? FFKM stands for perfluoroelastomer, a synthetic rubber with remarkable properties. This ffkm material combines the flexibility of traditional elastomers with chemical resistance similar to PTFE (Teflon). The result is a sealing material that...
