Solvay and Mitsubishi co-operate on high temperature bio-nylon
Solvay Advanced Polymers and Mitsubishi Gas Chemical Co are to collaborate on the development of a series of renewably-sourced high temperature speciality polymers using a new monomer from Mitsubishi. The work is initially focused on bio-based polyamides which will have a heat deflection temperature of approximately 270 degC for glass-filled compounds. At this level the companies say the new polymer will have greater thermal performance than many current bio-based polyamides and polyesters.
These polyamides, based on sebacic acid derived from castor oil, are expected to be among the highest temperature bio-based polyamides in the industry and will complement Solvay's high-temperature Amodel polyphthalamide. Among the properties of the new material will be low moisture retention, and a high crystallisation rate, wear resistance, and toughness. Key potential uses include reflow soldering applications, high-temperature automotive parts, and sliding applications such as gears.
Solvay and MGC are currently working on an optimised manufacturing process for the new polymer. Meanwhile, MGC has filed patents covering its development work in material composition, production, and applications.
The two companies have a long-standing history of co-operation, with MGC having supplied Solvay for 25 years with MXDA monomer for the production of Ixef polyarylamide.
