LDPE & HDPE resistance listed by chemical 1.4-dioxane LDPE / HDPE at 20C° show little or no damage after 30 days. The absence of branching results in a more closely packed structure with a higher density and somewhat higher chemical resistance than LDPE. For polyethylene, arguably the simplest polymer, this is demonstrated by the following equation. HDPE. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. The high density polyethylene (PEAD) is a semi-crystalline thermoplastic polymer. HDPE provides a whole host of benefits to manufacturers, retailers and consumers. Table 2.
