IMPORTANT INFORMATION

• Coefficient of thermal expansion is over 10 times that of DI and steel and 3 times that of PVC. In practical terms, this means HDPE pipe shrinks 10 times as much as DI and 3 times as much as PVC when it gets cold. This can loosen any fittings installed on it. Also, it’s length shrinks 1 inch per 100 feet of pipe length with a 10° F

How much does HDPE sheet expand and contract? iPoly

HDPE sheet expands more in length than in width, due to its molecular structure. The easiest formula to use for an exact expansion / contraction dimension is as follows Degrees Fahrenheit 0.00011 x degree variance(°F) x length in inches Example 0.00011 x 30°F temperature change x 96" long sheet = 0.3168" or approximately 5/16" Degrees Celsius:
