VI-P01 blend polyols is the pale yellow to brown yellow transparent liquid, which is specially researched for rigid PUF to produce thermal insulation pipes with water blowing agent. Widely used in steam pipes, liquefied nature gas running pipes, oil pipes and so on. It have the advantage of the flow ability by regulating formula to suit different pipe diameters, the high temperature-resistance performance, the long standing in 150℃ and the excellent low temperature dimensional stability.
