High-density polyethylene (HDPE) is widely used in pipes, geotechnical materials, aquaculture facilities, outdoor and agricultural plastic products due to its high crystallinity, corrosion resistance, low-temperature resistance, and ease of processing.

Water-based textile coating preservatives and bactericides are chemical additives used in water-based textile coatings. They can effectively kill or inhibit microorganisms (including bacteria, fungi and algae, etc.) in the coatings, prevent the coatings from being contaminated and decaying, thereby extending the service life of the coatings and maintaining their stable performance.

The processing temperature of PPR pipes is relatively high (usually 200-260°C), so high-temperature resistant and stable antibacterial agents need to be selected. Inorganic antibacterial agent
