Swedish speciality chemicals firm Perstorp and Dutch biotechnology firm Corbion have jointly developed a new lactide caprolactone copolymer for hot melt adhesives.

The fully compostable copolymer is said to have renewable content of more than 80%, which allows adhesive manufacturers to serve the increasing demand for sustainable products and address food safety concerns in packaging.

The material will offer good performance and allow formulators to remain competitive, the companies said. It is expected to be commercially available during the fourth quarter of 2015.

Marco Bootz, Corbion’s senior vice-president biochemicals said: "This new material represents the culmination of two years' joint development work with Perstorp. It will create a strong technology platform for the development of polymers, which provide a genuine alternative to traditional technologies for the adhesive industry."

The breakthrough innovation for adhesives is part of an agreement signed by the companies in 2011.

Perstorp innovation vice-president Håkan Björnberg said: "Through this partnership, we supply adhesives manufacturers with a competitive advantage by providing safe, innovative technologies that deliver high performance with a reduced environmental footprint."
