What are the differences in resistance to animal urine between PVC and polyethylene?

When comparing PVC and polyethylene for resistance to animal urine, several key differences emerge. PVC (Polyvinyl Chloride) is known for its excellent chemical resistance, including against acidic and alkaline substances found in animal urine. Its rigid structure and non-porous surface make it highly resistant to staining and odor absorption.

Polyethylene, on the other hand, is more flexible but generally less resistant to harsh chemicals. While it can withstand mild exposure, prolonged contact with animal urine may cause degradation over time, especially in lower-density variants. High-density polyethylene (HDPE) offers better resistance but still falls short of PVC's durability.

For applications like pet enclosures, flooring, or outdoor furniture, PVC is often the superior choice due to its long-term resilience. Polyethylene may be suitable for temporary or low-exposure uses but requires more frequent replacement in high-urine environments. Always consider the specific grade and additives in each material, as these can significantly impact performance.
