Chevron Phillips Oxygen-Scavenging Polymer OSP101M Catalyst & Photoinitiator Masterbatch

Subcategory: Thermoplastic

Material Notes:
Cobalt content 1.0 % (wt.). Photoinitiator content 0% (wt.). Primary antioxidant 0 ppm.

OSP101M is a cobalt-only catalyst masterbatch for use in molding applications where thermal activation of oxygen scavenging is desired. This resin should be blended with OSP503R, EMCM resin, 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 450°F to 550°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.
