CAS:26544-27-4

Application Instructions

An environmentally friendly and phenol-free pentaerythritol diphosphite ester antioxidant with a high content of available phosphorus, which can be used as an environmentally friendly stabilizer for PVC and can improve the transparency and temperature resistance of PVC products. It contains no free phenols and no phenolic products are generated during hydrolysis or degradation. It is a completely phenolic phosphite antioxidant. When added to high molecular materials such as (unsaturated) resins, polyether alcohol-free resins, and epoxy resins, it can protect the color of the polymer during the processing and synthesis process and improve the thermal stability of the polymer in the later stage. Suggested addition amount: 0.1-2.0%

Antioxidant 8608 Application scenarios

1. Polyolefin Processing and Products:

Used in the production of films, fibers, injection molded parts, pipes, and profiles of polypropylene (PP) and polyethylene (PE, including LDPE, LLDPE, and HDPE). Adding approximately 0.2% to film masterbatches can significantly improve tensile strength retention and inhibit yellowing and embrittlement; in HDPE pressure pipes and PP profiles, it prevents thermal degradation and long-term aging cracking, maintaining structural integrity and dimensional stability.

2. Engineering Plastics Manufacturing:

Compatible with polycarbonate (PC), polyamide (PA), polybutylene terephthalate (PBT), acrylonitrile-butadiene-styrene copolymer (ABS), etc. Used in electronic and electrical components, automotive gears, connectors, etc., it can prevent thermal degradation during high-temperature processing, improve material thermal stability and long-term durability, and, when combined with UV absorbers, can enhance outdoor weather resistance.

3. PVC Environmentally Friendly Stabilizing System:

As an environmentally friendly auxiliary heat stabilizer for rigid PVC (such as door and window profiles, building components), it inhibits thermal degradation during extrusion, improves initial color and long-term weather resistance, prevents discoloration and degradation of UV resistance, and leaves no free phenol residue, meeting environmental protection requirements.

4. Polyurethane and Polyester Materials:

Applied in the synthesis and processing of polyurethane products, unsaturated resins, and polyester polyols, it protects the color and transparency of materials under synthesis and subsequent high-temperature conditions, improves later-stage thermal stability, and reduces performance degradation caused by oxidation.

5. Coatings and Adhesives:

Used in high-temperature curing coatings and adhesive systems, it prevents coating/adhesive layers from oxidizing, yellowing, losing gloss, and degrading in performance during curing and long-term use, especially suitable for coating formulations requiring high gloss and transparency.

6. Lubricating Oils and Related Fields:

As an antioxidant and anti-wear additive for lubricating oils, it can decompose hydroperoxides and chelate metal ions, delaying the thermal and oxidative aging of oils, improving thermal stability and service life, and is suitable for industrial lubricating oils operating under high temperature and high load conditions.

7. Rubber Industry:

Used in rubber products such as tires and seals, it delays the thermal and oxidative aging of rubber, protecting its elasticity and mechanical properties during processing and long-term use, and reducing performance degradation under high-temperature environments.

8. Other Polymer Materials:

It can also be used in other resins (such as epoxy resins) and composite materials, playing a role in resisting thermal and oxidative aging and protecting color in the processing and application of various polymer materials, ensuring the long-term stability of the materials.
