Coru281 Black High Temperature Viton® Rubber 70° shore is a Viton® GRADE B. Grade B offers better chemical resistance than Viton® A with superior flexibility in higher heat applications. Our Viton B is an excellent choice for power stations where Sulfur Dioxide is present along with many other applications where a superior product, to the already impressive Viton® A, maybe required due to higher temperatures and or additional resistance to chemicals or oils.
N.B. Available in plain or self-adhesive backed tape (SAB) alternatives. Bespoke sheets and gaskets are available, as well as customised rubber strips. Email your enquiries to sales@coruba.co.uk.
