LyondellBasell Astryn CA743GA Polypropylene Copolymer (discontinued **)
Categories:	Polymer; Thermoplastic; Polypropylene (PP)
Material Notes:	Key Features: low melt flow, low modulus, UV-stabilized polypropylene copolymer with antiblock, good heat seamability, good puncture resistance, plasticizer-free, excellent low temperature impact resistance, excellent chemical and environmental stress-cracking resistance, pelletize resin Applications: geomembranes, sheet All ingredients meet TSCA (US) and DSL (Canada) registration requirements. Description: Astryn CA74GA low melt flow, UV-stabilized, flexible polypropylene copolymer with antiblock is designed for geomembranes. It is based on proprietary Montell process technology and sheet made from it can be blown, slot die-extruded or calendared, with or without scrim, into a final form. This UV-stabilized, pelletized resin, when blended with an N-110 carbon black polyolefin carrier masterbatch to a concentration of 2.75% by weight carbon black in the finished product, provides exceptional weatherability. All ingredients meet the chemical registration requirements of TSCA and DSL. Information provided by Montell Polyolefins. LyondellBasell is the successor company to Montell.
