INJECTION MOLDING PROCESSING GUIDE
www.lubrizol.cominjection pressure minimizes the possibility of producing highly stressed parts. This is significant because many new thermoplastic polyurethane molded parts are painted, and paint systems require baking for 30 minutes at 122°C (250°F). Under these conditions, any molded-in stresses would relieve and the result would be a distorted part.
