OCSiAl has introduced a breakthrough solution for latex gloves with electrostatic discharge (ESD) properties that fulfils the conditions prescribed by the new EN 16350:2014 Standard. TUBALL™ LATEX is a new conductive nano additive that delivers an unparalleled level of electrical conductivity, while simultaneously maintaining both the technology process and colour brightness.
New Standard for Anti-static and ESD Gloves - New Solution
Until now there were no products available on the market that fully complied with the new Standard and which required minimal changes to be made to manufacturing process.
OCSiAl has introduced a breakthrough solution for latex gloves with electrostatic discharge (ESD) properties that fulfils the conditions prescribed by the new EN 16350:2014 Standard. TUBALL™ LATEX is a solution for manufacturing latex gloves with anti-static properties.
Single-wall carbon nanotubes (SWCNTs) with a high aspect ratio and large surface area are capable of forming inter-connected networks. This means that a lower loading - starting from 0.03% (mass percentage) per solid rubber of carbon nanotubes is required to provide excellent electrical conductivity whilst simultaneously maintaining the mechanical properties of the elastomeric matrix.
Based on high quality dispersed single-wall carbon nanotubes, TUBALL™ LATEX enables permanent and humidity-independent conductivity levels that are fully compliant with the new European standard EN16350:2014 to be achieved.
• Suspensions for all latex types
• Effective concentration of TUBALL™ 0.05%
• Standard dipping process
• Retains colour
• Electrical resistivity
• Material is ready to use «as produced»
Furthermore, TUBALL™ LATEX, in contrast to the majority of conductive additives, provides significant physical property improvements by reinforcing the latex structure even at extremely low concentrations. After assessing the mechanical properties of medium modulus natural latex (CL60) before and after applying 0.03% of SWCNTs to the matrix, it was found that the tensile parameter M100 increased by 21%, and M300 by 30%. Tensile strength also improved by 19%, while elongation at break remained unchanged.
