Static discharge polymer for rebreather

An electrical static discharge polymer has been used on a rebreather to make a grounding path to stop the build up of static charge in plastic resin, which can cause potentially deadly sparks.

Materials giant, Sabic, used its FARADEX compound which incorporates conductive stainless steel fibres throughout its base material to help dissipate static charges. Because the conductive property permeates the entire part, it helps to provide consistent protection, as the conductivity cannot be disrupted by surface scratches or nicks.

As the base material, LEXAN EXL copolymer offers superior impact and low temperature ductility, as well as enhanced processability, compared to standard PC grades. All LNP FARADEX compounds are Restriction of Hazardous Substances (RoHS) compliant, and grades based on non-brominated, non-chlorinated and flame retardant systems are available.
