What is the classification and difference of the pu tube?


Fiber reinforced hoses are also known as: reticulated tubes, braided tubes, etc., mainly used in high-end food, make-up, medicine, etc., because the inner fiber line is named fiber reinforced hose.

Structure: Inner core TPU reinforced layer: fiber woven outer skin: TPU

Classification: Fiber reinforced hoses are divided into: fiber reinforced polyurethane hoses and fiber reinforced nylon hoses

pu tube

(1) Fiber reinforced polyurethane hose (XPU)

Features: Smooth appearance, small bending radius

Performance: High strength, high modulus, high elasticity, tear resistance, solvent resistance, oil resistance, weather resistance, and the performance of rubber and plastic. Its outer diameter, bending radius and weight are all the same diameter inner diameter rubber tube. 1/2-1/3, very convenient for process design and manual installation

Uses: High-pressure, low-pressure hoses are mainly used in high-pressure hoses, brake oil pipes on machine tools, automobiles, construction machinery, motorcycles, pneumatic instrument lines in industrial automation such as petroleum, chemical, pharmaceutical, smelting, etc.

(2) Fiber reinforced nylon hose (XPA)

Structure: Inner core nylon (XPA) reinforcement layer: Fiber braided Skin: Polyurethane (PU)

Features: Smooth appearance, small bending radius

Performance: High strength, high modulus, high elasticity, tear resistance, solvent resistance, oil resistance, weather resistance, and the performance of rubber and plastic. Its outer diameter, bending radius and weight are all the same diameter inner diameter rubber tube. 1/2-1/3, very convenient for process design and manual installation

Uses: High-pressure, low-pressure hoses are mainly used in high-pressure hoses, brake oil pipes on machine tools, automobiles, construction machinery, motorcycles, pneumatic instrument lines in industrial automation such as petroleum, chemical, pharmaceutical, smelting, etc.

Through the involvement of our company in this industry, another PVC fiber reinforced pipe has not been attributed to this type. Its structure is also PVC inside and outside, and the middle is fiber woven layer. Because the raw material cost is lower than nylon and PU, it still exists in China. Certain market. However, our main product is high quality PU yarn tube, which belongs to the above XPU category, PVC series is not considered.

The reasons are as follows:

A. TPU material itself is an environmentally friendly product, and the current international environmental assessment requirements for PVC are more and more complex;

B. In terms of product performance, TPU fiber clamping tube Dongguan Zhuoyi has matured to use softer TPU to produce high-pressure hose, so it is very beneficial for customers with low temperature requirements. Under sub-zero conditions, TPU is more than PVC. More soft;

C. The Taber value of TPU is the lowest among all plastics, which means that the TPU has the lowest wear value under the same conditions, so it is a good choice to use TPU fiber reinforced hose for daily drag and stretch.
