Biopolymer research is able to replace petroleum-based plasticezers. In partnership with Phifer, Chilewich has developed TerraStrand. The new fabric is composed of renewable, vegetable-based compounds, for a phthalate-free product that’s not only safer and more sustainable than traditional vinyl, but just as durable and equally easy to clean. The 2013 introduction at NeoCon marks the company’s commitment to replacing all of its yarns with TerraStrand product.
