Typical applications include insulation in power generation equipment and other structural applications when used in elevated temperatures. MC511AF is certifiable to MIL-I-24768/3, Type GEB.

A paper-base laminate with low phenolic resin content for hard, flat surfaces. This material is most commonly used for drill entry material in the PCB industry.

MC511A is a high strength, glass epoxy laminate that is specially formulated to meet power generation producer’s exacting standards where higher strength at elevated temperatures are required. MC511A is certifiable to MIL-I-24768/3, Type GEB, IEC-60893-3-2 EP GC 203 and is halogen free to meet the European restrictions.

NP643 is constructed from an electrical grade kraft paper and a high temperature specially modified epoxy resin system. It is designed to be used in tap changers, coil support plates and terminal panels for transformers and their accessories.

Canvas phenolic laminate with molybdenum disulphide added as a solid lubricant. This material has improved wear properties under certain conditions. Material is semi-conductive to electricity and should no be used where this is detrimental to the application.

A paper-base laminate with low phenolic resin content for hard, flat surfaces. This material is normally used in the printed circuit board industry as a backup for the drilling operation. However, it is also used in other industries for tooling stock because of its ease of machining and good dimensional stability.

RT507F is manufactured using a fine weave glass fabric combined with a silicone resin system. It has excellent electrical properties under humid conditions, superior heat and arc resistance. Typical applications include heating appliance insulation, welding equipment nozzle insulation, heat barriers and specialty bearing applications. The fine weave fabric substrate provides a “finer” finish on the surface of the finished part. RT507F also complies with MIL-I-24768/17, Type GSG and ASTM D709 Type IV Grade G-7.

Being a heat treated version of RT628, RT628H is an improved machining grade meeting NEMA XX for tubes. It has low moisture absorption and good dimensional stability.
