TOMBO™ No. 2675-S2

BLAZER™ O-ring - S2
BLAZER S2 is a perfluoroelastomer (FFKM) that shows stable sealing performance in environments with high-temperature steam and nucleophilic agents. It is a product with significantly improved steam resistance, rapid decompression properties, and crushing properties thanks to Nichias’ newly developed, original cross-linking agent and its proprietary mixing technologies.
 

Features

Heat resistance guide: 320°C
It is perfect for sealing against a wide range of chemical solutions that were difficult to use with conventional FFKM and FKM such as hot water, steam, amines, esters, ethers, ketonic acids, bases, hydrocarbons, and chlorinated solvents.
It is also suitable for use in environments that undergo rapid decompression.
A material that is not susceptible to compression failure at high temperatures.

Applications

Sealing such as for valves, pumps, turbo equipment, coating machines, centrifuges, mixers, analysis equipment, and reactors
