How to buy rubber bands, what kind of rubber bands are more durable and good elasticity

Rubber bands in general life depends on the situation, talcum powder can prevent it from aging, rubber bands if you do not use to put there generally half a year of useless or melting. So most of them are temperature related. More professional practice is to save at low temperatures, in a large number of rubber warp inside the talcum powder to prevent sticking.

1. Aging resistance assortment should be silicone rubber bands. The main material of rubber bands is rubber, which is an organic substance, whether natural rubber or synthetic rubber, are polymer polymers, whose molecules are made of many of the same, simple structural units through **** valence bond repeat connection.

2. The molecular chain of rubber is very long and helically curved, when stretched by external forces, these helically curved molecules will straighten and stretch; when the external forces are withdrawn, due to the influence of the internal forces, they will be restored to a helically curved shape, so that the rubber shows a strong elasticity.

3. Depending on the material of the rubber band, the price, function and use will be different
