What are the best methods to test WPC for resistance to chewing by rodents?

Testing wood-plastic composite (WPC) materials for resistance to rodent chewing is essential for ensuring durability in pest-prone environments. The most effective methods include:

1. ASTM D1758 Standard Test: This lab procedure evaluates WPC's resistance to termites and rodents by exposing samples to controlled pest activity.

2. Field Trials: Installing WPC in real-world rodent-infested areas to monitor long-term damage.

3. Accelerated Lab Tests: Simulating rodent chewing using mechanical abrasion or synthetic gnawing tools.

4. Material Hardness Analysis: Measuring surface hardness (e.g., Shore D scale) to predict resistance.

5. Additive Testing: Incorporating repellent additives (e.g., capsaicin) and assessing their efficacy.

Combining these methods ensures comprehensive evaluation, helping manufacturers develop rodent-resistant WPC products.
