NP510A is a woven glass fabric composite combined with epoxy resin system. It is engineered to provide NEMA grade FR-4 properties. This material contains bromine on the epoxy resin backbone. NP510A is certifiable to MIL-I-24768/27, Type GEE-F.

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.

NP613 is constructed from electrical grade of kraft paper and a 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 machining grade for structural and mechanical applications. NP310HT has better impact strength than phenolic paper grades. It meets the requirements of MIL-I-24768/16, IEC-60893-4-PF CC 201 and is designed to meet GE specification A19B15B1.

Grade RT628 is an improved machining grade meeting NEMA XX for tubes. It has low moisture absorption and good dimensional stability. Typical applications are as a replacement for RT629 where improved machining characteristics are needed. The primary application is in transformers. Certification to IEC standard is pending.

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.

Being a hot oil treated version of RTB320, RTB320S has low moisture absorption and excellent dimensional stability. Typical uses include bearings and applications that require fine machining characteristics. Certification to IEC standard is pending.

Bleached canvas phenolic laminate with graphite added as a solid lubricant. This material has improved wear properties under certain conditions. Better moisture absorption and machinability than NP315. Material is conductive to electricity and should not be used where this is detrimental to the application.

NP511 consists of a woven glass fabric combined with high temperature epoxy resin system. NP511 has excellent mechanical strength and electrical properties from cryogenic to elevated temperatures. Continuous operating temperature is 175°C. This material meets NEMA G-11, MIL-I-24768/3, Type GEB and IEC-60893-3-2 EP GC 203.

Grade RTB320 has low moisture absorption and excellent dimensional stability. Produced with a bleached linen and a phenolic resin system, it's typical uses include retainers for ball-bearings and applications that require fine machining characteristics. RTB320 also complies with MIL-I-24768/13, Type FBE, ASTM D709 Type II Grade LE and with IEC 61212-3-1 PF CC 21.

NP630 is a fine machining grade with excellent electrical properties and moisture resistance. It has low cold flow with good dimensional stability.

Warm punching, composite grade with woven glass covers for improved flexural, tensile and impact strength. It has better electrical properties and higher mechanical strength than NP611.
