Applications

Abrasion-proof suction and transport hose, especially suitable:

• for abrasive solids such as dust, powder, fibres, chips and granulates

• for gaseous and liquid media

• for public utility street cleaning vehicles

• for lawnmowers, grass sweeping machines and leaves exhaust

• for fodder transport

Properties

• medium-heavy model

• highly abrasion-proof (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)

• smooth interior

• optimized flow properties

• flexible

• high tensile strength and tear resistant

• food quality wall complies with: FDA 21 CFR 177.2600 and 178.2010, EC guideline 2002/72/EC incl. the latest amendment 2007/19/EC, German guideline XXXIX BfR polyurethane (see chapt. 14.5)

• good resistance to mineral oils and gasoline

• Good resistance to chemicals (refer to section 14.1)

• good resistance to UV and ozone (see chapt. 14.8)

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

• small bending radius

• kink-proof

• free of softener and halogen

• gas and liquid tight

• flame-retardant according to: UL94-HB

• conform to RoHS guideline

• 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
