Material spiral: spring steel wire wall: pure polyester polyurethane (acc. to DIN ISO 4649 more abrasion-resistant in comparison to polyether polyurethane) wall thickness between spirals approx. 1.7 - 2.1 mm depending on DN Applications ● Protective Hose against mechanical wear ● Special hose for dry suction vehicles ● Light, flexible head hose | Properties ● highly abrasion-resistant ● good chemical resistance ● generally good UV and ozone resistance ● oil/petroleum-proof ● free of halogens and plasticizers ● gas-tight ● small bending radii ● high tensile strength ● mostly smooth inner lining ● optimum flow characteristics ● reinforced version of standard ● extremely flexible ● lightweight ●acc. to TRBS 2153 (Zone 20) for non- flammble dust/bulk solids for conductingelectrostatic charges when earthed at both ends of the spiral ● microbe-resistant ● antistatic, surface resistance < 10 Temperature Range ●-40°C to +90°C ● peaks to +125°C |
