Material Notes:
Premi-Glas® 1200H-20 is a 20% fiberglass reinforced, thermoset, Sheet Molding Compound designed for applications where good arc resistance and dielectric strength are required and UL 94HB flame recognition properties is sufficient. Key features and benefits are:Underwriters Laboratory UL 94HB flame recognition at 1.47mm minimum wall thickness. U.L flame recognized in all colors. Excellent flexural strength and flexural modulus properties. Designed for compression molding in matched metal molds. Available in fiberglass content of 10-30%. The Premi-Glas 1200-H series carries U.L 746 C recognition for use in exterior applications following ultraviolet light, water emersion and exposure testing.Data provided by Premix.
