MOLDING COMPOUNDS GSP-8, GSP-32, GSP-400

Molding compounds GSP-8, GSP-32, GSP-400 are manufactured of non-twisted glass strands (E-glass), impregnated with phenol-formaldehyde binder.

These materials     are designed for production (by compression and transfer molding) articles withstanding temperatures from -196 °C to +200 °C and conditions of tropical climate .  

Advantages: unlike other materials of the same type, these ones offer higher bulk weight, improved processing ability; they don’t need any preparation before processing. 

Molding compounds are nontoxic; non-explosion and they are classified as materials with low degree of inflammability.
