Title: Hiroshi Ieki: Innovator in Polyamide Film Technology
Introduction
Hiroshi Ieki is a notable inventor based in Inuyama, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced polyamide films. His innovative work has implications for various applications, especially in packaging materials.
Latest Patents
Hiroshi Ieki holds a patent for a unique meta-xylylene diamine/aliphatic dicarboxylic acid polyamide film. This drawn film exhibits an oxygen permeability coefficient of not more than 5 × 10-13 ml.cm/cm2.sec.cmHg. It also boasts a breaking strength of not less than 14 kg/mm2 and a breaking elongation of 30 to 150%. The film can be manufactured by drawing an undrawn polyamide film biaxially at a specific temperature and optionally heat treating the resulting drawn film. The undrawn polyamide film is made from a polyamide with a relative viscosity of about 2.0 to 4.0, which contains at least 70% (mol) of the repeating unit constituted with meta-xylylenediamine or its mixture with para-xylylenediamine and an α,ω-aliphatic dicarboxylic acid having 6 to 10 carbon atoms. This film is particularly useful as a packaging material due to its excellent properties in tensile strength, yield strength, Young's modulus, heat stability, size stability, transparency, and gas barrier property.
