Applications

Abrasion-proof suction and transport hose, especially suitable:

• for public utility street cleaning vehicles

• for fodder transport

Properties

• vibration resistant

• heavy model

• highly flexible and compressible

• abrasion-proof

• extremely abrasion-proof with reinforcement underneath wire and narrow hose pitch (abrasion resistance about 2.5 to 5 times better than most rubber materials and about 3 to 4 times better than most soft PVC´s)

• flow-optimizing exterior folds

• flexible with low weight (in comparison with rubber hoses)

• high tensile strength and tear resistant

• microbe and hydrolysis resistant

• good resistance to mineral oils and gasoline

• Good resistance to chemicals (refer to section 14.1)

• good resistance to UV and ozone

• very good low temperature flexibility (better than comparable ester-polyurethanes)

• kink-proof

• free of softener and halogen

• according to TRBS 2153 (formerly BGR 132): capable of electro-static discharge by grounding the spiral, recommended for many applications with the exception of inflammable bulk materials

Construction
