Chemistry differences between PP, PLA, and PETG.

WebPolyethylene glycol (PEG) derivatives have been widely used in bio-related research. However, PEG oligomers (with different molecular weights) or PEG based monomers (with different chain end groups) actually have different chemical and physical properties, which might lead to potential toxicity. Web6.7.2 Chemical Resistance of Copolyesters. Copolyesters, like polyesters, possess very high chemical resistance and are used in applications like drug delivery, IV systems and components, luers, injection caps, and vials. PETG has a lower chemical resistance but better solvent and ultrasonic bondability than PCTG and PCTA (Fig. 6.44 ).
