What additives are used to enhance the weather resistance of plastic outdoor rectangular tables?

Plastic outdoor rectangular tables are exposed to harsh weather conditions, including UV rays, rain, and temperature fluctuations. To enhance their weather resistance, manufacturers incorporate specific additives into the plastic material.

1. UV Stabilizers: These additives absorb or block harmful ultraviolet radiation, preventing discoloration, brittleness, and degradation caused by prolonged sun exposure.

2. Antioxidants: They protect the plastic from oxidative damage due to heat and oxygen, ensuring the table retains its strength and appearance over time.

3. Hindered Amine Light Stabilizers (HALS): These compounds slow down the photo-degradation process, extending the lifespan of the plastic table.

4. Pigments and Colorants: Certain pigments, like carbon black, provide additional UV protection while maintaining the table's aesthetic appeal.

5. Impact Modifiers: These improve the table's resistance to physical stress, such as cracking in cold weather.

By using these additives, plastic outdoor tables become more durable, fade-resistant, and capable of withstanding extreme weather conditions for years.
