POLYVINYLCHLORIDE COMPOSITION Russian patent published in 2005 - IPC

Abstract RU 2264419 C1

FIELD: polymer materials.

SUBSTANCE: invention relates to rigid polyvinylchloride compositions including plasticizing and coloring fillers for manufacturing mainly building materials, which composition may be, in particular, used for manufacturing molded profiled articles. Multifunctional filler is constituted by bitumen-containing rock with 1-8% bitumen and used in amount of 1 to 20 wt parts per 100 wt arts polyvinylchloride.

EFFECT: reduced expenses, enhanced flowability of melt, imparted coloring effect without additional use of pigments, and extended application are for local raw material resources.
