What are the differences in fire smoke toxicity between WPC and PVC-based planter materials?
When comparing WPC (Wood Plastic Composite) and PVC (Polyvinyl Chloride) planter materials, fire smoke toxicity is a critical factor to consider. PVC releases highly toxic fumes when burned, including hydrogen chloride and dioxins, which pose serious health and environmental risks. In contrast, WPC produces less toxic smoke, as it contains natural wood fibers mixed with plastics, reducing harmful emissions. While both materials are flammable, PVC's smoke is significantly more hazardous. For safety-conscious applications, WPC is often the preferred choice due to its lower toxicity profile during combustion. Always prioritize fire-resistant or non-toxic materials in high-risk environments.
