What elements make up rubber bands?

Rubber bands are primarily made from natural rubber, which is derived from the latex of rubber trees, or synthetic rubber, such as styrene-butadiene rubber (SBR) or ethylene-propylene-diene monomer (EPDM). The main elements that compose these materials include carbon, hydrogen, and small amounts of sulfur, which is used in the vulcanization process to enhance elasticity and strength. Additives like fillers, colorants, and stabilizers may also be included to improve performance and durability.
