Product Description
With decades of field-tested performance, EPDM sheet rubber has earned its place as a trusted benchmark for reliability. More than a generic elastomer, it is a professional-grade blend of EPDM and SBR relied upon by engineers and contractors worldwide for consistent, high-quality results. Widely used across industrial and commercial applications, it has built a strong reputation for weather resistance and dependable flexibility even in demanding environments. When project specifications demand a material with a legacy of resilience, this all-purpose rubber is the trusted standard of excellence.
Molecular-Level Resistance to UV, Ozone, and Oxidation: The durability of EPDM sheet rubber stems from its chemically stable, saturated polymer backbone providing a clear advantage over many unsaturated elastomers. Materials such as SBR, nitrile, and neoprene contain double bonds that are more vulnerable to ozone cracking and oxidation, while EPDM’s molecular structure remains stable under UV exposure and chemical stress.
As a result, it degrades more slowly in outdoor environments and maintains a more consistent compression set over time. For industrial and construction applications, choosing EPDM is a practical way to reduce maintenance demands and support long-term mechanical reliability.
Certified Quality for Demanding Applications: EPDM 70A rubber is manufactured to precise standards, delivering a professional-grade solution for industrial use. With a nominal Shore A hardness of 70, it provides a balanced combination of durability and flexibility. It is firm enough to resist abrasion while remaining pliable enough to create effective seals. Its performance is further reinforced by a 300% elongation capacity, allowing the material to stretch under pressure and return to its original shape without losing integrity. For applications that demand reliable manufacturing quality and proven performance, this material offers a dependable solution for long-term industrial use.
Availability & Customization: Backed by consistent supply and manufacturing expertise, EPDM 70A is stocked in widely used thicknesses, including 1/32″, 1/16″, 3/32″, 1/8″, 3/16″, 1/4″, 3/8″, 1/2″, 3/4″, and 1″. For specialized applications, custom sizes can also be produced to meet project requirements. This level of availability ensures that customers can confidently source the material they need without compromise.
Additional Benefits:
- 70A Industrial Hardness: Provides the ideal balance of firm abrasion resistance and flexible sealing
- Weather & UV Immunity: Saturated polymer structure prevents cracking and oxidation in harsh environments
- Industrial Standard: The go-to benchmark for consistent performance in high-stakes commercial and industrial settings
- Versatile Sizing: Available in ten thicknesses from 1/32″ to 1″ with full custom sizing options
