MOLDING COMPOUNDS DSV-2, DSV-4

Molding compounds DSV -2 and DSV-4 are manufactured of glass strands impregnated with phenol-formaldehyde binder.

Advantages: high mechanical properties, good heat resistance, easy flowing and dosing provide wide utilization of these materials.

Application:   DSV materials are widely used in radio engineering, electrical engineering, aircraft industry, machine building, instrument making industry and also in chemical industry and radio electronics.

High strength details produced of these molding compounds are suitable for operation at temperatures   from  -196 ?C to + 200?C and in conditions of tropical climate.
