High Density Polyethylene (HDPE)
Custom HDPE Fittings
Characteristics of HDPE
HDPE is a durable, flexible plastic. The insoluble material is weather-resistant, shock-resistant, and abrasion-resistant. HDPE is also highly affordable, created from petroleum under high heat. Rather than crack, HDPE is more likely to tear under pressure, reducing overall damage. 100% BPA-free, HDPE is the favored material in the food industry. It is often selected for industrial work as it is 250% thicker than PVC. The material is also recyclable, producing useful if less sturdy plastic. The trickiest factor when working with HDPE is bonding, which requires intense heat and precision.
