Few rubbers can withstand extremely cold temperatures like EPDM. With an operating temperature as low as -50°C (with highs of +150 °C), EPDM is a solid choice in sub-zero temperatures. EPDM compresses well and is highly resistant to tears, abrasion and steam. Also, this durable synthetic rubber won't degrade under UV conditions. EPDM's all-round durability has seen it employed across a wide range of applications, including O-rings, automotive cooling systems, and as insulation in freezer room seals. For a low-cost sealing material that performs well in outdoor applications, EPDM is a good choice.
