PU Hose is polyurethane tubing, which is made by the addition of organic di- or polyisocyanates and di- or polyhydroxy compounds. PU pipe is polyethylene plastic tubing, which is the most basic type of plastic that has excellent resistance to most household and industrial chemicals. So what is the difference between polyurethane and polyethylene tubing?
What is the polyurethane hose?
PU is the abbreviation of Polyurethane, the Chinese name is polyurethane. pu pipe is polyurethane pipe, it is made of organic diisocyanate or polyisocyanate and dihydroxy or polyhydroxyl compounds polymerization. Hose, etc., suitable for the general working pressure of liquid transmission in agriculture, food, medicine, civil engineering, fisheries, aquaculture, garden irrigation and other fields.
PU hose is mostly used for air hose, water hose and material conveying hose.PU material, i.e. polyurethane. With chemical resistance, light weight, high wear resistance, anti-dye, anti-expansion and other properties, the disadvantage is easy to aging. To a certain imported hose indicators of various parameters, for example, you can see that PU hose has a wide range of applications in material handling because of its wear resistance.
what is PU hose features?
1、good oil resistance.
2、good aging resistance.
3, resistance to tearing strength is three times that of natural rubber.
4、high elasticity, high elongation, high strength;
5、Good damping performance, smooth inner wall, small liquid resistance, low hydraulic loss;
6, beautiful appearance, small bending radius of the hose, non-toxic and tasteless, impact resistance, fatigue resistance, light and flexible.
7, good flame retardant, non-toxic and tasteless. Impact resistance, fatigue resistance, safe and reliable.
8, PU hose will not harden at very low temperature in winter and will not become soft and yellow at very high temperature in summer.
PU hose is widely used in glass industry, wood industry, steel industry, plastic industry, mining pits, shipbuilding industry, cement industry, etc. for mechanical transmission when the strong protection with the tube. At the same time, food-grade pipes can also be used in the food industry, pharmaceutical industry. It can better meet the requirements of various industries for transportation.
What is the polyethylene tubing?
PE pipe is the polyethylene plastic pipe, PE is the most basic plastic with excellent resistance to most domestic and industrial chemicals, PE pipe can be divided into low density polyethylene pipe, medium density polyethylene pipe and high density polyethylene pipe. It is used in building water supply, building drainage, buried drainage pipe, building heating and gas transmission pipe, electrical and telecommunication protection casing, industrial pipe, agricultural pipe, etc. There are two kinds of PE pipes, one is PE polyethylene pipe and the other is high density polyethylene pipe.
What is PE hose characteristics?
1. high density polyethylene non-toxic, tasteless, odorless white particles, melting point of about 130 ℃, the relative density of 0.941 ~ 0.960. it has good heat resistance and cold resistance, good chemical stability, also has a high rigidity and toughness, good mechanical strength. Dielectric properties, environmental stress cracking resistance is also good.
2. Corrosion resistance
Pe pipe can resist the erosion of a variety of chemical media, no need to do anti-corrosion treatment, and will not promote the growth of algae, bacteria or fungi, the service life of up to 50 years.
3. Strong physical properties
Medium density polyethylene performance between high and low density polyethylene, not only maintains the rigidity and strength of high density polyethylene, but also has good flexibility.
4. Economic and economical
The inner wall of pe pipe is smooth and does not scale. Compared with metal pipes, pe pipes can reduce the project investment of about one-third, can be coiled small diameter pipe, further reducing the cost of the project.
5. Good toughness
pe pipe is a high toughness pipe, the adaptability to uneven settlement and dislocation of the pipe foundation is very strong, good seismic resistance, suitable for use in areas at risk of earthquakes.
6. Simple construction
Pe pipe is light, easy to carry, easy to weld, few welding ports, when construction conditions are restricted, electrofusion welding can be used.
7. Good sealing
The pe pipe itself adopts fusion connection to ensure the interface material and realize the integration of joint and pipe. The tensile strength and burst strength of the interface are higher than that of the pipe body, which can effectively resist the circumferential stress axial stress generated by internal pressure.
8. Anti-cracking
PE pipe has low notch sensitivity, high shear strength of the segment of the different anti-scarring ability, resistance to environmental stress is very outstanding.
What is the difference between PU and PE tubing?
1. PE, polyurethane is widely used in thermoplastics for agricultural piping, ducting, hoses and creating custom piping solutions. While no plastic tubing product can universally handle all applications, there are certain differences that need to be considered for each application.
2. Compared to PU, polyethylene is less flexible but has good moisture resistance. Polyurethane tubing is used where flexibility, kink resistance and excellent abrasion resistance are required, such as cable sheathing, pneumatic controls, analytical instruments, etc.
3. And polyethylene tubing has high strength, good corrosion and chemical resistance, so it is suitable for municipal, industrial, marine, mining, landfill, pipeline and agricultural applications.
