Why do decorative rats have a smell?

Why do decorative rats have a smell? - briefly

They are typically composed of polymer resins, adhesives, or coatings that release volatile compounds, and residual chemicals from production can linger as an odor. Improper storage may allow mold or mildew growth, further intensifying the smell.

Why do decorative rats have a smell? - in detail

Decorative rodent figures often emit an odor because of the substances used in their production. The scent originates from several sources:

  • Polymer additives: Plastics such as PVC and ABS contain plasticizers, stabilizers, and flame‑retardant chemicals that release volatile organic compounds (VOCs) over time.
  • Adhesives and coatings: Glue, epoxy, and clear coats applied to enhance appearance frequently contain solvents that evaporate slowly, leaving a detectable smell.
  • Molded resin residues: During injection molding, residual monomers and curing agents can remain trapped in the material, gradually off‑gassing.
  • Packaging materials: Cardboard, foam inserts, and scented packaging liners may transfer odors to the product during storage and transport.
  • Environmental exposure: Prolonged contact with humidity, heat, or sunlight accelerates degradation of the aforementioned chemicals, intensifying the odor.

Manufacturers sometimes add fragrance to mask unpleasant smells, but the underlying chemical emissions persist. Cleaning the items with mild soap and water, followed by airing them in a well‑ventilated area, reduces the intensity of the odor. For long‑term mitigation, storing the figures in sealed, low‑temperature containers limits VOC release.
