CERTENE™ SGM-140

About
CERTENE™ SGM-140 SGM-140 is a certified prime grade specially developed for INJECTION MOLDING thin-wall applications requiring easy mold filling and good overall properties. SGM-140 is a multipurpose low molecular weight resin that offers superior flexural strength, outstanding clarity, exceptional high-flow processability, fast injection cycling, fast filling long flow paths of intricate mold geometry with minimal stresses in moldings. SGM-140 applications include thin-walled containers, cutlery, vials, jars, tumblers, disposable medical ware, audio and video cassette boxes, and toys. SGM-140 complies with FDA regulation 21CFR 177.1640 and with most international regulations concerning the use of Polystyrene in contact with food articles.&&CERTENE™ SGM-140 SGM-140 is a certified prime grade specially developed for INJECTION MOLDING thin-walled applications requiring easy mold filling and good overall properties.
