Therefore, the aging of rubber bands is generally solved from the above aspects. 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 elastic rebound rate, which 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, it redesigns the formula from the following aspects:
.Select rubber with large molecular chain flexibility: natural rubber (Vietnam's high-quality natural rubber raw material)
/> .In 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
.Chenyu rubber does not use a large amount of fillers, so the rubber content is controlled above %. The amount of reinforcing agent is also very small to maximize the retention of the high elasticity of the rubber.
.In addition, in terms of selecting softening accelerators, it is rare to use highly aromatic and high-viscosity operating oils that can reduce elasticity. Adding a certain amount of ester plasticizer can enhance the resilience of the rubber ring.
In summary, 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 to other domestic rubber band manufacturers, so you can choose it with confidence.
