Silicone Rubber

EMCO Industrial Plastics carries a great selection of Silicone rubber grades, available in strip, sheet, roll, or custom gasket forms. This formulation can withstand the highest temperatures and offers the lowest compression compared to our other silicone compounds. It is also made of FDA compliant materials for food, beverage, and pharmaceutical applications. Available with a pre-applied High-Temp Adhesive backing.

Our Silicone materials are available in thicknesses of 0.005” to 1/2”, including all standard iterations of inch and metric thickness measurements across this range. Continuous strips, rolls, and sheets are available in any width from 1/4” to 36”, and lengths up to 150’. In-house CNC gasket cutting, machining, and waterjet cutting capabilities promote tight tolerances, repeatable accuracy, and rapid part development across our entire Silicone offering.

Material Highlights

FDA compliant for food, beverage, and pharmaceutical applications
Excellent weathering properties
Good chemical stability and flame retardancy
Superior resistance to heat and cold

Material Grades

Food	Meets FDA CFR 117.2600 food grade standard. Commonly used in food, beverage, and pharmaceutical processing applications.
Fabric Reinforced	Nylon and Polyester inserts help withstand high stress and frequent flexing. Commonly used for flange gaskets, diaphragm packing, or in heavy-compression applications.
Metal Detectable	Contains metal fillers which allow the rubber to be picked up by metal detection systems should they tear or fall into the process stream.
USP Class VI	A high purity requirement, permitting the material to be used in medical devices.
