Description

Poly[N,N'-Bis(2,2,6,6-Tetramethyl-4-Piperidinyl)-1,6-Hexanediamine-Co-2,4-Dichloro-6-Morpholino-1,3,5-Triazine] is a high-performance polymeric hindered amine light stabilizer (HALS) designed for long-term protection of polymers against photo-oxidative degradation. This compound matters because it provides exceptional durability and weatherability, significantly extending the service life of plastics exposed to harsh environmental conditions. It is a critical additive needed by manufacturers in the automotive, construction, agriculture, and packaging industries for producing high-quality, UV-resistant polymers like polyolefins, engineering plastics, and coatings.

Application

• Automotive Components: Protects exterior plastic parts (bumpers, trim, under-hood components) from UV-induced fading, chalking, and loss of mechanical properties.
• Construction and Building Materials: Essential for stabilizing greenhouse films, geomembranes, siding, roofing membranes, and pipes against sunlight and weathering.
• Agricultural Films: Extends the functional lifespan of mulch films and crop protection coverings by preventing polymer breakdown from prolonged sun exposure.
• Industrial and Consumer Packaging: Used in films, containers, and fibers to maintain clarity, color, and strength during storage and use.
• Engineering Plastics and Fibers: Stabilizes polypropylene (PP), polyethylene (PE), and other polymers in demanding applications requiring long-term thermal and light stability.
• Protective Coatings and Paints: Incorporated into industrial and automotive coatings to prevent gloss loss, cracking, and delamination caused by UV radiation.
