With plastics, heated rollers squeeze films or sheets to produce materials that have a glossy finish. The calendering process begins by heating and mixing resins, pigments, stabilizers and plasticizers in an industrial mixer. This hot mix is then passed through a two-roll mill to form the sheet.

Any plasticizer should be added last. Hot melts can be mixed in high-powered Sigma blade mixers capable of being heated. The usual order of addition is polymer followed by the gradual addition of alternating increments of filler and plasticizers. Very stiff compounds may be mixed in a Banbury or on a two-roll rubber mill. NOTE
