A. Schulman Premi-Glas® 1200-22 Fiberglass Reinforced Thermoset SMC
Categories: Polymer; Thermoset; Composite SMC; Filled/Reinforced Thermoset

Material Notes: Premi-Glas® 1200-22 is a fiberglass reinforced thermoset sheet molding compound for general purpose applications requiring thermal stability and stiffness.

Key features and benefits are:

  • Excellent stiffness to weight ratio, non-melting
  • Good dimensional stability, including excellent thermal resistance
  • Pigmentable for molded-in color; best appearance with mold texture
  • Excellent property retention in cold and hot environments
  • Good corrosion resistance except in acid environments.
  • Designed for compression molding in matched metal die molds.

A. Schulman has acquired this former Premix product line.
