What is Micro-Cellular Rubber?

Micro-cellular rubber, also known as porous or sponge rubber, is a lightweight, elastic material manufactured from EPDM (ethylene propylene diene monomer) rubber. Its closed-cell structure provides excellent resistance to environmental factors such as weather, UV radiation, and fire. The material’s flexibility and resilience make it a versatile choice across various industries for sealing, insulation, and vibration-dampening applications.

This material is also available with adhesive backing on one side, enhancing ease of installation for specific applications.

Applications of Micro-Cellular Rubber

Automotive Industry

Micro-cellular rubber is widely used in the automotive sector for manufacturing gaskets, seals, and vibration-dampening components. Its ability to withstand extreme temperatures (from -40°C to +90°C) ensures reliability in engine bays and vehicle interiors.

Construction and HVAC

In construction and HVAC systems, this rubber is a preferred choice for thermal and acoustic insulation. It helps reduce noise levels and provides a barrier against air and water leakage in ducts and pipes.

Industrial Equipment

The material’s elasticity and durability make it ideal for covering sensitive parts, reducing vibration, and preventing wear and tear in machinery and equipment.

Consumer Goods

Micro-cellular rubber is also used in the production of durable padding, protective seals, and noise-dampening layers in various consumer products.
