Test standards: Type V tensile specimens (10 mm/min crosshead speed); ASTM D790 flexural (14:1 span ratio, 1 mm/min). Formulation: PA 66 masterbatch with 1 wt.% Flexiphene™ dispersion.
Nanocarbon particles want to clump together. When they do, you lose the high surface-area contact that drives reinforcement — and introduce stress concentration points that actually weaken the matrix. Flexiphene™ was engineered from the ground up to solve this.
Result: Marginal gains, high loading, and production inconsistency
Result: Reliable double-digit gains at low loading, every batch
Effective polymer reinforcement requires three things: uniform distribution, intact nanocarbon structure, and a clean polymer interface. Flexiphene™ delivers all three through patented surface engineering.
Proprietary surface chemistry keeps nanocarbon particles separated at the molecular level throughout the polymer matrix — no agglomeration means every particle contributes to reinforcement. SEM-verified.
High-aspect-ratio nanotubes and graphene sheets remain structurally intact — never acid-oxidized. Longer fibrous structures bridge across greater distances in the matrix for superior load transfer efficiency.
Zero surfactant residue means the nanocarbon-polymer interface is chemically clean. Load transfers directly from matrix to carbon, not through a soft surfactant layer that dampens stress transmission.
Because every particle is active (not clustered), you achieve double-digit gains at 1 wt.% loading. Higher loadings can reach diminishing returns — Flexiphene™ delivers peak efficiency at low addition levels.
Validated in PA 66, epoxy, polyurethane, PEEK, silicone, and TPU systems. Our materials scientists can recommend the optimal dispersion protocol for your specific polymer processing conditions.
Shipped as a liquid dispersion — no powder handling, no hazardous dust exposure, no special mixing equipment. Integrates into melt compounding, solution casting, and resin infusion workflows.
Double-digit strength gains at low loading opens up new design space across industries where weight, performance, and reliability are non-negotiable.
Higher heat-resistant structural rigidity in PA 66 engine bay components without increasing weight or part thickness. Enables lightweighting through material performance gains.
Reinforced thermoplastic brackets, housings, and secondary structural panels where every gram matters and part failure isn't an option. ASTM test data supports design specification.
Enhanced structural integrity in PEEK and biocompatible polymer enclosures for implantable devices and surgical instruments. Surfactant-free formulation supports clean-room compatibility.
Reinforced filament formulations for FDM and SLS printing in engineering applications. Improved interlayer strength and stiffness in complex geometries where printed parts must bear real loads.
Enhanced wear resistance and load-bearing capacity in PA and PEEK mechanical components for pumps, conveyors, and precision machinery operating under continuous stress.
Toughened epoxy and vinyl ester matrices for sporting goods, marine, and wind energy applications where fatigue resistance and impact toughness determine product lifetime.
