EFFECT OF TALC ON THE PROPERTIES OF A COMPOUND BASED ON ETHYLENE-PROPYLENE COPOLYMER

The aim of the research is to study the possibility of replacing Korean-made talc with inexpensive talc from an Afghan deposit, processed in Uzbekistan and used for the production of polypropylene compounds. In the future, these compounds are used for the manufacture of plastic car parts. A block copolymer produced by Uz Kor Gaz Chemical was chosen as a binder. For this, the influence of the content and type of talc on the properties of a compound based on an ethylene-propylene copolymer was studied. The properties of the obtained compounds checked using ISO standards. The fractional composition of the studied types of talc, strength, thermophysical, gravimetric properties of compounds with different concentrations of talc were studied. The results of studies of these properties of compounds based on ethylene-polypropylene copolymers modified with various types of talc filler revealed the possibility of obtaining materials with specified properties based on Afghan talc
