TYRIL™ 790

About
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 processabiltiy. 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, toothbrshes Electronics: dust covers, display screens Complies with: U.S. FDA 21 CFR 181.32 European Food-Contact Compliance&&
