POLYMERIC COMPOSITION HAVING LOWER COMBUSTIBILITY Russian patent published in 1995 - IPC

Abstract RU 2039771 C1

FIELD: manufacture of electrical engineering parts. SUBSTANCE: the polymeric composition comprises polypropylene, hexabromocyclododecane, antimony trioxide, a phenol thermostabilizer and a chemical polymethylenecarbamide additive, the ratio of the components being as follows (wt):6.0-16.0 hexabromocyclododecane; 3.0-8.0 antimony trioxide; 0.2-15 phenol thermostabilizer; 4.0-14.0 polymethylenecarbamide; and polypropylene, the balance. The use of polypropylene composition having the above components makes it possible to manufacture various parts having combustion resistance of class ПВ-0 and a thermooxidative ageing resistance of more than 170 and not greater than 540 hours. EFFECT: improved properties of the polymeric composition. 2 tbl
