Unitaka, a Osaka, Japan-based plastics company, recently released its XecoT series of thermally-conductive polyamide resins that are targeted to thermal management applications for LED, electric vehicles, and other electronics sectors, according to a report from Plastics Today.

The Unitaka Plastics Division website explained, “XecoT is an aromatic polyamide resin which has overwhelming performance based on Unitika's original polymerization and compound technology. High crystallinity has been achieved by creating homo structure described above. High heat resistance, low moisture absorption, great sliding performance, which have been derived from its high crystallinity. XecoT are made by the biomass material.”
XecoT has a high melting point, well over 300°C according to a chart on the Unitaka site, as well as reflow heat resistance and retains its mechanical properties at high temperatures. It also has lower water absorption than other nylons and has an option for high-lubrication grade material.
Plastics Today reported, “Each conductive grade incorporates a filler that neither unduly increases the compound density versus insulating grades, nor compromises mechanical properties. Injection molding processability also is said to be outstanding. For example, a thermally-conductive PA 6 grade, N1010RG, exhibits a bar flow length of 235 mm at 280°C and 150 MPa (1-mm thick test pieces). Unitika has split its offerings into electrically insulative and conductive types that exhibit varying degrees of thermal conductivity.”
