In some cases, the uncured or partially cured polymers or materials can be molded into their final shape, or used as adhesives. Once hardened, a thermoset polymer or material cannot be re-melted in order to be reshaped. WebbThe processing differences between thermosets and thermoplastics are significant, and thermoset materials cannot be reshaped or reformed once they have “set”. Thermosets resist higher levels of heat, however, and thermosets provide stronger corrosion resistance than thermoplastics. jojo bizarre adventure wallpaper live
