Adhesive Closed Cell EPDM Foam Tape

Adhesive Closed Cell EPDM Foam Tape and Roll for Waterproof Gaskets and Seals

Topsun adhesive closed cell EPDM foam tape is a weather-resistant sponge rubber foam material designed for waterproof sealing, air sealing, gasket foam blocks, HVAC seals, construction joints, automotive seals, equipment protection and custom die-cut foam tape applications. The closed-cell structure helps resist water absorption and supports reliable sealing performance under proper compression.

Closed cell EPDM foam rolls can be supplied with or without adhesive backing, and can be converted into rolls, strips, gaskets, pads, tapes, blocks and custom die-cut parts. Topsun can customize foam density, hardness, thickness, block size, roll size, adhesive type, release liner, strip width, gasket shape and packaging according to customer drawings, samples or application requirements.

Closed Cell EPDM Foam Roll Features

• Excellent weather resistance for outdoor sealing and industrial applications.

• Waterproof closed-cell structure with very low water absorption.

• Good thermal insulation performance for HVAC, construction and equipment protection.

What Is Closed Cell EPDM Foam Roll?

EPDM, or ethylene propylene diene monomer foam, is a mid-density closed cell sponge rubber material used in a wide range of industrial and commercial applications. It is valued for ageing resistance, durability, compressibility, thermal durability and sealing performance.

Closed cell EPDM foam provides shock insulation, sound insulation, moisture resistance, sunlight resistance and a wide operating temperature range. It is available in various thicknesses from 0.5mm to 40mm and can be processed into sheets, rolls, strips, tapes with or without adhesive, blocks, seals and gaskets.

EPDM sponge rubber is widely used in construction, HVAC, transportation, automotive, appliances and machinery as EPDM foam seals, gaskets, strips, tapes or sheets with or without self-adhesive backing.

The closed-cell structure helps create air and watertight sealing performance with suitable compression. It also helps reduce the build-up of bacteria and mold while improving long-term sealing reliability. Final sealing performance depends on density, hardness, thickness, compression ratio, adhesive backing and installation surface.

Custom Adhesive EPDM Foam Tape, Gasket and Strip Options

Topsun can supply adhesive closed cell EPDM foam tape in rolls, sheets, strips, gaskets, pads, blocks and custom die-cut parts. Available custom options include density, hardness, thickness, roll width, strip length, adhesive type, single-side or double-side adhesive, release liner, die-cut shape and packaging method.

For sealing projects, customers should confirm compression space, required sealing level, water exposure, outdoor UV exposure, working temperature, bonding surface, adhesive requirement, foam density, hardness, thickness and estimated quantity. These details help determine the correct EPDM foam grade and adhesive system.
