Questions about Thermoset Composites?

UL Listed Dielectric And Flame Resistant Thermoset Composites


These materials are suitable for electrical applications requiring a composite material with a UL Yellow card and low flammability performance.


Rosite™ and Dielectrite™ standard polyester composites offer a wide range of physical, mechanical, electrical and thermal performance characteristics in the combinations needed to meet most product specifications. Custom formulations, in virtually any quantity, can be developed.

These materials can be found in Underwriters Laboratory file E53587.


Rosite™

Rosite UL Listed High Performance Composites

Rosite™ materials are formulated for molding to very tight tolerances. Shrink-controlled materials can hold tolerances of 0.05%. Rosite™ high performance electrical composites have good dimensional stability (creep resistance), even at elevated temperatures.

Proprietary ingredients enhance the fire quenching characteristics of Rosite™ thermoset polyester composites. Gases released by an electrical arc help suppress arcing and allow the interruption ratings of electrical switching and safety devices to be increased.

High strength Rosite™ BMC composites are suitable for use in applications requiring flammability performance from UL94 HB, V-0 & 5VA. Rosite™ thermoset composites are formulated to provide outstanding thermal performance with Relative Thermal Index (RTI) rating of 130°C – 180°C.

Dielectrite™

Dielectrite UL Listed High Performance Composites

Dielectrite™ is suitable for electrical applications requiring a composite material that possesses a UL Yellow card and flammability performance from UL94 HB, V-0 & 5VA.

Dielectrite™ is available as either a sheet molding compound or bulk molding compound to suit your needs.
