What are the advantages and disadvantages of TPU materials?
Advantages of TPU materials:
1. Excellent wear resistance, especially in the presence of water, oil and other wetting media, through the selection of raw materials and the adjustment of the formula, it can meet the different requirements of users for product performance.
2. The processing methods are diverse and widely applicable, and can be made into liquid rubber, casting molding, spraying, potting, centrifugal molding.
3. Oil-resistant, ozone-resistant, aging-resistant, radiation-resistant, low-temperature-resistant, good sound permeability, strong adhesion, excellent biocompatibility and blood compatibility.
Disadvantages of TPU materials:
1. Not resistant to strong polar solvents and strong acid and alkali media.
2. Not resistant to high temperature, easy to soften and deform at high temperature
3. Not resistant to ultraviolet rays, easily affected by ultraviolet rays and aging and deterioration.
4. Not resistant to acid and alkali, poor resistance to acid and alkali, easily eroded by chemical substances and lose performance.
5. The price that everyone cares about most: relatively high.
In response to the shortcomings of TPU materials, scientific researchers have been working hard to improve them and have achieved certain results. For example, the disadvantage of UV resistance can be delayed by adding UV absorbers and antioxidants. Other aspects are also being continuously improved, so let's wait and see.
