How do manufacturers address thermal degradation of WPC in outdoor sofa production?

Thermal degradation is a critical challenge in Wood-Plastic Composite (WPC) outdoor sofas, as prolonged exposure to sunlight and heat can weaken the material. Manufacturers employ several strategies to mitigate this issue:

1. UV Stabilizers: Adding UV-resistant additives to WPC formulations helps block harmful rays, reducing surface cracking and fading.

2. Heat-Resistant Polymers: Using high-quality polymers with higher melting points enhances the material's ability to withstand elevated temperatures.

3. Protective Coatings: Applying specialized coatings shields WPC from direct sunlight and moisture, prolonging its lifespan.

4. Material Blending: Incorporating mineral fillers or fiber reinforcements improves thermal stability and structural integrity.

5. Design Adjustments: Ventilated designs and lighter colors minimize heat absorption, reducing thermal stress on the material.

By combining these methods, manufacturers ensure WPC outdoor sofas remain durable and aesthetically pleasing even in harsh weather conditions.
