Antioxidant PEPQ Application scenarios

1. Polyolefin Processing Stabilization:

Compatible with PP, HDPE, LLDPE, EVA, etc., inhibiting thermo-oxidative degradation and yellowing during extrusion/injection molding/blown film production, stabilizing melt flow rate, suitable for thin-walled containers, agricultural films, and pipes. Better when combined with antioxidant 1010.

2. Engineering Plastics High-Temperature Stabilization:

Used in PC, PA, POM, PET, PBT, etc., preventing degradation and discoloration during high-temperature molding, suitable for electronic components and automotive interior parts, improving long-term heat resistance.

3. Styrene-Based Resins Anti-Aging:

Used in PS, ABS, AS, etc., inhibiting oxidative yellowing and impact strength reduction during processing and use, suitable for appliance casings and office supplies, especially suitable for white/light-colored products.

4. Anti-aging of Elastomers and Rubber:

Used in thermoplastic elastomers such as natural rubber, styrene-butadiene rubber, nitrile rubber, neoprene, and SEBS/SBS ​​to inhibit thermo-oxidative aging and ozone cracking. Suitable for seals and conveyor belts, and synergistically enhanced when combined with antioxidants.

5. Stabilization of Food Contact Materials:

Used in food contact containers, films, and caps such as PP and PE to prevent packaging aging and food contamination.

6. Synthetic Fiber Spinning Protection:

Used in synthetic fibers such as polyester and nylon to prevent thermo-oxidative degradation during spinning and post-processing, maintaining fiber strength and whiteness. Suitable for clothing and industrial yarns.

7. Antioxidant Properties in Coatings and Inks:

Added to solvent-based coatings, powder coatings, and oil-based inks to inhibit resin and pigment oxidation, preventing discoloration, loss of gloss, and clumping during storage and use, and extending shelf life.

8. Adhesive and Sealant Stabilization:

Used in epoxy, polyurethane, acrylic, and other adhesives and sealants to prevent oxidation during curing and use, improving bond strength and aging resistance. Suitable for the construction and automotive industries.

9. Wire and Cable Insulation Protection:

Used in PVC, PE, PP, and other wire and cable insulation and sheathing materials to inhibit thermo-oxidative degradation and copper-catalyzed aging, improving long-term safety.
