Abra-Super® and Abra-Super® Pro
Mining & Aggregate Rubber

Abra-Super® and Abra-Super Pro®

RM Biltrite™ Abra-Super® Heavy Duty Anti-Abrasion Rubber is compounded with premium natural rubber for maximum abrasion, impact, and corrosion resistance. Pure natural rubber has inherently high strength, resilience, and abrasion resistance, making it an excellent material for wear-heavy environments. Abra-Super® products are internationally tested to withstand handling rough materials in the mining industry and other tough environments. Their high tensile strength, greater elasticity, and excellent wear-resistance result in unmatched performance. Available with 1 or 2 sides sanded and/or 1 side with neoprene bonding layer.
