FIELD: chemistry.
SUBSTANCE: invention relates to an agent for coating spumescent particles of a styrene polymerisate, as well as spumescent particles of a styrene polymerisate having at least one coating. The agent contains tristearyl ester with melting point of 60-65°C and triglyceride of a hydroxy-substituted fatty acid with 16-18 carbon atoms and melting point of 70-95°C.
EFFECT: after application on spumescent polystyrene particles and subsequent pre-foaming, the composition of the agent provides low susceptibility to sticking of the particles and enables fast processing of pre-foamed particles with low electrostatic charging to obtain moulded articles from foam plastic with good mechanical properties.
