Product Description

Products Introduction

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:

1good flowability, by regulating formula to suit different pipe diameters.

2good temperature-resistance property, long standing in 150

3good low temperature dimensional stability.
