Polyurethane foam polyurethane foam introduction, referred to as polyurethane foam, commonly known as styrofoam, polyurethane foam is aerosol technology and technology intersect with the product. It is a will-component polyurethane prepolymer catalyst ﹑ ﹑ foaming agent pressure aerosol cans packed in special polyurethane products. When the material is ejected from aerosol cans, polyurethane foam-like material can rapidly expand and come into contact with air or moisture in the substrate to form a foam curing reaction. OCF after curing adhesive foam with caulk ﹑ ﹑ ﹑ sealed ﹑ acoustic insulation and other effects, is an environmentally friendly energy-saving building materials ﹑ easy to use, can be applied to seal plugging fill joints ﹑ ﹑ fill in the blanks adhesively fixed, noise insulation, especially for plugging and sealing waterproof steel, aluminum doors and windows, doors and walls between the suits. Product Description This product is based on the high expansion of a polyurethane product that can quickly swell ejected from the jar and fill quickly cure a sewing seam with products that can be used in a wet environment. Interfaces for a wide range of applications, crevice, crack sealing, insulating, filling, to insulation, cold resistance, dry, sound insulation and moisture. Like the gap between the separator and the ceiling space, window frames, door frames, walls between the holes, between roof and chimney, wall, ceiling, roof seal around the pipe and the wall of the hole and damage. Adhesive can be used for a variety of materials, such as metal, wood, stone, concrete, and a variety of synthetic materials, such as polyester, polystyrene foam, PVC plastic, rigid polyurethane foams. Specific use 1, install windows and doors: caulk seal windows and doors and the wall between the fixed bonding, bonding facades; 2, the noise muffler: the gap when decorating language lab, studio, etc. to fill, you can play noise muffler effect; 3, routine maintenance: holes, cracks, wall, floor tiles, floor repair, car noise insulation, insulation, filling; 4, waterproof plugging: water pipes, sewer repair vulnerabilities, plugging; 5, packaging and transportation: You can easily wrapped valuable fragile commodity, time-saving shortcuts, seismic pressure; 6, the advertising model: model, sand table production, patch panels; 7, gardening landscaping: flower arranging, gardening made King, light and beautiful. Features 1, good color, white; fine uniform foam. 2, high expansion, to fill the window 3-4; 3, the shrinkage is less than the elastic deformation no better; 4, high closed-cell, high-viscosity, water-resistant insulation; 5, high foam strength, good adhesion, so that the frame and the wall firmly bonded body; 6, foam stability, and ensure good door switch; 7, quick and easy installation, saving labor costs; 8, tubular, two gun-type gun to meet your needs; 9, to pest control, anti- mold and so on.
