For professionals in materials science, manufacturing, and R&D, understanding the precise specifications of Multi-Walled Carbon Nanotubes (MWCNTs) is critical for successful application development. At NINGBO INNO PHARMCHEM CO.,LTD., we recognize that the performance of MWCNTs is highly dependent on parameters such as purity, diameter, and length. As a leading supplier, we are committed to providing clarity on these specifications to help our clients make informed purchasing decisions.

Purity is a fundamental attribute of MWCNTs, often expressed as a percentage of carbon nanotubes relative to other carbonaceous materials or residual catalysts. High-purity MWCNTs (e.g., >95% or >99%) are essential for applications demanding consistent electrical, thermal, or mechanical properties, such as advanced electronics and high-performance composites. Conversely, lower-purity grades might be suitable for less sensitive applications or where cost is a primary driver. When you aim to buy high purity carbon nanotubes, it's important to consult detailed Certificates of Analysis (COA) from your supplier.

The diameter of MWCNTs significantly influences their properties. Outer diameters typically range from a few nanometers to over 100 nanometers. Smaller diameter MWCNTs generally exhibit higher aspect ratios and can offer superior mechanical reinforcement and electrical conductivity. Conversely, larger diameter MWCNTs might be preferred for certain dispersion characteristics or specific applications. As a trusted MWCNT supplier in China, we offer a range of diameters to suit diverse needs.

Length is another crucial factor, affecting the entanglement, percolation threshold, and overall reinforcement efficiency of MWCNTs in composite materials. Typical lengths can range from a few micrometers to several hundred micrometers. Longer MWCNTs tend to form more robust networks, leading to greater improvements in mechanical properties. When you consider the carbon nanotubes price, the specified length and purity are key determinants. NINGBO INNO PHARMCHEM CO.,LTD. provides detailed specifications for all our MWCNTs, ensuring you can purchase the exact materials required for your innovation.
