Applications

Abrasion-proof and flame-retardant suction and transport hose, especially suitable:

• for applications, where flame-retardant hoses are demanded

• for high flow-rates of abrasive solids such as powder, chips and granulates

• for gaseous and liquid media

• for industrial vacuum cleaners, granulate conveying systems, printing machines, blowers and compressors

• as robust protection conduit

Properties

• conforms to the safety regulations of the German Wood Trade Association

• 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 with low weight

• increased pressure and vacuum resistance

• 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 (see chapt. 14.8)

• small bending radius

• kink-proof

• halogen free

• gas and liquid tight

• flame-retardant according to: UL94-V2, DIN 4102-B1, DIN 5510 part 2 (S2-S4, SR2, ST2)

• 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
