Abstract RU 2111989 C1

FIELD: manufacturing of film materials on the base of polyvinyl chloride (PVC). SUBSTANCE: polymer composition comprises, wt.p.: polyvinyl chloride, 100, peptizing agent, 46-50; calcium stearate, 1.5-2.5; lead silicate, 3-5; stearine, 0.4-0.6; chrome yellow, 0.02-0.04; titanium dioxide, 3-5; technical carbon, 0.005-0.02; chalk, 12-22; modified serpentine, 5-15. Mass ratio of serpentine and chalk is 1:(0.8-4.4), respectively. Lengthwise tensile strength of PVC film is 12.3-12.9 MPa and its across tensile strength being 10-10.2 MPa. EFFECT: improved quality of desired product. 1 tbl
