http://www.imtechdesign.com/advice_materials_pe_hd.php WebHDPE has less side branching than LDPE resulting in a denser 3-D structure. As a result, HDPE is less flexible than LDPE and melts at a higher temperature (120°C). Like other polyolefins, HDPE is chemically inert. Strong oxidizing agents will eventually cause oxidation and embrittlement. HDPE has no solvent at room temperature.
