Model PE PVC PP PS PC Anti-Yellowing Light Protection Additive UV Aborber for Plastics UV-531

Product Description

Product Overview

UV absorber is a "sun shield" for industrial materials, which prevents materials from aging due to light (e.g. plastic brittleness, coating discoloration, fiber strength decline) and extends outdoor service life by absorbing and converting UV energy. Its features include: high absorption (covering UVB/UVA bands), weather resistance (stable under long-term light exposure), good compatibility (no precipitation when combined with plastics, coatings, rubber, etc.), and safety and environmental protection (complying with industrial standards).
Core Uses:
Plastics: packaging film, automobile parts against yellowing;
Coatings: building exterior paint, automotive coatings anti-fading;
Fibers: outdoor fabrics, awnings anti-degradation;
Rubber: tires, seals anti-cracking.
Usage: directly mixed into raw materials (add 0.1%-2%), or dissolved in solvent and sprayed, need to be evenly dispersed. High-temperature processing select heat-resistant type (such as triazine).
Summary: UV absorber is a key additive to resist light aging, widely used in automotive, building materials, packaging and other fields, to ensure that the performance of the material in the outdoor environment in a durable and stable.

Application Guide

1. Plastic Products

Recommended Models: UV-531 (benzophenone), UV-326/327 (benzotriazole), UV-1577 (triazine)
Case Studies:

• Car Bumpers (PP/PE Materials):

  • Issue: Surface chalking and fading due to prolonged sun exposure.

  • Solution: Add 0.5%-1% UV-531 to plastic pellets for injection molding to enhance UV resistance.

• Outdoor Furniture (PVC):

  • Issue: UV-induced brittleness and discoloration.

  • Solution: Blend 1% UV-326 with PVC resin during extrusion to extend service life.

• Transparent PC Lamp Covers:

  • Issue: Yellowing and reduced light transmittance under UV exposure.

  • Solution: Incorporate 0.3% UV-1577 during injection molding to maintain clarity and weather resistance.

 

2. Coatings and Paints

Recommended Models: UV-9 (benzophenone), UV-1164 (triazine)
Case Studies:

• Architectural Exterior Paints (Acrylic Resin-Based):

  • Issue: Paint chalking and fading caused by UV radiation.

  • Solution: Add 1%-2% UV-9 to the paint formula for UV-protective coatings.

• Automotive Clear Coats (Polyurethane Systems):

  • Issue: Loss of gloss and cracking due to prolonged sunlight exposure.

  • Solution: Add 0.5% UV-1164 to enhance UV resistance and scratch durability.

 

3. Fibers and Textiles

Recommended Models: UV-P (benzotriazole), Nano-ZnO (inorganic)
Case Studies:

• Outdoor Sunshades (Polyester Fabric):

  • Issue: UV-induced fiber degradation and strength loss.

  • Solution: Add 0.8% UV-P to the spinning solution or apply a nano-ZnO coating.

• UV-Protective Clothing (Nylon/Spandex Blends):

  • Issue: Skin damage from UV penetration.

  • Solution: Blend 1% UV-P into fibers during production or apply nano-ZnO dispersion in post-treatment.

 

4. Rubber Products

Recommended Models: UV-327 (benzotriazole), UV-622 (HALS)
Case Studies:

• Car Tires (SBR Rubber):

  • Issue: Cracking due to combined ozone and UV exposure.

  • Solution: Use 0.5% UV-327 + 0.3% UV-622 synergistically to block photo-oxidation.

• Outdoor Seals (EPDM Rubber):

  • Issue: Loss of elasticity and sealing failure under prolonged UV exposure.

  • Solution: Add 1% UV-327 during rubber compounding to maintain flexibility and durability.

 

5. Packaging and Films

Recommended Models: UV-531, UV-326
Case Studies:

• Agricultural Greenhouse Films (LDPE):

  • Issue: Film aging and reduced light transmittance due to UV radiation.

  • Solution: Add 1% UV-531 to extend film lifespan to over 3 years.

• Food Packaging Films (BOPP):

  • Issue: Fading of printed patterns and material brittleness under light exposure.

  • Solution: Incorporate 0.3% UV-326 into masterbatch to preserve appearance and mechanical properties.

 

Key Usage Guidelines

1. Application Methods:

   • Direct Mixing: Blend powdered absorbers with raw materials (e.g., plastic pellets, rubber compounds).

   • Solvent Dissolution: Dissolve in solvents for liquid systems (e.g., coatings) before spraying.

2. Dosage: 0.1%-2% (adjust based on material thickness and UV exposure intensity).

3. Process Compatibility:

   • High-Temperature Processing (e.g., injection molding, vulcanization): Prioritize high-melting-point models (UV-327, UV-1577).

   • Transparent Materials: Use low-yellowing absorbers (UV-1577, UV-P).
