The black SBR rubber sheet is 70 Shore A and has a smooth finish. SBR (styrene butadiene rubber) is a synthetic rubber that provides good abrasion resistance. A hardness measurement of 70 Shore A means the material has a hard surface for good penetration and wear resistance.
Rubber is a strong, flexible material that provides good insulation and shock absorption. Some types of rubber may be weather or chemical resistant and withstand high temperatures. Wear resistance is the degree to which the rubber resists abrasion. Hardness is measured with scales Shore D, Shore OO, and Shore A, which is the most common scale. A higher number means the material is harder and more resistant to penetration. A lower number means the material is softer and more flexible. Tensile strength, used to indicate the material’s overall strength, is the peak stress it can withstand before it breaks.

Styrene butadiene rubber, commonly referred to as SBR, is a tough and resilient synthetic rubber material. It is so durable that it is a common rubber material used in the production of vehicle tires. Synthetic SBR is also highly resistant to damaging outdoor factors, including UV rays and ozone, allowing it to be an excellent indoor/outdoor rubber.
Rubber-Cal’s 70A durometer SBR sheet is one of the toughest rubber sheets we offer! The high durometer rating of this rubber sheet makes it an extremely durable rubber sheet that is often used for physically abrasive applications. Due to its hardness, flexibility is limited, but the rubber sheet makes up for its lack of flexibility in toughness.
A 70A SBR sheet is often used in heavy-duty applications due to its superior toughness. The high durometer rating makes this SBR sheet ideal for highly abrasive applications, such as conveyor skirting, belt wipers, blast curtains, bumpers, and street sweeper and snowplow blades. Not only will a 70A SBR rubber sheet protect surfaces, but it will also protect machinery in rough physical conditions.
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
