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:
