Material Families

Three Proprietary Material Families

Every compound in our range is developed, tested and qualified in-house — three material families engineered to match distinct temperatures, chemical media and operating pressures, so you never have to compromise on performance.

Vertex Elastomers

HIGH-PERFORMANCE ELASTOMERS — FKM, FFKM, FEPM/AFLAS®, Fluorosilicone, HNBR

When standard elastomers fail, Vertex takes over. Our FFKM, FKM, FEPM/AFLAS® and HNBR compounds are engineered for aggressive chemical media, extreme temperatures and demanding oil & gas service — qualified to NORSOK M-710 and NACE TM0187 for rapid gas decompression and sour service.

FFKM Perfluoroelastomer O-Ring
Featured Capability

Experts in Manufacturing High-Performance FFKM O-Rings

FFKM — Perfluoroelastomer — O-rings are the last line of defense when conventional elastomers fail. ISMAT’s Vertex F Series delivers a fully fluorinated structure engineered for near-universal chemical resistance against acids, amines, steam and aggressive hydrocarbons, with minimal compression set and low outgassing even in vacuum.

Backed by a dedicated FFKM production facility and 40+ years of sealing expertise, our FFKM O-rings are trusted in oilfield, aerospace, semiconductor and reactor applications where zero downtime isn’t optional — it’s the requirement.

WE SOURCE COMPOUNDS AND MATERIALS THAT MEET GLOBAL STANDARDS

A seal is only as good as the material behind it. ISMAT sources and qualifies every compound to meet global industry benchmarks — ISO 9001, IATF 16949, API 6A and NORSOK M-710 — before it ever reaches production.

With a safety stock of 4,000+ custom molds and 10+ elastomer families ready to deploy, our technical team turns raw material expertise into sealing solutions that hold up in the field, not just on paper.

ENGINEERING THE SEALS OF TOMORROW

Behind every ISMAT seal is a team that doesn’t just manufacture — it problem-solves. Our in-house R&D engineers work directly with clients to understand the exact conditions a seal has to survive, then develop a compound to match, rather than pulling from a generic catalog.

From nuclear gamma radiation resistance to compounds rated for –65°C to 320°C, our R&D team turns real-world engineering challenges into sealing solutions built to perform today — and hold up for decades to come.
