Soarce Closes $5M Seed Round Led by Collab Capital
We closed a $5 million seed round last week. Collab Capital led the round. The capital goes toward a second electrospinning line, a dedicated compounding line, and raw material supply agreements...
Nanocellulose vs. Glass Fiber: A Weight Comparison at Equal Stiffness
We tested NC-200 against standard E-glass short fiber in a polypropylene matrix. At matched flexural modulus, the NC-200 compound showed 38% lower density...
Five Lessons from Scaling Electrospinning to Production Volumes
Moving from lab-scale needleless electrospinning to 120+ square meters per hour forced us to rethink humidity control, collector speed, and solvent recovery...
How We Test Thermal Stability: ASTM E2550 Protocol at Soarce
Thermal decomposition onset temperature matters for any composite near engines or heated tooling. Here is exactly how we measure it and what the numbers mean...
Getting CNC Dispersion Right in a Twin-Screw Extruder
Agglomeration kills performance. We share our screw profile, feed rate settings, and barrel temperature zones for achieving uniform CNC dispersion in PA6...
Where Our Nanocellulose Comes From: Wood Pulp Sourcing in the Southeast
Traceability matters. We source dissolving-grade pulp from two FSC-certified mills in the Carolinas. Here is our supply chain from forest to nanocrystal...
Injection Molding with Nanofiber Composites: Process Window Guide
NF-400 pellets run on standard PA6 barrel temperatures. We document melt temperature, injection pressure, and hold time adjustments for fiber-reinforced grades...
Nanofiber Filtration Membranes: Pore Size Control Through Process Parameters
Fiber diameter and mat basis weight determine membrane pore size. We document the relationship with production data from NF-200, NF-400, and NF-600 grades...
Comparing Nanocellulose and Carbon Fiber: Cost Per Unit Stiffness
Carbon fiber wins on absolute performance. But on a dollar-per-GPa basis, NC-200 is competitive — and for applications needing 4-7 GPa, it costs 35-55% less...
Surface Treatment of Nanocellulose: Why Silane Coupling Agents Matter
Untreated cellulose bonds poorly to hydrophobic polymers. APTES silane treatment improved NC-200/PA6 flexural strength by 22% — enough to pass automotive qualification...
Compression Molding Nanofiber Mats into Thermoset Panels
NF-400 mats work with standard wet layup and compression molding processes. We document the layup procedure, press parameters, and resulting panel properties...
Moisture Sensitivity in Nanocellulose Composites: Testing and Mitigation
Cellulose absorbs water. We measured moisture uptake and property retention at 50% RH, 95% RH, and water immersion for NC-200 in PP and PA6 matrices...
Automotive Material Qualification: What OEMs Actually Require
OEMs do not buy materials based on data sheets. The qualification process takes 12-24 months and costs $50,000-150,000 in testing and documentation. Here is what it involves...
