Product Description
rigid polyol prix and isocyanate polyurethane spray foam is spray blend polyols, it reacts with isocyanate to produce foam which has excellent performances, which are as follows,
1) fine and uniformity cells
2) low thermal conductivity
3) perfect flame resistance
4) good low temperature dimentional stability.
It applies to all kinds of thermal insulation engineering which uses the spray technology, such as cold rooms, pots, large-scale pipelines and construction metope etc.

Another PU--- Wood Imitation Rigid Polyurethane Blend Polyols
hardness, simple molding process, high production efficiency and excellent appearance. Characteristics are as follows, 1.Excellent
repetition molding property. It not only can mould certain shape size, but also mould lifelike wood texture and other designs,
good touch. 2.Appearance and feel close to wood, which could be planed, nailed, drilled, and carved patterns or designs. 3.Mold
can be aluminum or steel, and silicon rubber, epoxy resin or other resins, which are low cost and easy machining. 4.Process is
simple, fast, high efficiency of qualified. 5.Physical and mechanical properties is one of optimal synthesis wood produced by
various polymer. Physical property can be controlled by adjusting the formula.
