NP130 Glass Epoxy Laminate Sheet is a NEMA Grade FR-4 glass epoxy laminate produced to printed circuit board quality standards, constructed from woven glass fabric impregnated with a halogenated epoxy resin system.
Produced to PCB quality standards means tighter control over dimensional consistency, resin distribution, and surface quality compared to general-purpose FR-4 laminates — making NP130 the appropriate choice where FR-4 material must meet PCB substrate-level manufacturing controls.
The material achieves the highest lengthwise flexural strength (80,000 psi) and highest Izod impact strength (15.00 / 12.00 ft-lb/in LW/CW) in the FR-4 laminate family, along with a Tg of 135°C — 5°C above standard NP510A.
Compressive strength is 70,000 psi flatwise and bonding strength 2,200 lb. Breakdown voltage reaches 65 kV (Condition A), electric strength is 670 Volts/mil (Condition A), arc resistance is 120 seconds, and comparative tracking index is 150 V. Dissipation factor at 1 MHz is 0.025 and relative permittivity is 4.80. The CTE is 10.0 / 12.0 (“/”/°C × 10⁻⁶, X/Y-axis). Moisture absorption is 0.10% and flammability is V-0. NP130 is not UL Listed.
Certifiable to MIL-I-24768/27 Type GEE-F, ANSI/NEMA IM 60000-2021 Grade FR-4, IEC 60893-3-2 PE GC 202, ASTM D709 Type FR-4, and IPC 4101/21.
What differentiates NP130 Glass Epoxy Laminate Sheet from NP510A (FR-4)?
NP130 is produced to printed circuit board quality standards and achieves higher flexural strength (80,000 / 60,000 psi LW/CW vs. 65,000 / 52,000 psi for NP510A), higher tensile strength (50,000 / 40,000 psi vs. 40,000 / 32,000 psi), higher Izod impact strength (15.00 / 12.00 ft-lb/in vs. 7.90 / 7.30 ft-lb/in), and a higher Tg (135°C vs. 130°C). However, NP130 is not UL Listed, while NP510A is UL Listed for thicknesses greater than 0.029". NP130 is the choice where maximum mechanical performance and PCB quality standards are the primary drivers; NP510A is the choice where UL Listing is required.
Why does PCB quality production standard matter for a structural laminate?
PCB quality standards impose tighter controls on resin uniformity, thickness tolerance, fiber-to-resin ratio, and surface condition than general-purpose laminate production. For structural and electrical insulation applications where dimensional precision, surface finish, and consistent dielectric properties across the panel are critical — such as test fixtures, precision-machined insulators, and PCB substrates — the tighter production controls of a PCB-quality laminate reduce lot-to-lot variation and improve downstream manufacturing yield.
What is the temperature index for NP130 Glass Epoxy Laminate Sheet?
The temperature index is 130°C electrical / 140°C mechanical, as listed on the Technical Datasheet.
Is NP130 Glass Epoxy Laminate Sheet suitable for military, PCB, and regulated electrical environments?
Yes. NP130 is certifiable to MIL-I-24768/27 Type GEE-F, ANSI/NEMA IM 60000-2021 Grade FR-4, IEC 60893-3-2 PE GC 202, ASTM D709 Type FR-4, and IPC 4101/21, and achieves a UL 94 V-0 flammability rating. Note that NP130 is not UL Listed.
How should NP130 Glass Epoxy Laminate Sheet be specified?
Specify grade (NP130 Glass Epoxy Laminate Sheet), thickness, compliance requirements (NEMA FR-4, MIL-I-24768/27, IPC 4101/21, or other applicable standards), dimensional tolerances, and finished format.
