What additives are used in WPC to improve resistance to mold and mildew?

Wood-Plastic Composite (WPC) is a popular material due to its durability and eco-friendly properties. However, to enhance its resistance to mold and mildew, specific additives are incorporated during manufacturing. Common additives include:

1. Biocides: These chemicals inhibit the growth of mold and mildew, ensuring long-term protection.

2. Zinc Borate: A natural fungicide that prevents fungal growth and improves fire resistance.

3. Silver-Based Additives: Known for their antimicrobial properties, they help combat mold and bacteria.

4. UV Stabilizers: While primarily for sun protection, they also reduce moisture absorption, limiting mold growth.

5. Water Repellents: Silicone or wax-based additives reduce water absorption, a key factor in mold development.

By integrating these additives, WPC maintains its structural integrity and aesthetic appeal, even in humid or wet environments. This makes it an ideal choice for outdoor applications like decking and fencing.
