O-Ring for Chemical Processing

Chemical Processing O-ring & Seal Materials

Perfluorinated (FFKM)
Fluorocarbon (FKM, VITON®)
PTFE

The substances used in the food and in the chemical process industries are identical in many cases, whether they are of natural origin or synthetically produced. Irrespective of their type and occurrence – be it in process media, in raw materials for products or in finished products – the materials for seals and engineered components used in production equipment coming into contact with diverse chemical substances have to meet specific purity requirements and be resistant to chemicals under the given process conditions. Purity and stability are therefore basic prerequisites for materials in the chemical process industry and the food industry.

Perfluoroelastomers (FFKM) provide the highest level of thermal and chemical resistance available, making them ideal for use in the most demanding chemical sealing applications. Optimized seals can also reduce fugitive emissions from valve applications in refineries and chemical plants, implementing the most chemically inert elastomer materials.
