Silicones, whatever their formulations or applications, are completely BPA-free. This chemical substance, which stands for Bisphenol A, has been used since the 1950s to reinforce certain polycarbonate plastics and epoxy resins, particularly those used in food and beverage containers. Research has shown that it may affect human health, especially hormone levels and other vital processes such as reproduction, fetal development and growth. Many countries around the world have therefore strictly regulated or banned the use of BPA in food contact products. However, BPA is never used in silicone products of any sort and is therefore not a health hazard, either for people manufacturing silicone products or end-users.
