Bisphenol S usage

Bisphenol S is used in the Epoxy Resin coating of food and beverage cans to protect food from direct contact with metal, prevent corrosion of metal cans and aluminum boxes by food raw materials, and is often used in the packaging of milk powder, meat products and surimi products. Bisphenol S role basically has two, one is because of the epoxy coating can easily residual hydrochloric acid in the process of polymerization, neutralization using bisphenol S, it is because of the direct contact with food is more acidic, grease and bisphenol S alternative epoxy coating in preference to the moisture in food, such as acid reaction, thus improving the stability of the coating, Also avoid metal materials and food contact and corrosion. Bisphenol S is a chromogenic agent in thermal paper. The European Commission claims that 30% of thermal paper enters the recycling stream. Many paper products, such as kitchen paper, food cartons (pizza cartons, noodles cups, popcorn cartons, etc.) are made from recycled paper. Therefore, the Chemicalbook cycle of thermal paper allows BPS to enter the paper recycling system and contaminate food contact paper products. Bisphenol S is one of the synthetic monomers of polyether sulfone, which is a kind of amorphous thermoplastic resin. Because of its polymer material structure, it has toughness, transparency and very high heat resistance (continuous use temperature up to 180 degrees, instantaneous high temperature up to 220 degrees). , light weight, has good mechanical properties, impact fracture resistance, high chemical resistance, excellent hydrolysis stability, good microwave transmittance, so it is used in high temperature heating and repeated high temperature heating food utensils increasingly widely used. For example, baby bottles, airline dinner plates, microwave cooking utensils, non-stick pan coating.
