How does polyethylene handle exposure to pet urine?

Polyethylene, a widely used plastic, exhibits strong resistance to pet urine due to its non-porous and chemically inert nature. This synthetic polymer repels liquids, preventing absorption and minimizing odor retention. Its molecular structure resists breakdown from urea and ammonia in urine, making it ideal for pet products like training pads, litter boxes, and waterproof liners. High-density polyethylene (HDPE) offers superior durability against prolonged exposure, while low-density variants maintain flexibility. For optimal performance, choose polyethylene products with smooth surfaces for easy cleaning. Regular maintenance still recommended despite its resistance properties.
