SperseStab™ 1245

1 of 26 products in this brand
SperseStab™ 1245 is a slightly less hindered phenol antioxidant that provides increased activity compared to other hindered phenols. It provides excellent processing and long-term stability and has excellent color and solubility in engineering resins, including POM, PA, polyester, and polyurethanes. It can be used in combination with other antioxidants, UV stabilizers, and UV absorbers. Of particular note are combinations with SperseStab™ 1680 as well as combinations with HALS.

Functions: Antioxidant

Compatible Polymers & Resins: Acrylonitrile Butadiene Styrene (ABS), High-Impact Polystyrene (HIPS), Polyamides, Polyethylene Terephthalate (PET), Polyoxymethylene (POM), Polyurethanes (PU), Polyvinyl Chloride (PVC), Styrene Butadiene Styrene (SBS)

Features: Excellent Compatibility, Good Stability, Low Color Formation
