UV-2908 Application scenarios

1. Polyolefin Products:

Suitable for PE (films, flat fibers, pipes, rotational molded containers) and PP (flat fibers, injection molded parts, sheets), preventing photo-oxidative aging, discoloration, and embrittlement of products. Especially suitable for colored and opaque products.

2. Engineering Plastics:

Used in PET, PBT, PC, flexible PVC, TPO, etc., to improve weather resistance and thermal processing stability, particularly suitable for formulations containing flame retardants.

3. Flame-Retardant Plastics:

In flame-retardant polyolefins (such as flame-retardant PE/PP pipes and electrical enclosures), it can synergize with flame retardants to reduce the impact of photo-oxidative degradation on flame retardancy.

4. Coatings and Inks:

In acrylic coatings, polyurethane coatings, and printing inks, it enhances the lightfastness of coatings and inks, preventing fading and chalking, and extending service life.

5. Adhesives and Sealants:

Suitable for polyolefin and acrylic adhesives and sealants, slowing down the decrease in bonding strength and aging caused by ultraviolet light, and improving durability.

6. Food Contact Materials:

Used in food packaging PE/PP films and containers, etc., complying with relevant safety standards, inhibiting material aging to ensure packaging integrity.

7. Cosmetics and Personal Care Products:

As an antioxidant and light stabilizer, used in sunscreens, anti-aging products, etc., protecting active ingredients in the formula and reducing photodegradation.

8. Synergistic Blends with Synthetic Material Additives:

Used in combination with benzophenone UV absorbers, phosphite antioxidants, and HALS, producing synergistic effects in plastics, coatings, and other systems to improve stabilization.
