Over 11 million U.S. homes rely on toxic lead pipes. Bioderived polyethylene offers a safer replacement, but long-term durability must be ensured. This research studies how chlorine degrades pipe materials and how molecular branching improves resilience. Accelerated aging tests link polymer structure to performance, guiding design of longer-lasting, reliable water infrastructure.

Millions of U.S. homes still rely on lead pipes, prompting a shift toward bimodal polyethylene replacements. This research examines how molecular branching affects pipe durability under chlorinated conditions. Using accelerated aging tests, it links polymer structure to long-term performance, guiding the design of safer, longer-lasting water pipes for future infrastructure.
