acid alkali resistant rubber hose

acid alkali resistant rubber hose This type of rubber hose is applied to machinery,ships and chemical industry where the circulating concentration of H2SO4and HCL solution is not more than 40%,NaOH solution is not more than 15%,and acid alkaline solution is equivalent to above concentration(except nitric acid NHO3).It is salt and seawater corrosion resistant. 1.Size:1"-12" 2.Max.length:40m 3.Delivery detail:depend on quantity 4.Sample:for free 5.Branding:as request 6.Applicable standard:HG2183-91 Technical parameters: 7.Anti-ozone aging:in the standard test chamber,concentration:50+/-5pphm,temperature:40+/-2°c,testing period:144t,without crack. 8.Heat-proof aging:in the standard aging chamber,temperature:100+/-1°c,testing period:72t,tensile change:not more than -20%,tensile stretch:not more than-40%. 9.Corrosion resistance:acid-alkali resistant. 10.Physical properties:tensile stretch of inner and outer rubber layer:≥300%,flexibility of hose is sound under -30+/-2°c for 5t,without craze crack or fracture after 180° bending over or doubling. 11.Structure: A.Inner layer of hose:blends of ethylene-propylene-diene monomer(EPDM0rubber and natural rubber(NR).
