What is the difference between PA and PU tubing

PU tube and PA pipe are common industrial pipe materials, and there are the following differences between them:

Material composition: PU tube is made of polyurethane material, while PA tube is made of polyamide (nylon) material.

Physical properties: PU pipe has good flexibility and bending properties, and wear resistance and impact resistance are also better; PA pipe has high strength and hardness, wear resistance and corrosion resistance are more prominent.

High temperature resistance: PA tubes can usually withstand higher temperatures and have better heat resistance. The heat resistance of PU tube is relatively poor.

Field of use: Due to its different physical characteristics, PU pipes are usually used in air pipes, hydraulic pipes and pneumatic pipes and other fields; The PA pipe is often used in automotive oil pipes, air brake pipes, hydraulic pipes, industrial pipes and other fields.

Therefore, when choosing to use PU tube or PA tube, it is necessary to make a suitable choice according to the specific use requirements and environmental conditions.
