  • New kind of lactide caprolactone copolymer developed
  • Renewable content exceeding 80%, fully compostable
  • Alternative to EVA and mPE
  • Application: hot melt adhesives

Resulting from a partnership agreement signed in 2011, Perstorp and Corbion jointly launched a new lactide caprolactone copolymer for hot melt adhesive applications. The two companies are market leaders in their respective fields of caprolactones (Perstorp) and lactides (Corbion). The new material is part of Perstorp’s Capa Lactide and expected to be the first in a series of new developments for the adhesive industry.

Renewable content exceeding 80%, fully compostable

The new product has a renewable content exceeding 80% and is fully compostable, providing adhesives manufacturers with a new alternative to improve food safety aspects of packaging and at the same time meet the growing demand for more sustainable products. Equally importantly, the new material delivers no compromise on performance and allows formulators to remain competitive.

Alternative to EVA (ethylene vinyl acetate) and mPE (metallocene-catalyzed polyethylene)

Corbion’s Senior Vice President Biochemicals, Marco Bootz, 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 that provide a genuine alternative to traditional materials like EVA (ethylene vinyl acetate) and mPE
(metallocene-catalyzed polyethylene) for the adhesive industry.”

The new product is expected to be commercially available in the final quarter of this year and will be brought to market by Corbion.
