■What is polyurethane rubber? Depending on how it is bonded, it can be classified into polyester (EU) and polyether (AU). The ester type is prone to hydrolysis (due to steam, heat, acid, etc.) but has excellent oil resistance. The ether type is less prone to hydrolysis but has inferior oil resistance. Typically, polyurethane (PU) is a thermosetting resin that hardens when heat is applied, so it requires a different method of mold usage compared to general thermoplastic resins. In this case, a method called casting molding is used, where pre-melted polyurethane (PU) is poured into the mold and heated to cure. There are also materials compliant with the Food Sanitation Act, so please make use of them. *For more details, please refer to the PDF materials or feel free to contact us.
