Flexible Heat Resistant Polyamide

Research & Development

Soft Super Engineering Plastics

Flexible Heat Resistant
Polyamide

New resin material with both flexibility and heat resistance at a high level.

Unitika's unique polymerization and morphology control technologies have made the heat-resistant polyamide XecoT™ flexible. While maintaining the characteristics of XecoT™ such as heat resistance, chemical resistance, and biomass-derived, it has achieved a low elastic modulus comparable to that of rubbers and elastomers. This material set a new concept of "SOFT SUPER ENGINEERING PLASTIC". We aim to apply this technology to flexible materials such as tubes, sealants, anti-vibration materials, and wearable devices.
