AOC Leads Composites Into the “Green” Revolution With EcoTek

Launched at Composites 2010, AOC’s EcoTek Green Technologies aim to help customers become better environmental stewards, follow green regulatory standards, and meet the growing demand for manufactured goods that are friendlier to the environment.

The EcoTek line debuts with a line of unsaturated polyesters and vinyl esters, which AOC say often offer processing and end-use properties that are better than or equivalent to conventional materials.

“AOC pioneered green resin technology in the 1980s when the company introduced unsaturated polyesters which chemically incorporate recycled polyethylene terephthalate, or PET,” said Emilio Oramas, Business Manager – Open Mold Reinforced. “Over the years, we expanded development of Earth-friendly materials that support customer preferences and requirements for greener practices. Our work has grown to the point where we can launch our new class of EcoTek materials.”
EcoTek product technologies follow three major paths toward greenness. Many products follow more than one these paths:

1. Renewable Content
AOC can offer several resin options that use building blocks derived from renewable resources instead of fossil fuels. The renewable content comes from agricultural products such as corn, plant oils and/or other sustainable resources that are precursors to the building blocks of the polymeric backbone. Resins made with these building blocks provide green alternatives to resins produced from building blocks that are wholly derived from crude oil and natural gas.

2. Recycled Content
EcoTek recycled content comes from reclaimed polyethylene terephthalate (PET) that would otherwise be destined for a landfill and/or from reclaimed glycols that would require diversion into a chemical waste stream.

3. Styrene Free
AOC has patented a new resin technology that is free of styrene. New resin formulations incorporate alternative reactive diluent monomers that have very low volatility for reduced exposure in the workplace and lower emissions in the environment.
