WebOct 26, 2012 · Let’s use HDPE sheet extrusion as an illustration, where the average melt-temperature range is 400-450 F. If you take 425 F as an average melt temperature, and the polymer goes into the extruder at room temperature (75 F), the change in temperature is 350° F. We know the average specific heat of HDPE is 0.55 BTU/lb-°F. High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes and plastic lumber. HDPE is commonly recycled, and has the number "2" as its resin identification code. northern tool wood burning stove
