High quality secondary antioxidants for a broad range of polymers.
Galata’s Markphos® phosphite stabilizers are typically used in PVC formulations in combination with mixed metal stabilizers. These organic phosphites are useful in protecting properties of many polymers and perform a variety of functions, including maintaining transparency and initial color hold. Organic phosphites are also effective in reinforcing the effectiveness of primary antioxidants as thermal stabilizers & processing aids in polyolefins, elastomers, and engineering thermoplastics, and upgrading the service life and weatherability of plastics in outdoor applications.
Our phosphite co-stabilizers are also added to polyolefins, polyurethane, and other polymer resins. Through Galata’s strong global manufacturing, sales, and technical service footprint, we have been a reliable partner to our customers for addressing their stabilizer needs.
