Polyurethane is a polymer composed of organic units joined by urethane. Polyurethane formulations cover an extremely wide range of stiffness,hardness,and densities. A component moisture care, polyurethane foam for general purpose applications in mounting,filling,sealing insulation and soundproofing in concrete,plaster,brick,floorboard,most plastics,metal,glass,or wood. It gives good expansion yield and no sagging. It is ozone friendly propellant. It provides good thermal and acoustic insulation. It is mouldproof,water and ageing resistant. Ideal for mounting windows and doorframes. Heat insulation and sewerage and central heating,fixing,and insulating of wall pannels,roof tiles etc.Fills irregular holes or awkward gaps and other domestic, industrial and automotive applications.
