Outdoor PVC & Rubber Weather Resistance Solutions

Protect Outdoor PVC & Rubber Products from UV, Heat and Weathering

Outdoor plastic and rubber products are constantly exposed to sunlight, oxygen, moisture, temperature fluctuations and environmental pollutants. Without effective stabilization, these materials gradually lose their mechanical properties and appearance, resulting in discoloration, cracking, embrittlement and premature failure.

Yihoo Polymer offers comprehensive weather-resistant additive solutions for PVC, EPDM, TPE, TPV and other rubber and plastic materials. Our customized antioxidant, UV absorber and HALS technologies help manufacturers produce durable products with longer service life and lower maintenance costs.

Industry Challenges

Environmental Exposure Accelerates Material Degradation

Degradation Mechanisms & Problems

Outdoor materials experience continuous environmental stress throughout their service life. Common degradation mechanisms include photo-oxidation, thermal oxidation and ozone attack, which gradually reduce product performance.

Typical problems include:

  • Surface chalking
  • UV-induced discoloration
  • Color fading
  • Loss of gloss
  • Cracking and embrittlement
  • Reduced tensile strength
  • Poor flexibility at elevated temperatures
  • Premature aging
  • Shortened outdoor service life

Long-Term Exposure Demands

Manufacturers require stabilization systems capable of maintaining both appearance and mechanical performance under long-term outdoor exposure.

Yihoo Polymer Solution

Multi-Layer Protection Against Outdoor Aging

UV Absorption

Our UV absorbers absorb harmful ultraviolet radiation before it damages polymer chains, reducing fading and extending product life.

HALS Protection

HALS continuously capture free radicals generated during UV exposure, providing long-lasting resistance against photo-oxidation.

Thermal Stabilization

Primary and secondary antioxidants prevent oxidation during processing and long-term outdoor use, helping maintain strength and flexibility.

Color Stability

Special additive combinations preserve the original appearance of colored and white products even after prolonged outdoor exposure.

Processing Improvement

Optimized stabilization packages enhance melt stability, reduce degradation during extrusion and improve production consistency.

Frequently Asked Questions

Find answers to common questions about our outdoor weather resistance solutions.

Prolonged exposure to UV radiation, heat and oxygen causes polymer chain degradation, resulting in embrittlement and cracking. Proper stabilization significantly delays this process.
UV absorbers filter harmful ultraviolet light before it reaches the polymer, while HALS interrupt the free-radical degradation cycle. Combining both technologies delivers superior long-term weather resistance.
Our additives are widely used in PVC profiles, roofing membranes, cable insulation, rubber seals, outdoor furniture, playground equipment and solar components.
Yes. We develop formulations based on polymer type, processing conditions and expected service environment.
Yes. Our stabilization systems help preserve color consistency and reduce fading over extended outdoor exposure.
Yes. Proper antioxidant systems improve melt stability, reduce degradation during processing and enhance production efficiency.
