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

Modification of existing resins with biobased PURALACT® lactide adds value to any production chain

Purac, a leading player in natural food preservation and biobased building blocks & chemicals, and Perstorp, a leading specialty chemicals company today announced a research and business development partnership for caprolactone lactide co-product, for amongst others coatings and adhesive markets.

Combining the complementary strengths of Purac in renewable lactic acid based chemicals and Perstorp in specialty 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 unique composition makes it possible to control both the melting point and mechanical properties and reduce the crystallinity of polyols.

“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 specialty 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 CapaTM range with partly renewable products,” says Market Development Director, Håkan Björnberg.

The new caprolactone lactide co-products will be launched to the market by Perstorp during 2013 and presented both at K-fair and at the European Coatings Show. A number of lead customers have already been supplied with the new co-resins and have approved these in their final products.
