Premi-Glas® 2206-15 CR-SX is a fiberglass reinforced thermoset sheet molding compound for electrical, flame retardant, and HVAC applications. Key Features and Benefits: Non-Halogen FR technology for regulatory compliance. Pigmentable for molded-in color; best appearance with mold texture. UL 94-5VA flame resistance at 2.3mm minimum thickness. Suitable for outdoor use in applications involving UV exposure and water immersion in accordance with UL746C (f1). File E42524. This SMC product is generally intended to be compression molded in matched metal die molds, typically at 300°F (150°C) and 500 to 1000 psi (35-65 BAR) molding pressure. Strength values may be affected by the molding process. Nominal values for polymerization shrinkage (0.0015 to 0.0025 in/in) and specific gravity (1.75 to 1.85) may be customized for individual applications. Contact your A. Schulman sales representative for specific design recommendations.&& |
