FKM Compounds for Fuel and Chemical Industries
FKM Compounds for Fuel and Chemical Industries
Minnesota Rubber and Plastics offers a wide range of materials to meet the needs of fuel and chemical sealing applications. These compounds include a variety of FKM (fluorocarbon) materials, some of which offer more chemical resistance, improved cold temperature performance or heat resistance.
