EPDM Foam
EMCO Industrial Plastics carries EPDM foam available in strip, sheet, roll, or custom gasket forms. EPDM is the most weather resistant foam, with a wide range of chemical compatibility, steam resistance, and good temperature range. Applications include anti-rattle and anti-skid applications, seals, flotation devices, and insulation. Available in semi-closed and closed cell types, with pre-applied single or double-sided Acrylic Adhesive backing options, and smooth or textured finishes.
Our EPDM 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 EPDM offering.
Material Highlights
- Great weatherability
- Excellent electrical insulating properties
- Outstanding heat and ozone resistance
- Good resistance to ketones, ordinary diluted acids, and alkalis
Material Grades
| Standard |
Made of industrial grade materials for general purpose use. |
Cell Types
| Closed Cell |
Prevents liquids and gasses from passing through. |
| Semi-Closed Cell |
Highly conformable like an open-cell foam, but forms a tight seal and prevents air, water, & fluids from passing through it like a closed-cell foam. |
