Chevron Phillips Oxygen-Scavenging Polymer OSP100M Catalyst & Photoinitiator Masterbatch
Subcategory: Thermoplastic
Material Notes: Cobalt content 1.0 % (wt.). Photoinitiator content 1.0% (wt.). Primary antioxidant 600 ppm. OSP100M is a general purpose catalyst/photoinitiator masterbatch. This resin should be blended with one of the EMCM resins in order to properly activate the oxygen scavenging mechanism. Typical blend ratios range from 95:5 to 85:15 (EMCM/MB) with 90:10 being the recommended blend ratio for most applications. Recommended extrusion melt temperatures range from 250°F to 400°F. OSP polymers are used in packaging for O2-sensitive applications from food to electronics. Packaging produced with OSP polymers can extend product life, eliminating waste and providing greater distribution flexibility. Oxygen scavenging rates and capacities are influenced significantly by UV activation dose, use conditions such as storage temperatures, and initial package oxygen content.
