INGADA™ PU-112 Rigid Polyurethane Foam – Structural Insulation Grade
Maximum Stability for Heavy-Duty Filling & Industrial Fixing
-
The Pain: Standard foams that shrink, crack, or fail to support the weight of door frames and heavy fixtures over time.
-
The Solution: INGADA PU-112 transforms from a liquid into a “solid-state” structural support. It doesn’t just fill gaps; it reinforces the entire installation with permanent dimensional stability.

Q：Is PU-112 intended for flexible or static applications?
A:PU-112 is a rigid foam designed for static applications where structural support, high load-bearing capacity, and dimensional stability are required.
Q：What is the fire safety rating for PU-112?
A:It has a B2 fire rating according to the DIN 4102 standard.
Q：How much foam volume can I expect from a single 750ml can?
A:A standard 750ml can provides an expansion volume of approximately 40 liters.
Q：Can PU-112 be used for heavy installations?
A:Yes, its high compressive strength makes it ideal for permanently fixing door/window frames, installing bathroom fixtures, and supporting wall panels.
Q:How should deep cavities be filled with PU-112?
A:For deep voids, the foam should be applied in layers (maximum 5cm per layer), allowing each layer to expand and set before applying the next.
