300 ® tubi plastici • plastic hoses POLYURETHANE TUBE Materiale dalle eccezionali caratteristiche meccaniche, questo tubo nasce per risolvere le problematiche legate ad applicazioni particolarmente gravose. TECHNICAL PROPERTY: Hardness Shore A Temperature working range Breaking Elongation Density (gr./cm3) Abrasion loss (mm3) Tensile strenght (N/mm2) 98 - 20°C 540% 1,18 55 120 +70°C (DIN 53504) (DIN 53479) (DIN 53516) (DIN 53515) TECHNICAL FEATURES: Excelent resistance at the abrasion Good resistance at the atmospheric effects Good process of becomming old High flexbility at the lowest temperatures Extremely endeavor resistance Very low “click” and “stress cracking” effects OTHER FEATURES: Tolerances: Colours avalaible: Packing: MAIN APPLICATIONS: Pneumatic, Robotic, agriculture, garage, etc. GENERAL NOTICES: 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.

Rolls in plastic film POLYAMIDE TUBE The polyamide is the most diffused material among the technical applications for its characteristics of flexibility and mechanical performances. CHARACTERISTICS: High mechanicl properies 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 Density Hardness Elongation at break Elastic modulus Working pressure Tolerances: Colours avalaible: Packing: TRIAL METHOD ASTM D-792 ASTM D-2240 ASTM-D638 ASTM D-790 - VALUE 1,03g/cm3 65ShD >300% 410MPa -40°C/+70°C O.D. +/- 0,1 mm Thickness +/-0,1 mm Light blue, black, red and neutral. 100 mt. Rolls in plastic film APPLICATION: 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. REFERENCE NORMS: ISO 1874 - DIN 73378 - DIN 74324 COPOLYESTER+POLYURETHANE 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. FEATURES: 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.

Internal diameter +/- 0,2 mm (+/- 0,3 from diam. 7,5mm). Colours available: See technical page xx Packing: 100 mt. Rolls in plastic film APPLICATION: 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. 180 dimensioni di ingombro e informazioni tecniche sono fornite a puro titolo informativo e possono essere soggette a modifica senza preavviso
