Thermal Stability of Flame Retardants in High-Temperature Processing
Calcium Bromide (CaBr2) Completion and Packer Fluids: A Technical Overview
Insulation foam needs
EPS and XPS building insulation must meet fire standards without compromising thermal performance. Historically HBCD was used, but it has been phased out under the Stockholm Convention.
Modern options
Polymeric brominated flame retardants, often styrene-butadiene based, now replace HBCD in EPS and XPS. They provide the required flame retardancy at low loading and are not persistent in the way HBCD was.
Selecting a supplier
Confirm the flame retardant is approved for building insulation in your market and request fire-test data for the finished foam.
Frequently Asked Questions
What replaced HBCD in foam insulation?
Polymeric brominated flame retardants, typically styrene-butadiene based, have replaced HBCD in EPS and XPS insulation.
Do flame retardants affect foam insulation value?
At the low loadings used in polymeric brominated systems, thermal insulation performance is largely preserved.
