Release agent is a functional substance that acts as an intermediary between the mould and the finished product and is widely used in a variety of moulding operations such as metal die casting, polyurethane foams and elastomers, glass fiber reinforced plastics, injection moulded thermoplastics, vacuum foamed sheets and extruded profiles. Mould release agents are chemically, heat and stress resistant, do not readily disintegrate or wear away, bond to the mould without transferring to the finished part, and do not interfere with painting or other secondary processing operations.
