Clariant Exolit Flame Retardants
Product Description
The Clariant Exolit series offers high-performance, eco-friendly flame retardants designed to meet stringent fire safety standards across industries. Leveraging phosphorus-based chemistries (ammonium polyphosphate and organic phosphinates), these additives utilize gas-phase and condensed-phase mechanisms to form insulating char layers, suppressing flame spread and reducing toxic emissions.
AP-series variants excel in polyolefins (PP, PE) and intumescent coatings, combining low water solubility (<0.5%) with thermal stability exceeding 275°C to ensure durability in high-temperature processing .
OP-series solutions, tailored for engineering plastics (PA6/66) and polyurethane foams, integrate chemically into polymer matrices, preventing migration while achieving UL 94 V-0 compliance even in thin-walled electronics and automotive components.
