METHODS FOR PRODUCING CONTINUOUS SLABSTOCK FLEXIBLE POLYURETHANE FOAM INCLUDING MAGNETITE PARTICLES AS A STRESS AND PAIN REDUCING MATERIAL

摘要

The invention relates to polyurethane composite material that reduce waist and back pain occurring in the human body and remove stress on the human body. The invention is a composite material obtained by addition of magnetite particles (1) into the slabstock flexible polyurethane foam (2) during the production or coating application of the magnetite particles (1) onto the upper part of the continuous slabstock flexible polyurethane foam (2) after the production.
