Perstorp and Purac to develop caprolactone lactide co-polymers

Speciality chemicals company Perstorp and biobased chemical maker Purac are partnering to develop caprolactone lactide co-polymers for the plastic, coatings and adhesive markets, utilising complementary strengths of Perstorp in speciality products for coatings and plastics with Purac in renewable lactic acid based chemicals.

Perstorp says it is expanding its Capa range with a partly renewable product. Possible uses for this new caprolactone lactide co-polymer are, amongst others, as polyols for CASE (coatings, adhesives, sealants and elastomers) and for biodegradable plastics and hot-melt adhesives. Its unique composition makes it possible to control both the melting point and mechanical properties in particular thermoplastics, further reducing the crystallinity of polyols. The new caprolactone lactide co-polymer will be launched to the market by Perstorp during 2013 and presented at the K-fair in October. Trial orders have already been delivered with positive results.
