One could easily check if HDPE had any plasticizers or waxes added by simply cutting a small piece off and putting into some water and heating it. If I remeber right pure HDPE melts right at the boiling point of water. Anyway, the following addatives are often added to HDPE: heat and light stabilizers (light stabilizers are usually either carbon black or UV absorbers) slip agents (typically an amide) antiblock agents antistaic agents (primary purpose is to reduce static and dust pickup) flame retardants pigments Marshall -- The silver-list is a moderated forum for discussion of colloidal silver.
