Abrasion resistant polyurethane substratum. External reinforcement spiral in rigid anti-impact and anti-crush PVC. The principal characteristic is the extremely high
level of resistance to abrasion of the polyurethane layer, combined with the great flexibility conferred by the special super-elastic formula. 
Excellent resistance to atmospheric agents, aging and most chemical products.
Temperature range: -25°C - +60°C.
Applications: for particularly heavy duty applications, where great resistance to abrasion is required. Indicated for delivery or suction of cement, grains, sand, crushed stone, cement, etc.
Colour: outside grey with yellow spiral, inside red.
