Ford Motor Company's biomaterial researchers have engineered a patent-pending formula to use renewable soy oil to improve rubber car parts and make them more environmentally friendly.
By using renewable soy oil as a 25 percent replacement for petroleum oil, Ford researchers more than doubled rubber's stretchability and reduced its environmental impact. Soy-based rubber parts such as radiator deflector shields, air baffles, cupholder inserts and floor mats are under consideration for future Ford vehicle programs.
"Ford is focused on finding innovative ways to make our vehicles more eco-friendly," said Cynthia Flanigan, Ford Technical Leader in Elastomeric Polymers. "Soy-based rubber has win-win potential as it provides superior stretchability and serves as a renewable resource that helps reduce carbon dioxide emissions from raw materials."
The scope of Ford's recent rubber research, which was funded in part by grants from the United Soybean Board (USB), included the use of soy fillers (flour, meal) as well as soy oils. While rubber's role in automotive applications is generally not a glamorous one, it is significant. According to the International Rubber Study Group, the automotive sector accounts for more than 50 percent of worldwide rubber consumption, which exceeded 22 million metric tons in 2008. Automotive rubber usage is expected to rise more than 4 percent through 2013.
