FLEXRESIST

                                                                                      The Company   

• FlexResist LLC is an advanced carbon technologies company based in Underwood, North Dakota. We develop novel carbon materials derived from the Fort Union lignite formation — one of the largest untapped structured carbon resources in the world. 

                                                                                      The Material    

• North Dakota's Paleocene-age lignite contains something no other carbon source offers: preserved biological microstructure from 60-million-year-old forests. When carbonized under controlled conditions, this material retains the hierarchical pore architecture of the original plant vascular tissue — directional channels, nanoscale membranes, and multi-scale porosity that cannot be synthesized artificially.
• The result is a structured, anisotropic carbon platform with applications across filtration, tribology, advanced ceramics, composite reinforcement, energy storage, and soil amendment.                        

                                                                                     The Advantage 

• Every existing commercial carbon material — activated carbon, carbon black, graphite, carbon fiber, biochar — has either random pore structure or no pore structure at all. FlexResist's carbonized xyloid lignite is the first carbon material whose internal architecture is determined by preserved biology rather than by chemical processing.
• Sixty million years of geological pre-processing did the work. We just unlock it. 

                                                                                 Applications 

• Water Filtration — Directional pore channels reduce pressure drop and improve PFAS removal kinetics over conventional granular activated carbon. 
• Advanced Ceramics — Biomorphic silicon carbide templates with anisotropic strength properties inherited from the biological precursor. 
• Tribology — Sustained-release micro-reservoir lubrication from preserved xylem channels. 
• Composite Reinforcement — Biologically shaped carbon fragments providing anisotropic reinforcement in polymer matrices. 
• Energy Storage — Hierarchical pore architecture for supercapacitor and battery electrode applications. 
• Soil Amendment — Structured biochar with fungal-scale habitat channels and multi-century carbon permanence.
