POLYMER COMPOSITION FOR CABLE PLASTIC Russian patent published in 2014 - IPC C08L27/06 

FIELD: chemistry.

SUBSTANCE: polymer composition for cable plastic includes polyvinyl chloride, dioctyl phthalate, diphenylol propane, aerosil, tribasic lead sulphate and a stabiliser. The composition is characterised by use of a complex stabiliser - plasticiser, which is a product containing calcium stearate, magnesium stearate and zinc stearate in molar ratio 2:2:1, with acid number of not greater than 5 mg KOH/g in a medium of chlorinated paraffin wax KHP-30 in weight ratio of 1:6, respectively, and additionally agidol and chalk, with the following ratio of components, pts.wt: polyvinyl chloride 100; dioctyl phthalate 37-47; diphenylol propane 0.1; tribasic lead sulphate 3-5.7; agidol 0.08; chlorinated paraffin wax KHP-30 2-14; chalk 11; aerosil 0.7; said stabiliser-plasticiser 0.33-2.33.

EFFECT: obtaining a more processable polymer composition for cable plastic with improved physical and mechanical properties, high thermal stability, wider range of polymer composition stabilisers.
