Specialised Material Certifications & Key Properties
NORSOK M-710 Approved Compounds (Oil & Gas)
TSL offers high-durometer FFKM compounds specifically tested and qualified under NORSOK M-710 specifications. Designed for severe petroleum exploration, completion equipment, and subsea valves, these grades resist Rapid Gas Decompression (RGD) and high-concentration Hydrogen Sulfide exposure.
Ultra-Pure Semiconductor & Vacuum Grades
For semiconductor manufacturing, wafer handling tools, ALD, and PVD processes, TSL supplies high-purity non-pigmented white FFKM grades engineered to eliminate filler-induced particulation and outgassing under high-vacuum plasma environments.
Critical Industry Applications
- Chemical Processing: Pumps, valves, reactors, mechanical seals, and analytical instruments handling concentrated acids, alkalis, solvents, and oxidisers.
- Oil & Gas (Upstream & Downstream): Downhole tools, exploration equipment, Christmas trees, and high-pressure compressors needing NORSOK M-710 compliance.
- Semiconductor & Electronics: Wafer processing chambers, plasma etch equipment, chemical vapor deposition (CVD), and vacuum isolation valves.
- Pharmaceutical & Biotechnology: Clean-in-place (CIP) and steam-in-place (SIP) processing lines requiring non-contaminating, validated process seals.
Why FFKM?
FFKM (Perfluoroelastomer) O-rings provide exceptional resistance to aggressive chemicals, extreme temperatures and demanding process environments. They combine the chemical resistance associated with PTFE with the flexibility of an elastomer, helping reduce downtime and extend service life.
