AD-304 is incorporated into resin to reduce UV-related degradation of the polymer. Its primary role is not to add color or guarantee shade stability.

Where it may fit

  • Outdoor plastic parts
  • Products routinely exposed to sunlight
  • Applications seeking to reduce yellowing, gloss loss, or brittleness

Documented resins and processes

Published compatibility is a starting point, not automatic approval of the finished part.

Resins

  • High-density polyethylene (HDPE)
  • Low-density polyethylene (LDPE)
  • Linear low-density polyethylene (LLDPE)
  • Polypropylene (PP)
  • General-purpose and impact polystyrene
  • Rigid and flexible PVC compounds
  • Solid TPU
  • EVA
  • SAN

Processes

  • Injection molding
  • Extrusion
  • Blow molding
  • Thermoforming

What the formulation contributes

  • Microsphere presentation
  • Use across several processes
  • Focused on protection of the polymer structure

Before selecting the grade

Define the resin, process, wall thickness, target appearance, and acceptance method. A sample in a different material does not replace a production-representative trial.

Limits to respect:
  • It does not replace weathering evaluation of the finished part.
  • It should not be described as a color-protection additive.
  • Compatibility and dosage must be confirmed through a process trial.
