FIELD: polymer materials.
SUBSTANCE: invention relates to novel agriculture-destination materials and, specifically, to polymer compositions for manufacturing film materials based on light-transparent thermoplastic polymers and destined for use as greenhouse coatings. Invention discloses composition including thermoplastic polymer, additive, and stabilizer. Additive contains green silicon carbide α-phase with particle size 0.1-10 μm in amounts between 0.1 and 2.0 %. Thermoplastic polymer is selected from group consisting of polyethylene, polyvinylchloride, polypropylene, polystyrene, polymethylmethacrylate, polycarbonate, polyamide, copolymers thereof, and other suitable thermoplastic polymers.
EFFECT: enabled manufacture of film showing elevated heat-retention properties and providing most favorable temperature conditions in greenhouse.
