EPDM, Commercial Grade, 70A, 1/4" x 36", 5ft

EPDM 70A is a commercial-grade rubber material developed for reliable performance under continuous stress and exposure. Unlike conventional rubbers like nitrile or neoprene, which contain reactive double bonds prone to degradation, Rubber-Cal EPDM 70A is built on a saturated polymer backbone often enhanced by a durable EPDM/SBR blend. This chemical foundation makes EPDM 70A rubber virtually immune to the primary drivers of material failure, including UV radiation, ozone exposure, and oxidation. Rather than becoming brittle or losing its seal, EPDM 70A retains its molecular stability and dynamic resilience even when subjected to relentless weathers. At a nominal 70 Shore A durometer, this sheet rubber provides an ideal balance between surface toughness and mechanical flexibility. EPDM 70A is firm enough to withstand high-pressure sealing and load-bearing requirements, yet resilient enough to function as a superior vibration isolator. Its impressive 300% elongation capacity ensures that the EPDM can deform under stress and fully recover its shape without permanent set, even through repeated cycles of mechanical loading. This "shape memory" makes EPDM 70A the gold standard for protective liners and gaskets where consistent performance is critical. The SBR component in the blend helps bolster physical durability, ensuring the sheet rubber stands up to the rigors of construction and manufacturing. To ensure the material fits perfectly into your specific project requirements, EPDM 70A rubber is manufactured in a full range of standardized thicknesses from 1/32" to 1". This flexibility enables direct integration into maintenance systems and assembled components without additional processing. Ultimately, choosing Rubber-Cal EPDM 70A ensures a reliable, long-term solution for the most demanding physical and environmental challenges.
