With new EU regulations regarding primary aromatic amines (PAAs), ColorMatrix AAnchor offers reduced regulatory risk as it will not form PAAs, unlike other ATA-based solutions. It is compatible with PET bottles formed from an extrusion blow-molded or stretch blow-molded process.

It works by bringing incompatible polymers – such as PP and PE – together by forming them into a homogenous polymer mixture that increases mechanical properties based on polymer modification.

THERMOPLASTIC The matrix material of a composite can be a thermoset or a thermoplastic THERMOSET THERMOPLASTIC A thermoset is a cross-linked polymer that cannot be reshaped after it’s formed, cured, and cooled.

It takes various forms, such as slavery, servitude, forced and compulsory labour and human trafficking, all of which have in common the deprivation of a person's liberty by another in order to exploit them for personal or commercial gain. Avient forbids any form of forced labor or human trafficking in connection with Avient’s business and we expect our suppliers, agents, and distributors to prohibit the same.
