PU Hose or PVC Hose Which is Better?
TPU and PVC are both common plastic materials, and they each have unique characteristics and applications. To determine which material is better, it is necessary to choose according to the specific use needs and use environment. The following is a detailed comparison of TPU and PVC materials:
TPU is an elastomer material with superior performance, which has the advantages of high wear resistance, high mechanical strength, good processing performance, oil resistance, water resistance, mold resistance, regeneration, good utilization and long life. These characteristics make TPU hose materials have a wide range of applications in many fields. Such as automotive parts, soles, conveyor belts, etc., especially in products that need to withstand a lot of friction and wear, contact with grease and oils, and outdoor use. In terms of oil resistance, TPU can resist the erosion of various fats and oils, while PVC is relatively poor.
In terms of weather resistance, the weather resistance of TPU is better than that of PVC and can maintain better stability under harsh environmental conditions. However, TPU itself is not flame retardant, so it cannot be used in places with flame retardant requirements. And the price is expensive, from the economic point of view, it is not as good as PVC.
PVC is a commonly used plastic material, large price advantage, low processing difficulty, good stability, can be compatible with more required additives, flexibility can be adjusted, and a wider range of applications. It has the characteristics of corrosion resistance, heat resistance, flame retardant, mechanical properties, good insulation performance, plasticity, and environmental protection. The corrosion resistance of PVC makes it widely used in chemical industry, environmental protection and other fields. The heat resistance makes it have excellent performance in wire and cable, automobile, construction and other fields. The flame retardant gives it an advantage in construction, aerospace and other fields. In some specific application scenarios, some characteristics of PVC may be more suitable. For example, the corrosion resistance and flame retardancy of PVC may be more advantageous in some specific environments. However, the mechanical properties of PVC are far less than that of TPU. Moreover, PVC will produce toxic gases when it is burned, which will have a certain impact on the environment.
To sum up, TPU and PVC hose each have their own advantages and applicable environment, in the selection of materials, need to be selected according to the specific needs and environment. Therefore, it is not easy to judge which material is better.
