This product is a type of blend polyols, which is specially researched for rigid PUF to produce thermal insulation pipes. It is widely used in steam pipes, liquefied nature gas running pipes and other fields. The characteristics are as follows:
· Excellent flowability, by regulating formula to suit different pipe diameters.
· High temperature-resistance property, long standing in 150°C
· Superior low temperature dimensional stability.
