NCFI Polyurethanes, a manufacturer of
foam products including spray foam insulation, and
Lubrizol,
supplier of CPVC resins for the manufacture of plumbing pipe and fire sprinkler
systems, have created a
Suggested Application Test Protocol Guideline.
This is in response to a recent accusation concerning the safety of spray foam
and Environmental Stress Cracking (ESC).
The
Spray Polyurethane Foam Alliance (SPFA) issued a
report proving SPF is chemically compatible with CPVC and is not a source of
ESC. Upon further rigorous testing of their own, NCFI and
Lubrizol came up with similar findings. When applied properly according to standard application
guidelines, spray foam is safe and effective to use with CPVC plumbing pipes
and fire sprinkler systems.
The new Guideline is being shared with other spray foam
manufacturers to correct misinformation throughout the industry.
