What are the differences between outdoor-rated and indoor-grade WPC for sculptures?

When choosing Wood-Plastic Composite (WPC) for sculptures, understanding the differences between outdoor-rated and indoor-grade options is crucial. Outdoor-rated WPC is designed to withstand harsh weather conditions, including UV rays, moisture, and temperature fluctuations. It typically contains higher levels of plastic and additives for enhanced durability and resistance to mold, rot, and fading.

Indoor-grade WPC, on the other hand, prioritizes aesthetics and ease of shaping but lacks the robust weatherproofing of outdoor variants. It’s ideal for controlled environments where exposure to elements is minimal. Key differences include:

1. Durability: Outdoor WPC is more resilient to environmental stress.

2. Composition: Outdoor grades have higher plastic content for waterproofing.

3. Maintenance: Indoor WPC requires less upkeep but isn’t suited for outdoor use.

4. Cost: Outdoor-rated WPC is often more expensive due to specialized additives.

For long-lasting outdoor sculptures, opt for outdoor-rated WPC, while indoor-grade WPC works best for decorative, protected pieces. Always check manufacturer specifications to ensure suitability for your project.
