2 These raw materials have out-standing resistance to both physical and chemical attack. The following chart should be used as a guidefor evaluating the suitability of our products with the chemical agent you plan to use. Special considera-tion must be given to the expected service temperature, stress involved in the application, as well as thelength and type of exposure ( intermittent or continuous).CDF Technical MemoNumber 1 July 2004# Plasticizer. Certain types of chemicals areabsorbed to varying degrees by poly-ethylene causing swelling, weight-gain,softening and some loss of yieldstrength.

3 These plasticizing materialscause no actual chemical degrada-tion of the resin. Several of thesechemicals have a strong plasticizingeffect ( aromatic hydrocarbonsbenzene), whereas others have weakereffects ( gasoline). Certain plasti-cizers are sufficiently volatile that ifthey are removed from contact withthe polyethylene, the part will dry outand return to its original condition withno loss of properties.+ are the only group of materi-als capable of chemically degradingpolyethylene. The effects on the poly-ethylene may be gradual even forstrong oxidizers and short-term effectsmay not be measurable.
