Proprietary Polyamide Resin

developed from unique C9 monomer

Genestar™ is a registered trademark for the innovative and proprietary polyamide resin (PA9T) developed from unique C9 monomer, manufactured and marketed by Kuraray. 

Key features of Genestar™:  

High Heat Resistance

Genestar™ has a high melting temperature of 306 °C and a high glass transition temperature of 125°C

Low Moisture Absorption

Genestar™ has one of the lowest moisture absorption in the high temperature polyamide family

Good Molding Ability

Genestar™ is thermally and dimensionally stable, and can be molded easily 

High Mechanical Properties

Genestar™ possess good weld strength, toughness and abrasion properties and can be added with fillers to enhance its performance further 

Electrical Properties

Genestar™ is rated Class 0 (PLC) for tracking resistance and has RTI (electrical) of 150°C

Chemical Resistance

Genestar™ possess better chemical resistance compared to the other high temperature polyamide 


In comparison with other polyamides, Genestar™ PA9T is a well-balanced polymer that can improve the performance of your products.  

Genestar™ PA9T is commonly used in SMT applications due to its good blister resistance, good dimensional stability and low moisture absorption.
It is often used in electronics applications for switches, camera module housing and various types of connectors such as USB, DDR, board-to-board, wire-to-board and FPC. It is also widely used in LED application for lighting of smart phone, tablet, notebook, LED TV and lighting. It is also gaining market share in automotive industry for metal replacement due to its excellent chemical resistance, high crystallinity and high heat resistance, and replacement of other polymers due to its good mechanical properties, high heat resistance and ease of processing.
