Electro- conductive extruded yarn

Electroconductive extruded yarn

An innovative product with extraordinary features and capabilities was developed from the joining of two great experiences.

LATI and GIMAC have collaborated to evaluate the possible conversion of special compounds manufactured by the former using micro-extrusion technology on machines built by the latter.

Different materials and thicknesses were extruded during several experimental tests. The definitely most interesting product is an electrically conductive yarn obtained by the drawing of a carbon nanotubes (CNT) reinforced PA12 compound.

The yarn obtained features a thickness of less than two-tenths of a millimeter, and offers very interesting properties related to the product formulation and the special extrusion technique. First, the electrical conductivity: carbon nanotubes, evenly dispersed in the matrix, allow the provision of uniform electrical properties on the yarn.

A resistance of about 8 kΩ is measured per centimeter of yarn, but it is possible to change this performance by operating on the CNT content as well as on the conversion parameters.

The electroconductive yarn is not fragile, but remains perfectly flexible, even when bent with strong curvatures, due to the absence of CNT agglomerates that may give rise to discontinuity in the polymer matrix. Excellent yarn deformation is combined with an interesting tensile strength and optimal mechanical properties.

The most interesting aspect is of course the electrical conductivity, a feature that allows a number of possible uses of this product, from electronics to automotive, medical, and mechatronics industry.

LATI's and GIMAC's engineers are at disposal to investigate the opportunities offered by materials, technologies, and companies operating in these fields.
