Gumlast™ 100% pure perfluoroelastomer (FFKM) parts have been put to the test by various industries in some of the most aggressive manufacturing and environmental conditions, and time after time Gumlast™ perfluoroelastomer parts have delivered.  We are proud that our US made perfluoroelastomer parts have offered such superior performance at a fraction of the cost when compared to well-known brands like Kalrez™.


Gumlast™ has successfully replaced well-known brands in high-temperature applications as well as Plasma etch and ALD deposition tools where seal integrity is paramount to line and die yields.  Gumlast™ 100% pure perfluoroelastomer (FFKM) seals deliver additional value in solar and flat panel display processing where the high cost of consumables created a barrier to entry to many players. Our Kratos™ gap compound has replaced Kalrez™ in CVD and etch processes with over 80% cost savings.

Food and Bio-Medical

Food, bio-medical and pharmaceutical industries require ultra pure components to meet the most stringent requirements. Our FDA and USP Class VI compounds have delivered such cleanness at a fraction of the cost. With one of lowest measured extractables in the industry, Gumlast™ 100% pure perfluoroelastomer (FFKM) parts are gaining momentum in ever-expanding market segments with a geographically diverse customer base.

Chemical and Hydrocarbon Processing

Gumlast™ perfluoroelastomer parts have been benchmarked at leading refineries against Kalrez™ in head-to-head product testing.  Our customers rely on the performance of Gumlast™ pure perfluoroelastomer (FFKM) seals to keep the fugitive emissions at bay while providing leak-tight performance of mechanical seals and control valves to protect people and assets from unplanned leaks.  Gumlast™ perfluoroelastomer parts provide sealing solutions in crude oil and natural gas productions where resistance to most aggressive fluids is key to a safe and successful operation.
