Purac and Perstorp in partnership to develop caprolactone lactide co-product

According to the partners, combining the complementary strengths of Purac in renewable lactic acid based chemicals and Perstorp in speciality products for coatings and plastics has already resulted in partly renewable caprolactone lactide co-products. Possible uses for these new caprolactone lactide co-products are, amongst others, as polyols for coatings, adhesives, sealants and elastomers and as hot-melt adhesives. Its composition makes it possible to control both the melting point and mechanical properties and reduce the crystallinity of polyols.

The new caprolactone lactide co-products will be launched to the market by Perstorp during 2013. A number of lead customers have already been supplied with the new co-resins and have approved these in their final products, says the company.

“We look forward to our cooperation with Perstorp. Our first jointly developed caprolactone lactide co-products show that the modification of existing resins with biobased Puralact lactide adds value to the value chain by combining increased sustainability with enhanced performance”, according to Vice President Chemical & Pharma, Marco Bootz.

“We are very excited about this strategic partnership with Purac, which has a strong position in bio-based products for a broad range of industries. With Perstorp’s strong position in speciality products for coatings and plastics, our respective skills and experience comprise a good foundation for a successful research and business development and means that we are expanding our Capa range with partly renewable products,” said Market Development Director, Håkan Björnberg.
