FIELD: electrical engineering.
SUBSTANCE: invention relates to the system of stabilisers including a thermal stabiliser selected from organic and inorganic lead compounds and a substrate composed by partially calcined dolomite of formula Mt1X1*CaX2. Note here that Mt1 stands for magnesium, X1 stands for oxygen and X2 stands for oxygen. Calcined dolomite is processed by the application of metal perchlorate of formula Mt2(ClO4)m*nH2O, wherein Mt2 stands for sodium, m stands for 1, n stands for the number of 0 to 3. The system of stabilisers does not contain any of the compounds selected from the group including B and C. Note here that B stands for at least one nitrogen-bearing organic compound selected from the group including B1 and B2. Note here that B1 stands for tret-alkanolamine while B2 stands for enaminone or carbamide. Note also that C stands for alumohydroxocarbonate of the alkaline metal of formula (C) (M1-xZnx)yAl2(OH)4+2yCO3*zH2O (C) wherein M stands for magnesium and/or calcium; x stands for the number of 0 to 0.5, y stands for the number of 2 to 8 and z stands for the number of 0 to 12. This invention discloses also the system of composition stabilisers and articles, their application and making of the dolomite substrate.
EFFECT: sufficient long-term polymer stabilisation, higher resistance to light and temperature effects.
