6.8lbs Closed Cell EPDM Foam Roll

6-8 lbs Closed Cell EPDM Foam Roll

TOPSUN supplies 6-8 lbs closed cell EPDM foam rolls, blocks, sheets, strips, gaskets and adhesive foam tapes for sealing, cushioning, insulation and weather-resistant applications. EPDM foam, also known as ethylene propylene diene monomer foam, is a synthetic rubber foam material designed for long-term performance in outdoor and industrial environments.

Closed cell EPDM sponge foam has independent cells that help resist air, water, moisture, ozone and sunlight. It is commonly used for air-tight and water-tight seals, HVAC sealing, construction joints, automotive gaskets, equipment insulation, packaging protection and custom die-cut foam parts.

What Is Closed Cell EPDM Foam?

Closed cell EPDM foam is a mid-density sponge rubber foam made from EPDM rubber. The closed cell structure means the internal cells are separated by cell walls, helping the foam resist water penetration and air leakage. This makes it suitable for sealing against air, water, dust, vibration and weather exposure.

Compared with many general foam rubber materials, EPDM foam offers strong aging resistance, UV resistance, ozone resistance, flexibility, compressibility, recovery performance and thermal durability. These properties make it a reliable foam material for outdoor sealing, transportation, HVAC, construction, machinery and appliance applications.

Closed Cell EPDM Foam Roll Features

• Closed cell structure helps make the material resistant to air and water, making it suitable for air-tight and water-tight sealing.

• Outstanding aging resistance helps the foam maintain performance without becoming brittle over time.

• Durable and cost-effective for industrial sealing, gasketing and protection applications.

• Available in different hardness levels, including soft, supersoft, standard and higher-temperature grades.

• Good UV and ozone resistance for outdoor and weather-exposed applications.

• Good mechanical properties for cushioning, sealing, vibration absorption and gasket conversion.

• Wide operating temperature range for construction, automotive, HVAC and machinery uses.

Why Choose EPDM Foam for Outdoor Sealing?

EPDM foam performs well in outdoor sealing applications because it resists sunlight, ozone, moisture and temperature changes. It is widely used in construction, HVAC, transportation, automotive, general appliances and machinery.

The material can be converted into EPDM foam seals, gaskets, strips, tapes, sheets and blocks, with or without aggressive self-adhesive backing. For sealing projects, the correct density and compression rate are important because they affect sealing pressure, recovery and long-term durability.

Closed cell EPDM sponge rubber is commonly used to create air-tight and water-tight seals. Its closed cell structure also helps reduce moisture absorption and supports thermal sealing performance in physically demanding environments.

Closed Cell EPDM Foam Roll FAQ

What is closed cell EPDM foam roll?

Closed cell EPDM foam roll is a sponge rubber foam roll made from ethylene propylene diene monomer rubber. Its closed cell structure helps resist air and water penetration, making it suitable for sealing, gasketing, insulation, cushioning and outdoor weather-resistant applications.

What does 6-8 lbs EPDM foam mean?

6-8 lbs usually refers to the approximate foam density range expressed in pounds per cubic foot. In practical purchasing, buyers should confirm the required density, hardness, thickness and compression performance according to the sealing or cushioning application.

Is closed cell EPDM foam waterproof?

Closed cell EPDM foam has low water absorption and is commonly used for water-tight sealing. For demanding sealing projects, the final waterproof performance also depends on compression rate, gasket design, surface contact, adhesive selection and installation conditions.

Can EPDM foam be used outdoors?

Yes. EPDM foam is suitable for many outdoor applications because it offers good UV resistance, ozone resistance, weathering resistance and aging resistance. It is often used in construction, transportation, HVAC and exterior sealing systems.

What thickness can TOPSUN supply for EPDM foam roll?

TOPSUN can supply EPDM foam in a thickness range of 1-50 mm according to the product page. Custom thickness, width, adhesive backing and converted shapes can be discussed based on your application and order requirement.

Can EPDM foam roll be made into gaskets or sealing strips?

Yes. EPDM foam roll can be slit, cut, die cut, laser cut or adhesive-backed to make gaskets, sealing strips, foam pads, weather seals and custom industrial parts.

What applications are suitable for closed cell EPDM foam?

Closed cell EPDM foam is suitable for air and water seals, HVAC systems, construction joints, automotive gaskets, machinery pads, appliance seals, packaging protection, vibration absorption and adhesive foam tapes.

How do I choose the right EPDM foam density?

Choose the density based on sealing pressure, compression recovery, surface gap, load requirement and service environment. Softer foam is often used for low-compression sealing, while higher-density foam is preferred for stronger support and more demanding gasket applications.

Can EPDM foam be supplied with adhesive backing?

Yes. TOPSUN can provide adhesive-backed EPDM foam for tapes, strips, gaskets and stick-on sealing pads. Adhesive type should be selected according to the bonding surface, temperature, indoor or outdoor use and service life requirement.
