Antioxidant 618 Application scenarios
1. Polyoléfines
Polyethylene (PE), Polypropylene (PP) processing stabilizer, improves initial coloring, prevents thermal oxidative degradation.
2. Plastiques techniques
ABS resin, Polystyrene (PS/HIPS), Polycarbonate (PC), Polyester (PET/PBT) maintain color stability and improve stability during thermal processing.
3. Vinyl Polymers
Polyvinyl chloride (PVC), Ethylene-vinyl acetate copolymer (EVA) auxiliary stabilizer, improves color.
4. Elastomers and Coatings
Various elastomers, coatings, inks prevent oxidation and extend material lifespan.
📜 Special Applications: Food Contact Materials
A key advantage of antioxidant 618 is its compliance. It has low toxicity, is FDA-approved, and complies with Chinese National Standard GB 9685-2016, allowing its use in food contact materials. For example, its maximum usage in PVC food packaging materials is 1%. It is often used to replace traditional antioxidants such as BHT.
