Carbon Nanotube Product Forms

Product	Form	Typical use
JY series	Powder, 90 – 99% purity	Conductive additives, composite reinforcement
JCH series	Water-based conductive slurry	Energy storage, water-compatible coating
JCN series	NMP-based conductive slurry	Battery electrode slurries, solvent-borne systems

Ranges marked “confirmed per grade” are set by reinforcement and resin selection; send us your target specification and we confirm what we can supply.

Carbon nanotubes (CNT) are the nanoscale member of our product range. Added in small percentages to a polymer matrix, they form a conductive network that a single filler cannot achieve — which is what makes CNT masterbatch the standard solution for static dissipation and conductivity in thermoplastics.

Where CNTs Create Value

Electrostatic dissipation (ESD) — electronics housings, trays, conveyor components and packaging where static discharge damages sensitive parts

Electrical conductivity — antistatic coatings, EMI shielding materials and conductive components where metal filling is undesirable

Mechanical reinforcement — modest gains in modulus and, more usefully, improved fracture toughness in brittle matrices

Thermal conductivity — heat-spreading in electronics housings and thermal interface materials

Product Forms

Form	What it is	Typical use
CNT powder	Multi-wall or single-wall nanotubes, dry powder	Masterbatch compounding, laboratory and specialty applications
CNT masterbatch	CNTs dispersed in a carrier polymer at controlled loading	Direct compounding into thermoplastics; easier handling than powder
CNT dispersion / slurry	CNTs pre-dispersed in resin or solvent	Coatings, adhesives, in-mold applications

Loading and Dispersion — the Actual Difficulty

Carbon nanotubes are hard to use for one reason: they bundle. Agglomerates never disperse properly, and they act as stress concentrators that reduce strength instead of improving it. Successful use comes down to three things — a consistent grade, adequate dispersion energy, and a loading chosen for the mechanism you need rather than the highest number possible.

• Match the loading to the target: typical antistatic targets are far lower than typical reinforcement targets
• Assess dispersion by microscopy, not by appearance — a visually uniform compound can still contain agglomerates
• Run a small trial first and measure the property you actually need, not just tensile strength

How to Specify

Tell us the target property (surface resistivity, conductivity, toughness improvement), the base polymer and the processing temperature, and we will recommend the form and loading range to trial. We supply CNT powder and dispersions; masterbatch compounding can be discussed against your resin system.
