*Use to replace the formulation of B215 plus DSTDP/DLTDP or 412S LTF631 possesses much longer protection of plastic materials in anti-thermal aging compared to LTF641, in addition LTF631 showed better anti-yellowing property than LTF641.

Applications

ACANOX LTF631 is a formulation of three components with both processing and long-effective high temperature antioxidants, pH is neutral. It exhibited excellent antioxidant properties, and stabilities in acidic, basic, and other contaminated environment, therefore LTF631 provides outstanding protections to polymer materials. It is well compatible with PP, PE, ABS, PVC as a long-acting antioxidant, as well as TPO, TPE, TPV, PS, PU, PA and their alloy materials. LTF631 also has shown much stronger protection to natural color, light color with excellent anti-yellowing properties. It has also excellent matching with other polymer additives, such as weak alkali, weak acidic and neutral additives. It has shown very good performance records in different polymers and it presented low odor and low VOCs during processing and services terms.
