BODA RESINS
Bis-ortho-diynylarene (BODA)-derived resins (BDR) are our premier product currently being introduced to the market. This platform of resin materials offers melt or solution processing compatible with numerous existing fabrication methods for composite and micro/nano structures. They form high temperature thermosets that thermally convert into graphitic carbon with extreme efficiency and fidelity. These properties make them disruptive carbon precursors as they have the potential to significantly increase the cost-efficiency of manufacturing various high value carbon components.
Processable and High Carbon Yielding.
The base unformulated BDR can be synthesized via a scalable process from commodity feedstocks and can be thermally processed as high melting point (>100 °C), low melt-viscosity (100-300 cP at 200 °C) monomers/oligomers with high melt stability (3 h before vitrification). Polymerization is volatile-free, non-autocatalytic, and thermally-initiated at 240-250 °C to give polycyclic-arylene oligomers and networks which convert to carbon in yields (>80%). The resulting thermosets have a high thermal-oxidative stability (~5 wt% loss after 12 h at 300-400 °C), low fire growth capacity (12-32 J/g-K) and high carbon yields (75-85%) at 1000 °C.
OUR BODA CAN BE OBTAINED OR PROCESSED IN DIFFERENT FORMS
Powder
Monomer is a yellow powder with a high-melting point (180 °C), and a long shelf-life (>5 years).
B-Staged
Can be provided as a low- and high- melt viscosity resin.
Solution
Both the monomer and B-staged BODA resins are soluble in various organic solvents.
POLYMER & CARBON MATRIX COMPOSITES
Process the BODA, cure it, and/or carbonize it to obtain excellent results at C-0. This approach to making high-temperature polymer and carbon structures is facile and amenable to different fabrication methods. Contact us today to learn more.
