Sigma Switches to Biomass-Derived Polycarbonate Resin as Part of its Commitment to More Sustainable Manufacturing

We are pleased to announce that Sigma is advancing its commitment to sustainability by switching from a conventional petroleum-based resin to a biomass-derived alternative for the production of its proprietary material, Thermally Stable Composite (TSC). This shift significantly reduces the environmental impact of Sigma’s manufacturing processes.
