Description
PE (polyethylene) describes a huge family of resins obtained by polymerizing ethylene gas, H2C=CH2. It is by far the largest volume commercial polymer.
This thermoplastic is available in a range of flexibilities and other properties depending on the production process, with high density materials being the most rigid. PE can be formed by a wide variety of thermoplastic processing methods and is particularly useful where moisture resistance and low cost are required.
Low density PE typically has a density value ranging from 0.91 to 0.925 g/cm³, linear low density polyethylene is in the range of 0.918 to 0.94 g/cm³, while high density polyethylene ranges from 0.935 to 0.96 g/cm³ and above.
