Material Notes:
Hostaform® acetal copolymer grade LM140LG is a laser markable specialty grade of acetal copolymer formulated to provide good flow with a low gloss finish.laser markable, low gloss, good flowStandard reciprocating screw injection molding machines with a high compression screw (minimum 3:1 and preferably 4:1) and low back pressure (0.35 Mpa/50 PSI) are favored. Using a low compression screw (I.E. general purpose 2:1 compression ratio) can resuInformation provided by Celanese
