Pinnacle™ PP 4208

8 MELT FLOW HIGH IMPACT COPOLYMER FOR INJECTION MOLDING Pinnacle Polymers Polypropylene 4208 is made via UNIPOL™ PP technology, which utilizes gas-phase fluidized bed reactors with a high activity catalyst system to ensure uniform physical properties and lot-to-lot consistency.This product is intended for general extrusion or injection molding applications. Also contains a long term heat aging additive system. Has superior high and low temperature impact.The 4208 product provides: Wet/Dry environment resistance Superior balance of stiffness and impact strength Excellent long term heat aging properties Excellent color and processing stability Enhanced weld-line strength Pinnacle's 4208 polypropylene is covered under US FDA Food Contact Notification 864. As such, this polymer can be used in contact with all food types under Conditions of Use A-H, as described in 21 CFR 176.170, Tables 1 and 2. This polymer also complies with 21 CFR 177.1520(c), items 3.1(a) and 3.2(a).
