Why can rubber bands shrink back after being stretched?
Rubber bands can shrink back after being stretched, which is caused by the rubber molecules in them. Rubber molecules are small things that love to move very much. They are arranged hand in hand. Because each molecule is moving, their team is always crooked and not neat.
If we pull the rubber band hard, the rubber molecules will lose the "freedom" to move arbitrarily, and the arranged team will become neat. From the appearance, it looks like the rubber band is stretched and straightened. But these rubber molecules are unwilling to be restricted. They strongly demand to restore the "freedom" of movement, so a force to restore the original state will be generated. This is the elasticity of rubber, and it is also the reason why the rubber band can shrink back after being stretched.
The scientific name of the rubber band is latex rubber ring and latex tape. It is made of latex by dipping. It has the characteristics of large elongation, good resilience, low price and easy use. Its manufacturing process includes dipping, vulcanization, demoulding, cutting rings (strips) and other processes. It is mainly used for bundling items.
Daoak has been deeply engaged in the research of polymer materials for nearly 20 years. It has a number of patented technologies and self-developed formulas. The raw materials used in its production are natural rubber produced south of 15° north latitude, which ensures that the rubber bands produced have a long service life, good resilience, and are not easy to deform or break. They have the advantages of anti-aging, anti-corrosion, high temperature resistance, and low temperature resistance.
The company's products have passed the ROHS index certification of SGS, do not contain various types of heavy metals and toxic substances that are prohibited by regulations, and are environmentally friendly and non-toxic. If you are looking for a reliable supplier, Daoak is the best choice.
