An understanding of sheet integrity must begin with an understanding of the process, formulation, and raw materials. The hot film is peeled from the calender, cooled and woundup.
Output is controlled by mixing capacity.
Excellent thickness control. Low strain in the membrane. A monograph on vinyl chemistry basic compounding. An article on critical properties of raw materials. The calendering process then produces membrane of homogenous composition, uniform physical dimensions ensuring membrane integrity within the parameters of its design.
