Also announced are two new Edgetek™ PKE non-halogen flame retardant (NHFR) formulations made with polyketone, which can have a lower carbon footprint compared to polyamide 6 reinforced materials, and are pre-colored in orange for high-voltage connectors in electric vehicles. Also announced will be the availability of two new Edgetek™ PKE polyketone (PK) grades with non-halogen flame retardants (NHFRs). 

Most GLS materials overmolding materials are generally non-abrasive / non-corrosive and replicate the mold surface fairly well.
