ASTM C591 – 17

This standard does not encompass all polyurethane modified materials. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

In case of dissatisfaction with the results of the tests, the producer or supplier may request a rehearing. Physical property requirements vary by application and temperature.

Subscription pricing is determined by: Polyurethane modified polyisocyanurate and other polyurethane materials are similar, but the materials will perform differently under some service conditions. The thermal insulation is produced by the polymerization of polymeric polyisocyanates in the presence of polyhydroxyl compounds, catalysts, cell stabilizers, and blowing agents. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
