Over the years they have also been used to make colored rubber bands.
The rubber band specifications are as follows:

The mechanical properties of rubber bands are: tensile strength;
19.6MPa elongation at break;700%, tear off permanent deformation;
15%, aging coefficient (70℃;72H);0.8
 
In terms of material selection and formula, the rubber used in transparent and natural rubber bands is generally selected as a first grade natural rubber (3L pure natural Vietnam imports) using sulfur as vulcans, promoters commonly used accelerators DM, TMTD, etc., basically no filler.
The rubber content is very high, generally more than 93%.
The formula is as follows: natural gelatin 100 parts, sulfur 2 parts, accelerator 0.8 parts, antioxidant 1.0 parts, stearic acid 0.5 parts, zinc oxide 1.5 parts, light active calcium carbonate 1.0 parts, Vaseline 0.5 parts, gum content 93.1%.
