Trinseo TYRIL™ 790 Styrene-Acrylonitrile
Categories:	Polymer; Thermoplastic; SAN Polymer
Material Notes:	TYRIL™ styrene-acrylonitrile (SAN) resins are designed to offer superior chemical resistance, strength, hardness and dimensional stability in a broad range of product applications. The key property of TYRIL 790 is its high flow that results in excellent processability. TYRIL 790 is specifically designed for end-use applications requiring a good balance of physical properties, optical properties (gloss, clarity or opaqueness), heat resistance and practical toughness. Applications: Tableware: airline serviceware, other multi-cavity applications Personal care: combs, toothbrushes Electronics: dust covers, display screens Complies with: Europe Food-Contact Compliance FDA, 21 CFR.177.1640.
