From a perspective, rubber is a viscoelastic material, that is, it has high elasticity and viscosity at the same time. Usually, we refer to the resilience of rubber as elasticity, and the rebound rate is an indicator of the visco-resistance properties of rubber. The greater the mobility of the cross-linked structure of vulcanized rubber, the higher its resilience. Therefore, when Chenyu Rubber manufactures high-elastic rubber bands during the production process, the formula is redesigned from the following aspects: .Select rubber with large molecular chain flexibility: natural rubber (Vietnam’s high-quality 3 natural rubber raw materials)
.During the vulcanization process, we use vulcanized rubber with a cross-linking density that is not too large to increase the effect of sulfur appropriately, but we avoid using super-speed accelerators
3. Chenyu rubber does not use a large amount of fillers, which is the content of the rubber. In the above, the amount of reinforcing agent used is also very small, so as to retain the high elasticity of rubber to the greatest extent.
.In addition, in terms of selecting softening accelerators, the use of highly aromatic and high-viscosity operating oils that can reduce elasticity is rarely used. Adding a certain amount of ester plasticizer can enhance the resilience of the rubber ring.
To sum up, although the elasticity of the rubber bands produced by Dongguan Chenyu Rubber is not as good as that of imported rubber bands, it is still outstanding compared with other domestic rubber band manufacturers, so you can choose it with confidence. .
