A traditional rubber band is generally a short loop made of rubber and latex, commonly used to tie things together. Although the cost of rubber raw materials is low, because the manufacturing machine cost of rubber rubber bands is very high, and the rubber rubber bands themselves are easy to age, a product that replaces rubber rubber bands-TPU rubber bands has gradually appeared on the market.
So what are the advantages of TPU rubber bands?
1. TPU is the abbreviation of Thermoplastic Urethane thermoplastic polyurethane elastomer. so-called
Elastomer refers to a polymer material with glass transition temperature lower than room temperature, elongation at break > 50%, and good recovery after external force is removed. Its main advantages are: high wear resistance, strength, high cold resistance, outstanding oil resistance, water resistance, mildew resistance and good flexibility.
2. From the outside, the TPU rubber band can be made into a lot of color and transparency, and it is now more popular among users. The rubber band can not achieve that effect, the most transparent is very hazy, can not be completely transparent.
3. Compare the production cost of the two rubber bands. - Generally speaking, the cost of TPU rubber band extrusion production line is about 100,000 RMB, while the production cost of natural rubber rubber band extrusion production line is as high as several million RMB.
To sum up, the advantages of TPU rubber bands are much higher than that of rubber rubber bands.
