TCI C2158 is a multi-walled carbon nanotube material with a tube diameter of 60–100 nm and a length exceeding 5 micrometres. Structurally, it consists of hollow tubes formed from graphene walls stacked in a relatively high number of layers, which produces a thicker and stiffer tube than small-diameter variants. In the laboratory, this material is used as a structural reinforcement in composites, as an electrical and thermal conduction pathway within polymer or cement matrices, and as a study material in research examining the relationship between nanotube dimensions and the performance of the final material.
The defining characteristics of this variant are its thick walls and long tubes. A diameter of 60–100 nm gives the tube a higher flexural rigidity, so it does not bend or curl easily when mixed into a viscous matrix, and the transfer of mechanical load proceeds more effectively. A length above 5 micrometres maintains a high aspect ratio, so a conductive network still forms readily throughout the host material. Powder with a larger diameter also tends to be less fine than thin-walled variants, which makes handling and weighing at the bench feel more manageable, while the large number of walls contributes structural stability to the individual tubes.
In Indonesian laboratories, this grade is typically drawn on by materials science and engineering groups working on composite formulation, by teams developing conductive polymer or cement-based systems, and by academic researchers studying how nanotube geometry governs the properties of a finished material. It suits work at the formulation and characterisation stage, where a stiffer, longer nanotube is preferred over finer grades, and where the comparative behaviour of different tube dimensions is itself the subject under investigation.
- Composite reinforcement: the thick walls and high flexural rigidity allow the tubes to resist bending during mixing and transfer mechanical load through the host matrix effectively.
- Conductive polymer systems: a length above 5 micrometres preserves a high aspect ratio, so a continuous conductive network forms readily at practical loadings within the polymer.
- Cement-matrix research: the stiff, large-diameter tubes survive incorporation into a viscous cementitious matrix without curling, supporting both electrical and thermal conduction studies.
- Thermal conduction studies: the stacked graphene walls provide a pathway for heat transfer through polymer or cement matrices where a conductive filler network is required.
- Dimension–performance research: this variant serves as a defined 60–100 nm reference point for studies correlating nanotube diameter and length with final material performance.

- Product designation: C2158, Carbon Nanotube Multi-walled, 60–100 nm diameter, >5 µm length
Store the material in its tightly closed original container, in a dry, well-ventilated area away from direct sunlight and sources of ignition. Containers should seal securely to prevent moisture ingress and to keep the fine powder contained during storage and transport. Because this is a nanoscale powder, weighing and transfer are best carried out in a fume hood or a suitable containment enclosure to limit airborne dispersion. Wear gloves, safety glasses, and a laboratory coat, and use appropriate respiratory protection where dust may be generated. Clean spills by wet methods or vacuum rather than dry sweeping, avoid raising dust, and wash hands after handling. Consult the manufacturer's safety data sheet before use.
