What are the raw materials for wpc decking？

The **raw materials for WPC (Wood Plastic Composite) decking** include a blend of wood fibers and plastics, combined with various additives to enhance durability, stability, and appearance. Here’s a detailed breakdown of each type of raw material used:

### 1. **Wood Fibers/Filler**
– **Types**: Common sources include sawdust, wood chips, wood flour, or other cellulose-based materials.
– **Function**: The wood fibers provide WPC decking with the natural look and texture of wood, while adding structural strength.
– **Environmental Aspect**: Wood fibers often come from recycled or waste wood products, making WPC decking an eco-friendly choice by reducing reliance on virgin wood.

### 2. **Plastic/Polymer Matrix**
– **Types of Plastics**: WPC decking commonly uses:
– **High-Density Polyethylene (HDPE)**: Known for its strength and flexibility, often derived from recycled plastics like milk jugs and plastic bags.
– **Polypropylene (PP)**: Offers a higher melting point, adding durability and temperature resistance.
– **Polyvinyl Chloride (PVC)**: Sometimes used for added durability and water resistance, especially in outdoor applications.
– **Function**: The plastic component provides WPC decking with moisture resistance, durability, and flexibility. It also helps bind the wood fibers, giving the composite its structural integrity.

### 3. **Additives**
– **Color Pigments**: Added to achieve desired color and UV resistance, pigments help maintain the decking’s appearance over time.
– **UV Stabilizers**: Protect the decking from ultraviolet light, reducing fading and degradation caused by prolonged sun exposure.
– **Antioxidants**: Help prevent oxidation and degradation of the plastic matrix, extending the lifespan of the decking.
– **Coupling Agents**: Enhance the bonding between wood fibers and plastic, improving structural integrity and durability.
– **Anti-Microbial/Fungal Agents**: Added to prevent mold, mildew, and fungal growth, especially important in humid climates.
– **Lubricants**: Improve the flow of materials during the extrusion process, ensuring a smooth, consistent finish.

### 4. **Optional Surface Coatings or Treatments**
– **Protective Coatings**: Some WPC decking includes a co-extruded cap layer, which is an extra layer of polymer that enhances resistance to scratching, staining, and fading.
– **Embossing**: Surface embossing can be applied to create wood-like textures, making the decking look and feel more like natural wood.

These combined raw materials ensure that WPC decking is a durable, eco-friendly, and low-maintenance option for outdoor spaces.

 

What is the ratio of wood powder to plastic in wood plastic decking？

In **Wood Plastic Composite (WPC) decking**, the ratio of wood powder (or wood fibers) to plastic generally ranges between **40:60** and **60:40**, depending on the desired properties of the final product. Here’s a more detailed breakdown of typical ratios and their effects:

1. **50:50 Ratio (Wood:Plastic)**
– **Most Common Ratio**: This balanced ratio offers a good compromise between the appearance and strength of wood and the durability and moisture resistance of plastic.
– **Properties**: Moderate weight, good water resistance, and strength suitable for most decking applications.

2. **60:40 Ratio (Wood:Plastic)**
– **Higher Wood Content**: Gives the decking a more natural wood appearance and texture.
– **Properties**: Feels more like wood and may be slightly more eco-friendly with increased renewable content. However, slightly more susceptible to moisture than lower wood-content ratios.

3. **40:60 Ratio (Wood:Plastic)**
– **Higher Plastic Content**: Offers enhanced water resistance, flexibility, and durability, especially suited for humid or wet environments.
– **Properties**: Less wood-like in texture but more resilient to decay, mold, and UV damage.

The exact ratio depends on factors such as desired appearance, environmental conditions, and specific performance requirements.

– **Thinner Boards (e.g., 12-20 mm)**
– **Cost-Effective**: Lightweight, easier to install, and more affordable, though less suited for high-traffic areas.
– **Flexibility**: Easier to cut and shape for custom installations, but may not be as durable for long-term use.

### 5. **Surface Texture**
– **Smooth Texture**
– **Easy to Clean**: Easier to maintain but can become slippery when wet.
– **Minimal Wood Appearance**: More modern aesthetic but lacks a natural wood feel.
– **Textured/Embossed Grain**
– **Slip Resistance**: Provides better grip underfoot, even when wet, making it ideal for poolside or outdoor use.
– **Natural Look**: Mimics the look of wood grain, enhancing visual appeal.

### **Summary of Performance Differences by Model**
– **Solid vs. Hollow Core**: Solid is more durable; hollow is lighter and more cost-effective.
– **Co-extruded vs. Non-Co-extruded**: Co-extruded offers more protection and durability; non-co-extruded is less expensive.
– **Wood-to-Plastic Ratio**: Higher wood content looks more natural; higher plastic content improves durability.
