(Product structure ) inner layer rubber, enhancement layer, outside layer rubber
1. inner layer rubber: polyurethane and butyl rubber are the mainly material, and put in special reinforced material to make
mixed rubber .its colour is black and transparent. With high wear resistance, high toughness, high pressure, smooth, and so on.
The friction resistance of concrete Wipe, tube has the pressure transmission medium, wire protection from erosion effect.
2. enhancement layer: 4 layer of steel wire wound, the use of copper wire braided hose, bearing the work pressure
is the ordinary hose 3-4 Times, with a high degree of resistance, flex features superior performance, enhancing effect.
3. outside layer rubber: Black, smooth (wrapped), SBR/NR compound, anti aging, wear resistance.
(material ) natural rubber and steel wire
