The main raw materials of colored rubber bands include rubber, latex and industrial pigments. Rubber and latex are non-toxic raw materials, but in order to achieve bright colors, colored rubber bands usually use industrial pigments, which are less safe and may contain ingredients that are harmful to the human body, such as heavy metals such as lead and cadmium. In addition, in order to adjust the properties of rubber bands, plasticizers may be added, which interfere with human hormones.
Characteristics of rubber bands of different materials
Rubber: Natural rubber (NR) has good tensile resilience and low compression deformation rate, and is often used in occasions that require high rebound effects.
Latex: Latex rubber bands have stronger tensile strength and better softness, but have a pungent smell, low environmental safety, and poor high temperature resistance.
Silicone: Silicone rubber bands are safer and more environmentally friendly materials with good high temperature resistance and stability. They are widely used in occasions where they come into contact with the skin for a long time.
