Premi-Glas® 3406 is a fiberglass reinforced thermoset sheet molding compound for mass transit third rail insulators and other semi-structural applications where low smoke and low flammability are required.

Radiant panel flame spread index of less than 20 per ASTM E-162.

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

Excellent flexural strength and outstanding toughness.

Halogen-free flame retardant system for reduced smoke toxicity.

Material properties conform to requirements of NYCTA 60-MTA.
