Bio-based polymers derived up to 60% from renewable resources

April 13, 2016 // By Julien Happich
Royal DSM has expanded its range of high temperature resistant bio-based polymers with the introduction of a new family of high performance polyamide 4T materials, partially produced from renewable resources, called ForTii Eco.

The polymer in the new grades is 30% to 60% derived from renewable resources. DSM uses castor beans as the basis for the C10 chemistry that it incorporates. The grades have a bio-content ranging from 10% to 25% by weight on a compound basis.

The first three grades in the family are ForTii Eco E11, ForTii Eco E61 and ForTii Eco LDS62, providing halogen-free solutions for parts with thinner walls, with excellent mechanical and dielectrical properties. The ForTii Eco E11 and ForTii Eco E61 are aimed at surface-mount connectors, like the new USB-C, and also audio jacks, while the ForTii Eco LDS62 is well suited for antennas, RFID security casings, and switches. All three bio-polymers show low sensitivity to moisture, which ensures that their mechanical and dielectrical properties are retained even in the conditioned state. These new grades also offer higher flow and an improved processing window, combined with high toughness and full resistance to high temperature soldering.
