LyondellBasell Montell 8340 Polybutene-1 (discontinued **)
Categories:	Polymer; Thermoplastic; Polybutene
Material Notes:	Key Features: semi-crystalline low ethylene content random copolymer, miscible with polypropylenes, FDA acceptable Applications: minor additive in a polyethylene peel seal layer Meets FDA requirements in 21 CFR 177.1570 for direct food contact up to 212°F (100°C). Description: Polybutene-1 PB 8340 is a semi-crystalline low ethylene content random copolymer which is miscible with polypropylenes due to its similar molecular structure. In blends with polyethylenes it is immiscible but easily dispersible. This copolymer is used in the packaging industry primarily as a minor additive in a polyethylene seal-peel layer for the production of coextruded flexible film or more rigid sheet. Varying the concentration in the seal-peel layer offers the unique possibility of tailoring the seal strength for controlled easy-opening of peelable seal packaging. This grade is particularly suitable for use in blown film formulations when low heat seal initiation temperatures are required. A typical blend partner is a high density polyethylene with a melt index range between 2 and 8 dg/min. This copolymer meets FDA requirements for direct food contact under regulation 21 CFR 177.1570. Information provided by Montell Polyolefins. LyondellBasell is the successor company to Montell.
