High density polyethylene temperature range
WebIn general, high density grades of polyethylene have densities up to 0.97 g/cm^. Low density grades are as low as 0.91 g/cm^. Typically, the high-density material is more linear and consequently more crystalline. As might be expected, this higher crystallinity permits use at temperatures up to 130 C with somewhat better creep resistance below ...
