Name: Clariant Exolit AP 422 Flame Retardant
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Clariant Exolit AP 422 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-temperature engineering thermoplastics.
Low water solubility and superior hydrolytic stability, ensuring long-term performance in humid environments and during processing.
Halogen-free and compliant with major environmental regulations including RoHS and REACH.
Good dispersion characteristics in polymer matrices, supporting uniform flame-retardant performance without compromising mechanical properties.

Typical Applications Of Clariant Exolit AP 422 Flame Retardant

Polypropylene (PP) for automotive interior components requiring UL 94 V-0 rating.
Thermoplastic elastomers (TPEs) used in cable jacketing and flexible industrial hoses.
Engineering plastics such as polyamide 6 (PA6) and polybutylene terephthalate (PBT) for electrical connectors and housings.
Wood-plastic composites (WPCs) for outdoor decking and cladding where fire safety and weather resistance are critical.
Intumescent coatings and sealants for passive fire protection in construction applications.
