High-density polyurethane is obtained after mixing raw materials and letting them react. Hardness, colour and covering follow the customer; any colour can be produced. The material is molded into insoles, medical parts, motorcycle protective equipment, mousepads and wristbands. There is no irritating odor. It can be combined with TPU and gel. Raw materials are loaded into separate tanks, pumped to the mixer and cast into the mold; after molding at a set time and temperature the part is demolded. Free density and reaction time are checked before production; hardness and durability are tested on the finished part.
