The inner wall types of rubber industrial hoses
Wear proof
TPU hose Taber wear value is 0.35-0.5mg, which is the smallest among plastics. Besides, add lubricant can reduce friction, thereby further improve wear ability.
Tensile strength
The tensile strength of TPU is 2-3 times that of natural rubber and synthetic rubber. The tensile strength of polyester TPU is 60Mpa and the elongation is 410%. While tensile strength of PU TPU is 50Mpa, elongation 550%.
Oil proof
The oil resistance of TPU is superior to that of nitrile rubber. What’s more, it has long oil proof life.
Low temp, weather and ozone proof
The weather and aging resistance of TPU is superior to natural rubber. Thus it has special uses in the aerospace.
Food medical hygiene
Medical TPU is more and more widely used. Such as blood vessel, ureter, and infusion tube. TPU does not contain enhancers. Besides, it is non-toxic and odorless. Thus it is also a good choice for the food industry. For example, it can transfer milk and juice.
Hardness range
The hardness of TPU is 10A-80D. It remains press property below 15A. While it still remains elasticity when the hardness is above 85A. This is what others do not have. So TPU has high load support capacity and good suction and discharge effect.
