o The projection trend of Global Automotive GF/PBT Market increasing every yearfrom 2013 to 2024 (including long fiber, short fiber/PBT) [7].
o Some of the application of PBT in automotive include Roof Panel, Body Panels, Chassis and others [7].
Key Characteristics
• High mechanical strength,
• Good dimensional stability,
• Rapid crystallization rate (desirable for injection molded part) and
• High heat deflection temperature.

• At only small amount of the corn oil/PBT and corn oil/PTT blends showed significant flame retardancy.
• The fire class of PBT changed from non-rating (NR) burning fire class to not burning fire class (V-2).
• The time to stop the propagation of fire was reduced significantly after incorporation of modified corn-oil in PTT.
Fire Test UL-94:Vertical Burning Test
Conclusions1. Downstream corn oils from bioethanol industry was successfully
modified and utilized as a sustainable feedstocks for the synthesis of biobased flame retardant for engineering plastics.
2. The flame retardancy of the engineering plastics i.e. poly(butylene terephthalate) and poly(trimethylene terephthalate) were improved significantly after incorporation of our synthesized functionalized biobased flame retardant from downstream corn oil.
3. Unlike conventional flame retardant, the incorporation of small amount (<10 wt%) of these biobased flame retardant changing the UL-94 fire class of PBT from non-rating (NR) burning class to not burning fire class (V-2).
