Currently on the market a wide range of rubber bands. The traditional rubber band is generally made of a rubber and latex short laps, usually used to tie things together. Although the low cost of the rubber raw material, but the manufacturing cost of the machine because of the very high rubber rubber band, rubber band itself is very easy and the aging of the rubber, so the market gradually comes out to replace the rubber band rubber products -TPU / TPR rubber band.
So TPU / TPR rubber band embodies the advantages Where is it?
1. Speaking from TPU rubber band material. The main material TPU / TPR rubber band is TPU and TPR. TPU is referred Thermoplastic Urethane thermoplastic polyurethane elastomer. The so-called elastomeric means glass transition temperature below room temperature, elongation at break> 50%, after removal of the external force better resilience polymer material. Its main advantages are: high wear resistance, high strength cold prominent oil and water resistant to mold good flexibility.
2. From the outside TPU / TPR rubber bands, TPU / TPR rubber band can be made a lot of color, transparent feel, now more widely welcomed by users. The rubber rubber band can not achieve the kind of results, the most transparent are very hazy, do not completely transparent.
3, compare the two kinds of rubber bands of production costs. Generally TPU / TPR rubber band extrusion line costs in more than one hundred thousand yuan, while the natural rubber rubber band extrusion line production costs as high as several million yuan.
In summary, the advantages of TPU / TPR rubber band is much higher than rubber rubber band.
