Non-Classified PIN FR for intumescents
Clariant (pinfa member) low-solubility nitrogen phosphorus non-halogenated FR for environment and fire safety. The ammonium polyphosphate based compound is non-Classified (for health and environment as used), does not use melamine or other classified precursors so is SVHC-free and is (bio)degradable to natural phosphate and ammonium moieties. The PIN FR is supplied in aqueous suspension and is non-hygroscopic. It can be used in cellulose materials (wood, paper), composites and polymers, including in polyurethane foams, in epoxies and in thermosets. It is also highly effective in firestops, sealings and intumescent coatings to protect materials from burning and from heat in case of fire.
