Rubber bands generally have strong resilience. Rubber, the material they are made of, is a viscoelastic material characterized by high elasticity and viscosity. We typically refer to rubber's resilience simply as elasticity, and rebound rate as a measure of its viscous resistance. The greater the mobility of the cross-linked network of vulcanized rubber, the higher its resilience. In rubber production, the manufacture and design of high-elasticity rubber bands generally focus on the following aspects:
01
Select rubber with highly flexible molecular chains, such as natural rubber.
02
During the vulcanization process, use vulcanized rubber with a moderately high cross-link density, appropriately increasing the effect of sulfur. However, rubber band manufacturers should avoid using over-accelerators.
03
Avoid using large amounts of fillers in the rubber, keeping the rubber content above 85% and using minimal reinforcing agents to maximize the rubber's high elasticity.
04
Furthermore, when selecting softening accelerators, avoid using highly aromatic and high-viscosity operating oils, which can reduce elasticity. Adding a certain amount of ester plasticizer can enhance the rubber band's resilience.
High-quality rubber bands offer a long service life, excellent resilience, and resistance to deformation and breakage. They are also resistant to aging, corrosion, and high and low temperatures. With the rapid development of automated strapping technology, the application of rubber bands as a strapping material is gradually expanding towards automation.
