Wellamid® MR340 42H-N

Technical Datasheet | Supplied by Wellman Engineering Resins (PRET)

Wellamid® MR340 42H-N is a polyamide 6 grade reinforced with 34% particulate and fibrous shaped mineral fiber. Addition of mineral increases the HDT and reduces cycle time when compared to unfilled nylon. Exhibits improved dimensional stability and stiffness at elevated temperatures. Increased stiffness reduces drag resistance seen during mold ejection and allows the injection molded article to be ejected sooner during processing. Used in automotive wheel covers and for painted parts.
