The ability of a polymer to withstand environmental degradation, particularly from ultraviolet (UV) light, is crucial for its performance and lifespan. NINGBO INNO PHARMCHEM CO.,LTD. offers HALS 783, a high-performance Hindered Amine Light Stabilizer (HALS) blend renowned for its versatility and effectiveness across a broad spectrum of polymers. This article explores the diverse applications where HALS 783 provides indispensable protection.

HALS 783 is a synergistic blend of UV-944 and UV-622, high molecular weight HALS that deliver exceptional light stability and long-term thermal stability. Its key properties – low volatility, resistance to extraction, and good compatibility with most polymers – make it an ideal choice for enhancing the durability of materials exposed to UV radiation and heat.

The most prominent applications for HALS 783 are within the realm of polyolefins. This includes polypropylene (PP) and various types of polyethylene (PE), such as LDPE, LLDPE, and HDPE. HALS 783 is particularly effective in protecting PP fibers and films, as well as PE films, tapes, and thick sections. These materials often face intense sunlight, and HALS 783 ensures they maintain their physical properties and appearance over time, preventing premature failure due to photodegradation.

Beyond polyolefins, HALS 783 also finds critical applications in other polymer systems. It significantly improves the light stability of polyurethane (PU) materials, which are used in applications ranging from coatings and adhesives to foams and elastomers. For polyamides (nylons), HALS 783 provides essential UV protection, safeguarding products like automotive components and textiles from degradation caused by sunlight exposure.

Furthermore, HALS 783 is highly effective in stabilizing polyesters, ensuring that polyester resins and products maintain their integrity and performance characteristics when exposed to environmental stresses. Its applicability extends to engineering plastics, such as ABS, and it is a preferred choice for thick sections where UV penetration and thermal management are critical. The compatibility of HALS 783 with these diverse polymer types, coupled with its ability to meet indirect food contact approval requirements, makes it an incredibly versatile and valuable additive for manufacturers across numerous industries.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing advanced stabilization solutions like HALS 783, enabling industries to produce more resilient and longer-lasting products through effective UV protection across a wide range of applications.
