This commercial grade solid neoprene is a 70 Shore A polychloroprene elastomer supplied with a smooth, powder-free finish. It is a general-purpose neoprene sheet material suited for protective, isolation, and shock absorption applications across glazing, material handling, and industrial environments. Manufactured in the USA and compliant with both RoHS and REACH.
The material achieves a minimum tensile strength of 600 psi and minimum ultimate elongation of 200% per ASTM D412, with a specific gravity of 1.51 gr/cc and a service temperature range of -30°F to 200°F. Compression set is 80% max after 22 hours at 212°F per ASTM D395 Method B. Heat aging performance is characterized at 70 hours at 212°F per ASTM D573, with maximum allowable changes of ±15 Shore A hardness, ±30% tensile strength, and -50% elongation. Oil resistance per ASTM D471 (Oil #3 at 70 hrs at 212°F) shows a maximum volume swell of 120%.
Compliant with RoHS and REACH.
What differentiates this 70 durometer commercial grade neoprene from other durometer grades of neoprene?
At 70 Shore A (±5), this is a firm commercial neoprene grade suited for load-bearing isolation, setting block, and vibration damping applications where resistance to deformation under compressive load is required. Its smooth, powder-free finish makes it well suited for adhesive bonding applications and direct contact with glass or finished surfaces.
Why is hardness important for this neoprene application?
he 70 Shore A durometer determines the material's resistance to compression and deformation under load — a critical factor for setting blocks, isolation pads, and vibration damping applications. Too soft a durometer allows excessive deflection under load; too hard reduces compliance and energy absorption. The 70 ±5 Shore A rating positions this grade for firm, load-bearing isolation duties across the listed applications.
What is the service temperature range for this material?
The temperature range is -30°F to 200°F.
Is this material suitable for regulated environments?
Yes. This material is compliant with RoHS and REACH as stated on the TDS. No other compliance standards are specified.
How should this material be specified?
Specify grade (70 Durometer Commercial Grade Solid Neoprene / H-O part number 70DCGSNEOWB), thickness (1/16", 3/32", 1/8", or 3/16"), compliance requirements, dimensional tolerances, and finished format.
