Thermiculite is comprised of exfoliated vermiculite to maintain integrity across a wide range of high temperatures. Unlike traditional graphite gaskets, which are susceptible to oxidation, Thermiculite gasket material ensures seal integrity even at significantly higher service temperatures.
The Flexitallic Novus range offers a selection of non-asbestos fibre materials designed to excel in demanding high-temperature and corrosive substance applications. These materials are specifically engineered to perform in environments where oils, fuels, and acids are present.
Flexitallic's SF product line features compressed fibre sheets combined with rubber-binding materials like NBR or SBR. This comprehensive range offers various fibre options, including glass, aramid, and carbon, ensuring long-term joint integrity across diverse applications, including dry and wet steam and hydrocarbons.
The SIGMA range is Flexitallic’s cutting-edge biaxially oriented PTFE material for applications dealing with aggressive chemicals, SIGMA outperforms conventional materials, ensuring superior sealing performance.
Below are some examples of the range and composition of Flexitallic materials that we commonly use in the gasket manufacturing process. Other materials are available. Please talk to our technicians for more information.
