The differences between PVC, rubber, and TPU layflat hoses

The primary differences among PVC, rubber, and TPU layflat hoses lie in their material characteristics, performance, and application scenarios:

Material characteristics
PVC (polyvinyl chloride): It belongs to the plastic material category, with strong weather resistance and corrosion resistance, but it is prone to hardening or brittleness at low temperatures.  ‌

Rubber: covers natural/synthetic rubber, with high elasticity and wear resistance, but complex processing and high cost.  ‌

TPU (thermoplastic polyurethane elastomer): combines rubber elasticity and plastic processability, is wear-resistant, oil resistant, and environmentally friendly, suitable for high-strength demand scenarios.  ‌

Performance Comparison
Temperature resistance: TPU has a wider temperature range (-40 ℃ to 120 ℃), while PVC has relatively poor temperature resistance (generally ≤ 60 ℃).  ‌
Elastic recovery: TPU has better elastic recovery ability than PVC and rubber, and is not easily deformed after long-term use.  ‌
Wear resistance: TPU and rubber are superior to PVC, suitable for frequent friction scenarios.
Typical applications
PVC: commonly used in industrial drainage and low-pressure drainage.  ‌
Rubber: commonly used for high temperature resistance and good elasticity.  ‌
TPU: Suitable for high-pressure and wear-resistant scenarios such as mining, oil fields, agriculture, etc.
