When working with chemical processing applications, there can be no half measures when deciding on the right polymer for mission-critical seals and components. Also, only the highest level of durability, chemical resistance and reliability are acceptable in the process. If you’re interested in finding out some of the most impressive and robust chemical resistant rubber, then continue reading our helpful guide.
Chemical resistant rubber materials
There are a diverse range of chemical resistant elastomers on the market, including chemical resistant O-rings, and other seals. Below is a detailed breakdown of some of the most impressive chemical resistant materials.
Perfluoroelastomers (FFKM)
When looking for the broadest chemical resistance in any elastomer, you would find Perfluoroelastomers. FFKM has an excellent sealing solution for demanding environments.
They include grades of high-temperature black 75 IRHD FFKM, and a white 75 IRHD for use with strong oxidising media, and hot aqueous solutions.
Polytetrafluoroethylene (PTFE)
Polytetrafluoroethylene (PTFE) rubber bonded seals are a cost-effective option for all kinds of chemical processing applications. PTFE also offers exceptional electrical insulation and dielectric strength.
In terms of performance within a broad temperature range of -30°C to +200°C, it can be classed as optimal. PTFE is also water resistant, extremely weatherable, has the lowest coefficient of friction of and solid, and is non-adhesive.
Fluoroelastomers (FKM/FEPM)
Fluoroelastomers offer greater thermal, oxidation and chemical resistance than most elastomers. With chemically inert Fluorine-Carbon bonds, it delivers a superb combination of high chemical resistance and low-temperature performance. FKM also boasts fantastic resistance to gas and liquid permeation, ozone, weatherability, and offers excellent mechanical properties.
Chemical resistance guide
When selecting polymers for custom rubber moulded solutions, you need to ensure that the product will be able to perform highly when faced with aggressive environments or harsh chemicals. Fortunately, a chemical resistance guide can help you pick out the right material.
The chemical resistance guide can help you point out specific chemical resistant materials quickly and easily, as well as discover which materials are not compatible with your selected chemical. The guide will also cross reference chemicals and find the recommended material for multi-chemical exposure.
