Envirofoam Sustain

IFS Chemicals of Norfolk, UK have recently introduced a unique product to the polyurethane chemical industry.

The Envirofoam Sustain range of formulated polyols are derived from recycled vegetable oils and are suitable for use in the building, refrigeration, marine and water-storage industries. Having already served their primary industrial purpose within the food processing industry, vegetable oils are collected, recycled and converted to rigid foam polyols. For example, Enviropol R201 has been independently analysed and found to have a biobased content of 86%. This product is used to produce a fully formulated polyol component with 45-60% biobased content and is currently being supplied to manufacturers of coldroom panels, commercial refrigerators, hot water storage appliances, Structural Insulated Panels and supermarket display cabinets.

This unique development is significant in that the starting material is not only renewable but is recycled as well. It has recently gained acceptance to the American “BioPreffered Program”, an initiative aimed at “promoting products that may be more benign to the environment”. The insulation products manufactured with this technology not only help the environment but also exhibit excellent processing and material properties. These include very low lambda values, excellent adhesive properties and the ability to use blowing agents with a global warming potential of “less than 1”.
