Trinseo STYRON A-TECH™ 1175 Polystyrene Resin
Categories:	Polymer; Thermoplastic; Polystyrene (PS)
Material Notes:	STYRON A-TECH™ 1175 advanced technology polystyrene is a high impact, environmental stress crack resistant (ESCR) resin, designed for extrusion and thermoforming applications, especially for the refrigeration industry. Based on patented technology, this resin allows for potential downgauging and scrap reduction in the thermoforming process through its combination of properties like ESCR, rigidity and thermoforming. Main Characteristics: Allows for downgauging ESCR to food stuff and hydrocarbons Ease of processing in extrusion and thermoforming Excellent thermoforming behavior Increased rigidity Applications: Large Appliance/Refrigeration liners General extrusion/thermoforming applications requiring ESCR Complies with: Europe REGULATION (EC) 10/2011 FDA, 21 CFR.177.1640 Consult the regulations for complete details Information provided by Trinseo.
