Liquid colour concentrates based on sustainable natural raw materials

PolyOne has introduced a new range of liquid concentrates based on sustainable natural raw materials to be used in bioplastics for biodegradable applications.

It is compatible with bioderived polymeric resins and compliant to European food contactregulations.

It can be used in various bio­polymers like PLA or starch based blends. Testing has shown no significant migration even after a long ageing period, says PolyOne. The viscosity range of the new colorants allows the use of standard dosingequipment.

PolyOne has already developed a range of additives and colour concentrates in solid form for use in biopolymers. The new liquid concentration will complete the existing OnColor Bioportfolio.
