Rigid polyurethane foam in industry

Polyurethane foam is the most important part in all kinds of polyurethane products, the main feature of it is porous, and thus it is relative low density and high specific strength. It can be made into soft, semi-rigid and rigid polyurethane foam according to the raw material and formula changes; it can be divided into polyester polyols, polyether and Castor oil polyurethane foam according to the variety classification; it classified into blocks, molding and spray polyurethane foam types according to their method of foam.

Rigid polyurethane foam are generally foam at room temperature, the forming process is relatively simple. Classified according to the degree of mechanization of construction, it has hand-blowing and foaming machine; classified according to the foam pressure, it has high pressure foaming and low pressure foam; according to molding it can be divided into pouring of foaming and spraying foam.

Rigid polyurethane foam is polymeric organic material prepared by polymerization of polyether and isocyanate. Waterproof and thermal insulation properties of rigid polyurethane foam materials used in industrial refrigeration, insulation, solar energy and water areas. With the development of the times, rigid polyurethane foam materials is the construction insulation and waterproofing material trends. Therefore, it is necessary for rigid polyurethane foam materials used in construction to take attaches great importance to the attitude. Polyurethane foam is the best energy-saving insulation materials at present, the performance is better than the XPS, EPS thermal insulation system.

In China construction projects, rigid polyurethane foam are widely used in insulation and waterproof roofing, and cold storage, greenhouses, grain thermal insulation. Roof, cold storage, all of which develop technical specification for the corresponding construction. As the energy- save requirements increases and technical development of rigid polyurethane foam insulation, building insulation industries pay more attention to rigid polyurethane foam.

Polyurethane foams are the most important polyurethane products, it has versatility and excellent performance, soft PUR foams and semi-rigid PUR foams are mainly used for furniture padding and decorative materials, carpet backing materials, car mats, clothes lining sports pad material, building sound-absorbing materials, packaging materials as well as mattresses and instrument, and so on. Moulding of flexible polyurethane foam mainly used for car seat pad material and motorcycle, bicycle seat, while rigid polyurethane foams are mainly used for refrigerators, cold storage industry as insulation material, accounting for 57.5% of the total consumption of rigid cellular plastics.

As technology advances and the development of construction industry, polyurethane rigid foam material costs can be effectively reduced, and the application of rigid polyurethane foam materials in construction work will the popularization and promotion. Click here now!
