FIELD: polymer materials and composites.
SUBSTANCE: composite granulate, consisting of cylindrical granules 1-2 mm in diameter and 3-4 mm in height possessing residual magnetization 0.4-0.5 mTl, contains: (i) high-pressure polyethylene or polypropylene; (ii) filler dispersed in granulate functioning as modifying additive and being represented by powdered magnetically hard strontium ferrite in concentration 5-25%; and dioctyl phthalate as plasticizing agent with residual magnetization 0.4-0.52 mTl (2%).
EFFECT: improved adsorption properties of filter materials based on fibers made from composite granulate of invention.
