Weather Resistant Polyether Polyol Outdoor Pipeline Spraying Insulation Foam

Weather Resistant Polyether Polyol Outdoor Pipeline Spraying Insulation Foam. Forms high closed-cell foam after foaming, effectively block heat and cold transfer, greatly reduce pipeline energy loss for heating, refrigeration and chemical pipelines. Dense cell structure prevents water vapor penetration, good hydrolysis resistance, suitable for buried, underground and high-humidity outdoor pipeline projects without insulation failure. Good fluidity at normal temperature, evenly mixed with MDI, easy to wrap irregular curved pipes, no sagging during vertical pipeline spraying, improve on-site construction efficiency. Firmly bond with steel, plastic, stainless steel and composite pipes, fit pipe surface tightly without hollowing, delamination or cracking. Compatible with low-GWP eco blowing agents; can be matched with flame retardants to reach B1/B2 fire grade, long service life under alternating hot and cold conditions.
