High flexbility at the lowest temperatures. Good resistance at the atmospheric effects. Good ageing process Extremely endeavor resistance. Very low “click” and “stress cracking” effects. Tolerances: Outer diameter +/- 0,1 mm Thickness +/-0,1 mm Available colours: Light blue, Red, Black, Green, Yellow, Neutral, Grey, Cristal blue, Cristal Packing: 100 mt. Rolls in plastic film Pneumatic, Robotic, agriculture, garage, etc. Polyurethane tube material has excelent mechanical features and it is particularly addressed to mostly solve the heavy applications. Anyway polyurethanes, althoughthey are much resistant at the endeavor and at the flexion stress, trend to keep heat when working with continuous variable pressure and in case of high atmosphere temperature it could bring to the swelling or breaking of the tubing itself, specially on sizes 8x6, 10x8, 14x12. Polyurethane is normally also resistant to ozone, hydrocarbon, oils and greases, fuel and moderate chemical solutions. It is not, or very low, resistant to concentrated acids, ketons, esters and clhloride hydrocarbons. The int. x ext. diameter, material type and batch number are marked on the tube for traceability. Each batch of material is accompanied by a certificate of conformity. POLYURETHANE TUBE The polyamide is the most diffused material among the technical applications for its characteristics of flexibility and mechanical performances. Characteristics: Application: Reference norms: High mechanicl properties to traction and to continuous & alternate flexion, notable flexibility, good stability to heat, notable resistance to ageing, law water absorption, notable resistance to hydrocarbons and oils and good inertness to chemical agents. Mechanical/physical properties Trial method Value Density: ASTM D-792 1,03g/cm3 Hardness : ASTM D-2240 65ShD Elongation at break: ASTM-D638 >300% Elastic modulus: ASTM D-790 410MPa Working temperature: - -40°C/+70°C Tolerances: Outer diameter +/- 0,1 mm Thickness +/-0,1 mm Available colours: Light blue, black and neutral. Packing: 100 mt. Rolls in plastic film This kind of material is particularly indicated for the realization of tubing for pneumatic, robotic, steel, industrial machineries, ecc..., when there is the necessity of notable flexibility. ISO 1874 - DIN 73378 - DIN 74324 POLYAMIDE TUBE The “coex”, copolyester coated with polyurethane, is a material that has made mits entry into the pneumatic applications in the recent years, in particular to meet the needs of applications and availability. Today is a good alternative for both, technical and economic reasons, to the tubes storically used. Characteristics: Application: Very high flexibility also at low temperatures, excellent elastic return, low sensibility to “click” and “stress cracking” effect, excellent resistance to abrasion, good resistance to atmospheric agents, good aging, extremely resistant to fatigue, good chemical resistance, excellent resistance to cut and lubrication oil at low/medium temperature. Mechanical/physical properties Hardness: Water absorpion: Density: Elongation at break: Flexural elastic modulus: Abrasion loss: Break resistance: Working temperature: Trial method DIN 53505 - ISO868 a 23°C 50% r.h.

Internal diameter +/- 0,2 mm (+/- 0,3 from diam. 7,5mm). Available colours: See technical page 197 Packing: 100 mt. Rolls in plastic film Tubes made with this row material have all the credentials to fit in pneumatics, agriculture, in general when is required resistance with grease, emulsiifed oils, lubrication. The use with continuous pulsating pressures can create heat accumulation. POLYURETHANE TUBE/COPOLYESTER Plastic hoses Series AC
