Brightner OB-1 Greenish Powder for PVC for Styrenic and Acrylic Polymers Cas No.1533-45-5
Product Features:
Recommended loading concentrations for OB-1 range between 50 and 1000 ppm(0.005-0.1%). The product can be used alone or in a variety of blends and combinations with other additives, including antioxidants, processing stabilizers, and light stabilizers. Higher load levels of Syntex OB-1 are required if it is used in combination with a UV absorber. The exact formulation to be used is dependent on the substrate, performance requirements, and other factors, and should be determined by the user based on testing to simulate actual conditions of use. Due to the high melting point of the product (359℃), care must be taken to ensure complete dispersion when Syntex OB-1 is used in polymers processed at lower temperatures such as styrenics and acrylics.
