Plastic forming process with a polymer mixture is rolled between rotating calender to create a plastic film. Beskrivning The process A polymer mixture [1] is heated and fed between two rotating main calenders [2]. The pulp is pressed to a rough thickness [3] and is then rolled by subsequent rollers to the desired thickness. Calendering Process films Advantages and disadvantages In comparison with alternative methods Best quality plastic sheets Adapted for heat-sensitive polymers Good opportunity to mix with solid additives Cost Saving Opportunities for raw materials Holes or voids may occur for workpieces thinner than 0.15mm Risk of air pockets
