Antioxidant 168 Application scenarios
1. Polyolefins
Polyethylene (PE), Polypropylene (PP) Prevents thermal oxidative degradation during processing such as granulation, injection molding, and extrusion, maintaining melt flow stability.
2. Engineering Plastics
Polycarbonate (PC), Polyester (PET/PBT), Polyamide (PA, Nylon), ABS resin
Improves material stability during high-temperature processing, protecting color and mechanical properties.
3. Other Polymer Materials
Polystyrene (PS), Polyurethane (PU), Elastomers (such as rubber), Adhesives Provides processing stability and prevents oxidative degradation.
Key Usage Point: Synergistic Blending
For antioxidant 168 to achieve optimal results, synergistic use with a primary antioxidant is crucial. This blended system can simultaneously block different chain reaction stages of polymer oxidation, providing long-lasting protection.
Classic Blending Scheme: Typically used in combination with hindered phenolic primary antioxidants (such as antioxidants 1010, 1076, 1790, etc.).

CHLUMIAO® 168 Usage
The antioxidant 168 is a phosphite antioxidant with good compatibility, low volatility, good hydrolysis resistance and high thermal stability. When used in combination with hindered phenol antioxidants and aromatic amine antioxidants, it produces an excellent synergistic effect. The phosphite ester in the composition is used as an auxiliary antioxidant, which does not provide long-term thermal and oxygen stability, and is used in combination with hindered phenol antioxidants to ensure long-term antioxidant efficacy. Suitable for polyester, polyethylene, polypropylene, polyurethane, polyamide, polystyrene, polyvinyl chloride, polycarbonate, adhesives, elastomers. The general dosage is 0.1-0.5%.
Antioxidant 168 is suitable for use in: polyethylene, polypropylene, polystyrene, polyester and polyamide products. It is particularly suitable for polyolefins, styrene mono- and copolymers, elastomers, adhesives, engineering plastics (e.g. PE, PP, PVC, PS, polyamide, polycarbonate, ABS) and other polymers.

Now many areas of product production will be added to the antioxidant 168 to extend the service life of the product, but in the use of many users tend to reflect that the service life of the drug is very short, can not reach the degree of long-term effectiveness, although the effect of the drug can not be effective for a long time, but we can use some methods to extend the effect of the drug, what are the ways to expand the effectiveness of the use of drugs?
1, in the processing of the need to use antioxidant products, in the use of the product can be processed into a processed product before use, can achieve good results in the use of the antioxidant 168 is one of the good choices.
2、Increase in molecular weight in the production process is closely related to the use of the product effect and maintenance time.
3, the extent of the use of antioxidant 168 in line with the product, which requires a more appropriate choice of antioxidant products such as the characteristics of the product, in order to play a good effect.
