CONDUCTING ELECTROCONDUCTIVE FOAM PLASTICS FROM PARTICLES BASED ON THERMOPLASTIC ELASTOMERS Russian patent published in 2019 - IPC C08J9/224 C08J9/232 

FIELD: chemistry.

SUBSTANCE: invention relates to foam plastic particles based on a thermoplastic elastomer which is a polyurethane having a coating which consists of an electrically conductive substance which is graphite. Described is a method of producing foam plastic particles by applying a coating on said particles of foam plastic using an emulsion of an electroconductive substance in a plasticiser, as well as a method of producing foam plastic from particles as a result of thermal bonding of said particles of foam plastic using high-frequency electromagnetic radiation. Described also are foams with specific electrical resistance of less than 10⁶ [Ω mm²/m] and method of using foam plastic from particles for packaging or shoes.

EFFECT: technical result is providing elastic and at the same time light materials with thermal and electrical conductivity of foamed plastic, which vary as a result of expansion or compression.
