Premi-Glas® 3404 is a fiberglass reinforced thermoset sheet molding compound for mass transit and semi-structural applications where low smoke and low flammability are required.

Key Features and Benefits:

Radiant panel flame spread index of less than 35 per ASTM E-162.

Smoke Density of less than 25 per ASTM E662 (NBS smoke chamber).

Accepts powder in-mold-coatings.

Excellent flexural strength and outstanding toughness.

Halogen-free flame retardant system for reduced smoke toxicity.
