Because of the unique nature of COHRlastic foam, SGPPL CHR has undertaken a rigorous testing program which is performed at outside independent laboratories.
The tests document the flame resistant properties and low levels of toxicity and smoke generation as well as mechanical and electrical properties. Details are on file at SGPPL CHR.
Tests, claims, representations and descriptions regarding flamability are based on standard laboratory tests and, as such, may not be reliable for determining, evaluating, predicting or describing the flammability or burning characteristics under actual fire conditions, whether used alone or in combination with other products. Accordingly, each potential user should make an individual determination whether the flammability or burning characteristics of the product are suitable for the purpose intended by the user.
CHR provides certification to the specifications listed when requested with order. All properties are typical values and should not be used for writing specifications. Please consult plant concerning updated specifications. Government and military specifications are being revised at the time of this catalog printing.
