Garlock EPDM Rubber (390600) 3mm(T) 1200mm(W) 70+/-5 SHORE A

EPDM (Ethylene Propylene Diene Monomer) rubber is a versatile synthetic elastomer known for its superior durability, flexibility, and weather resistance. In comparison to other elastomers like nitrile, EPDM rubber is much more superior in its outdoor resistance properties. The material is formed by combining ethylene, propylene, and diene monomers through vulcanization, creating a chemically stable polymer that can withstand harsh environments while maintaining structural integrity.

One of the standout properties of EPDM rubber is its excellent resistance to ultraviolet (UV) radiation, ozone, and oxygen. This makes it ideal for outdoor applications as it does not degrade under prolonged exposure to sunlight. Its resistance to weathering and aging ensures a long operational lifespan, even in challenging conditions. Additionally, another essential feature of EPDM that makes it suitable for outdoor applications is its moisture resistance. Closed Cell EPDM foam, with its tightly-knit air pockets, prevents permeation of water and other liquids, offering an absorption rate of less than 5%. This moisture resistance is particularly beneficial in applications requiring waterproofing, such as roofing membranes and weatherstripping.

In terms of cold and heat, EPDM rubber sheets are highly resistant to extreme temperatures, with EPDM temperature rating typically ranging from -40°F to +200°F. This wide temperature rating makes it suitable for applications such as weatherproof seals, membranes, and industrial gaskets which are subjected to extreme climates.

EPDM rubber chemical resistance is another crucial property to note. It exhibits excellent compatibility with polar substances such as water, alcohol, and alkalis while being less resistant to non-polar substances like oils and hydrocarbons. This makes EPDM rubber sheets ideal for industrial applications involving water-based or alkali-based chemicals, as they can resist deterioration and maintain structural integrity over time.

The mechanical properties of EPDM rubber also stand out as it has a high tensile strength, low compression set, and excellent flexibility, allowing it to absorb shocks and vibrations effectively. Solid EPDM rubber sheets and rubber strips, for example, are commonly used in heavy-duty applications where durability is essential. Meanwhile, the closed cell EPDM foam variant offers compressibility and resilience, making it suitable for sealing applications.

In terms of adaptability, EPDM rubber types range from solid to sponge, each serving different needs. Solid EPDM is dense and durable, and it is widely used in applications requiring robust resistance to weathering, ozone, and UV exposure. On the other hand, EPDM foam strips and sheets offer compressibility and sealing properties, making them ideal for creating seals in HVAC systems, weatherstripping for doors and windows, and vibration-damping pads. The material also comes in various EPDM sizes, catering to specific industrial requirements.
