PPG Industries (Pittsburgh, Pa.) has expanded its portfolio of glass products with the addition of three CHOPVANTAGE chopped strand fiber products. CHOPVANTAGE HP3270 fiber glass is a 10-micron chopped strand fiber that offers high performance in polypropylene compounds and improved chemistry for DAM (dry as molded) properties. PPG says it provides good performance in standard application compounds as well as hot detergent solutions. Applications include automotive and appliances. CHOPVANTAGE HP3613 chopped strand reinforcement offers the proprietary sizing chemistry of the CHOPVANTAGE HP3610 chopped strand fiber glass in a 13-micron fiber diameter. Available for polyamide applications, it offers high hydrolysis resistance in long-life coolant systems and meets U.S. Food and Drug Administration and EU food compliance requirements as well as potable water guidelines. CHOPVANTAGE HP3730 chopped strand fiber glass offers good DAM properties and hydrolysis resistance in thermoplastic polyesters, such as PBT (polybutylene terephthalate) and PET (polyethylene terephthalate). In addition, it delivers good mechanical properties in biodegradable plastics such as PLAs (polylactic acids), PHAs (polyhydroxyalkanoates) and PTTs (polytrimethyleneterephthalates). Applications include transportation, electric and electronic appliances and computer housings and components.
