PU pneumatic hose is a transparent pneumatic hose obtained by using polyurethane granules with an improved formula and high temperature extrusion and vulcanization. Models are 10 * 6.5, 12 * 8, 4 * 6. Polyurethane is made by adding organic diisocyanate or polyisocyanate with dihydroxy or polyhydroxy compound.
PU pneumatic hoses are mainly used in automated pneumatic systems to transport compressed air to control the movement of the cylinders to achieve the entire system work. Its characteristics are that the pipe body is soft and has good oil resistance. The characteristic is that when used on an air compressor, various kinds of grease may enter the pipe body or the surface is contaminated. After testing, its oil resistance is better than that of the nitrile-resistant oil-resistant hose.
The abrasion resistance coefficient of PU pneumatic hose reaches 0.2g / dm2, which can transport all kinds of particles, such as plastic particles, flour, all kinds of dust, and the anti-sticking ability of PU pipe is very good, which can prevent the pipeline from being blocked. , Saving production costs. The smooth inner wall can reduce the damping of gas and liquid flow and save power and energy. Excellent tear resistance, better tear resistance than ordinary rubber and plastic pipes, can be used in a variety of complex environments, the pipe body has good elasticity and longer service life.
PU pneumatic hose is non-toxic and odorless, and has excellent flame retardancy. It can be used in the food industry and underground mines. Good flame retardancy and fire resistance can be safely used in mines full of gas. Can be used to transport chlorine, acid and alkaline gases and liquids or solvents.
The working pressure of PU pneumatic hose can reach 2.8Mpa, the working temperature range is -40 degrees to 120 degrees, and it can be used in hydraulic pipelines or high temperature and high pressure environments. Pneumatic pipe, hydraulic pipe, garden water pipe, oil pipeline, water pipeline, petroleum exploration pipe, sandblasting pipe, peristaltic pump hose, etc.
