The flooding in plastic-critical Texas reminded me that water-resistant plastic products—boats, tarps, bags of all kinds—are saving a lot of property and even lives, but in extrusion, as in Houston and Florida, water is often an enemy.
This happens in one of two ways (or both):
Cosmetic—water absorbed by the resin will boil to steam as it leaves the die, and make bubbles, pits or dotted lines on the product surface. It gets well above 100° C (212° F) inside the extruder, but pressures are too high to permit boiling and the water stays in liquid form until its pressure drops as it passes through the die lips.
