Buna-N / PVC Foam
EMCO Industrial Plastics carries Buna-N / PVC foam available in strip, sheet, roll, or custom gasket forms. Buna-N/PVC foam exhibits excellent impact absorption and good chemical resistance properties. Available in a semi-closed cell type, also known as crushed-cell foam, with pre-applied Acrylic Adhesive backing options, and a textured finish.
Our Buna-N / PVC materials are available in thicknesses of 1/16” to 1”, 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 54”, and lengths up to 40’. In-house CNC gasket cutting, machining, and waterjet cutting capabilities promote tight tolerances, repeatable accuracy, and rapid part development across our entire Buna-N / PVC offering.
