Polyethylene Properties - pipe in Mexico

The first PE pipe material used in engineering appliions was Type 50 High Density PE (HDPE) with a long term stress of 50MPa. Subsequently, Medium Density (MDPE) materials, with improved pipe properties when compared to the earlier high density materials, were used in pipes due to their improved flexibility, ductility, slow crack growth resistance and crack propagation resistance.

How much does HDPE sheet expand and contract? | iPoly

For outdoor aient temperature appliions, the rule of thu is that a 4 x 8 sheet will expand as much as 1/2" in length from a hot summer day to sub-zero winter temperatures in cold climates. 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 Puhui Pipe manufacturer in China
