The best materials available in the world and the cold insulation industry in various industries are polyurethane, which has a very low heat transfer coefficient and allows heat and cold storage of +1 to -1. Polyurethane is caused by the reaction of hydroxyl (polyol), isocyanate, permitted gases, permitted additives in firefighting materials.
Polyurethane is mainly used in the oil, gas, petrochemical, pharmaceutical and food industries for insulation of pipes and tanks as well as in the construction industry, in the production of wall panels and metal roofs to prevent heat.
