摘要

Process for the manufacture of thermal acoustic insulation for automobilu00ecstica industry and civil construction ".Consisting of five possible formulas composed with stearic acid (stearin), paraffin oil, carbon black, coal (antracitoso), calcium carbonate (calcite), cellulose fibres.Ethylene vinyl acetate (EVA), patchwork septum EVA, polyethylene bag and burrs of EVA, barium sulphate,Master of ethylene vinyl acetate (EVA) + ethylene propylene diene monomer and pigment colored (EPDM)The development aims to obtain a thermal acoustic insulation that has greater efficiency with increased elongation and tensile and has low flammability.
