Characteristics:
The S BLACKROCK+ R650 is a black natural rubber with a hardness of 60 Shore A, known for its excellent abrasion resistance.

Advantages:

• Excellent resistance to impact, tearing, and wear.
• Good resistance to aging and heat.
• Significantly reduces noise and vibration propagation.
• Protects against corrosion.
• Can be manufactured with an adhesive layer for cold vulcanization.
• High performance at low temperatures.

Applications:
Suitable for lining equipment such as hoppers, chutes, conveyors, and truck beds, especially at loading and unloading points of highly abrasive or aggressive materials. Applicable in industries like quarries, glassworks, construction, civil engineering, mechanical construction, and transportation.

Maintenance Recommendations:
Follow the usage instructions on the cleaning product packaging carefully.
