Name: Clariant Exolit AP 420 Flame Retardant
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Clariant Exolit AP 420 Flame Retardant

High-efficiency intumescent flame retardant based on ammonium polyphosphate (APP) with optimized particle size distribution.
Excellent thermal stability up to 300 °C, enabling compatibility with high-melt-processing polymers.
Low water solubility and hydrolysis resistance ensure long-term performance in humid environments and during processing.
Halogen-free formulation supports compliance with RoHS, REACH, and UL 94 V-0 requirements for many polymer systems.
Good dispersion characteristics in polyolefins, thermoplastic elastomers, and engineering plastics without significant viscosity increase.

Typical Applications Of Clariant Exolit AP 420 Flame Retardant

Flame-retarded polypropylene (PP) for automotive interior components (e.g., dashboards, pillar trims).
Wire and cable jacketing compounds based on ethylene-propylene rubber (EPR) and thermoplastic vulcanizates (TPV).
Electrical enclosures and housings made from polyamide 6 (PA6) and polyamide 66 (PA66).
Intumescent coatings and sealants for passive fire protection in construction applications.
Flexible and rigid foams used in furniture and bedding requiring low-smoke, halogen-free fire performance.
