With the popularization of smart phones, more and more consumers have their own mobile phones. In order to prevent the damage caused by some accidents, such as collision and collision, mobile phone case seems to have become a necessary product to protect mobile phones. In addition to the pursuit of the protection of the case, the appearance of the case has also become an important consideration standard for consumers to choose the case. So in the vast production of mobile case raw materials in the competition, TPU is how to stand out?

First of all, TPU (Thermoplasticpolyurethanes) is mainly divided into polyester type and polyether type. To understand why TPU mobile case occupies a place in the mobile case market, we have to start with the characteristics of TPU:

1. Wide hardness range: Products with different hardness can be obtained by changing the ratio of TPU reaction components.

2. High mechanical strength: TPU products have outstanding bearing capacity, impact resistance and shock absorption.

3. Outstanding cold resistance: The glass transition temperature of TPU is relatively low, and it still maintains good elasticity and compliance at minus 35 degrees.

4. Good processing performance: TPU can be processed by common thermoplastic materials. At the same time, TPU and some polymer materials can be jointly processed to obtain polymer alloys with complementary properties.

5, oil resistance, water resistance, mold resistance; Good recycling.

A wide range of hardness and high load carrying capacity, impact resistance and shock absorption are exactly what we need to protect our mobile phones against shock and fall. Moreover, the advantages of TPU, such as high wear resistance, high strength, outstanding cold resistance, oil resistance, water resistance, mold resistance and good flexibility, also provide a solid foundation for the service life of TPU mobile phone case. TPU has excellent resilience, no deformation, good low temperature resistance, non-toxic and tasteless, environmental protection materials, with good color matching. TPU has low cost, convenient production and processing, short processing and molding cycle, and the secondary materials can be recycled and reused. Common hardness ranges from 85 to 95 degrees.
