LOW WATER ABSORPTION

CLOSE CELL

Low-absorption closed-cell foam for weather sealing, insulation and moisture protection.

SUPERIOR MOISTURE BARRIER & WEATHER SEALING

Closed-cell foam features a non-porous cellular structure that effectively blocks water, air, and chemical penetration.

It is widely used for exterior weatherstripping, thermal insulation, and reliable moisture protection in harsh environments.

okin provides high-performance closed-cell foam in customized thicknesses and densities to meet your exact engineering needs.

FAQ

EPDM foam rubber is a flexible sealing and cushioning material made from ethylene propylene diene monomer. It offers strong resistance to weathering, ozone, UV exposure, moisture and temperature changes, making it suitable for indoor and outdoor applications.

Yes. EPDM foam is widely used for outdoor sealing because it maintains good flexibility and weather resistance under sunlight, rain, ozone and changing temperatures. It is commonly used in automotive, construction, HVAC, electrical enclosure and industrial equipment applications.

Closed-cell EPDM foam has low water absorption and provides effective resistance to moisture and water penetration. Its sealing performance depends on the foam density, cell structure, compression level and installation conditions.

Yes. EPDM foam can be supplied with single-sided or double-sided adhesive backing for easier installation. Adhesive options can be selected according to the mounting surface, operating temperature and required bonding strength.

Yes. We can customize EPDM foam by thickness, width, density, hardness, color and profile shape. Available processing options include sheet cutting, slitting, die cutting, adhesive lamination and custom extrusion. Samples and technical recommendations can be provided before mass production.
