USA Sealing G-11 Garolite Sheet 1/8″ Green 12″ Square Laminates

Description

Product Overview

The USA Sealing G-11 Garolite sheet is engineered from premium G-11 fiberglass epoxy laminate, delivering a robust 1/8″ (0.125″) thickness in a distinctive green color. This sheet measures 12″ x 12″ x 12″ and weighs just under 2 pounds, making it both sturdy and manageable for a wide range of industrial tasks. Its composition combines high‑modulus glass fibers with a phenolic‑based epoxy resin, resulting in a material that meets UL 94 HB flame‑rating standards and offers a Rockwell M110 hardness.

Key physical attributes include a tensile strength of 37,000 psi, an impact strength rating of 12 ft‑lb/in, and a low water absorption rate of 0.005, which classifies its moisture resistance as poor but acceptable for dry‑environment applications. The sheet tolerates temperatures up to 300 °F, ensuring stable performance in heated processes such as molding, machining, and thermal forming. Its density of 0.066 lb/cu in provides a lightweight yet durable platform for precision engineering.

Manufactured by USA Sealing Inc., this laminate is part of the standard grade series, offering a plain backing type that simplifies bonding to adhesives, tapes, or mechanical fasteners. The product is not discontinued and remains available for bulk orders, with a best‑seller rank indicating strong demand within the laminate sheets category. Its dimensions and tolerances—±0.005″ thickness, ±0.25″ width and length—provide consistency across large production runs.

Designed for versatility, the G-11 Garolite sheet excels in applications requiring high strength, dimensional stability, and resistance to wear. Whether used as a base for printed circuit boards, a protective layer in tooling, or a component in aerospace fixtures, the material’s combination of mechanical and thermal properties makes it a reliable choice for engineers seeking performance without compromise.

Usage

In the aerospace sector, the G-11 sheet serves as a structural insert for aircraft panels, providing a lightweight yet high‑strength solution that tolerates the temperature fluctuations encountered at altitude. Its low coefficient of friction and excellent impact resistance allow it to absorb shock loads without cracking, making it suitable for mounting brackets, vibration dampening pads, and protective shields.

Electrical engineers value the sheet for its dielectric properties, employing it as an insulating substrate in high‑voltage equipment, transformer housings, and circuit board laminates. The material’s non‑conductive nature, combined with its flame‑rating compliance, ensures safety in environments where electrical isolation and fire resistance are critical.

Manufacturing facilities leverage the sheet for tooling applications such as molds, dies, and jigs. The 1/8″ thickness offers a balance between rigidity and ease of machining, allowing CNC routers and laser cutters to shape the material with precision. Its resistance to wear and impact extends tool life, reducing downtime and maintenance costs.

In addition, the sheet’s ability to withstand temperatures up to 300 °F makes it appropriate for heat‑treated processes, including composite lay‑up curing, metal forming, and laboratory testing rigs. Users can rely on its dimensional stability even when exposed to moderate heat, ensuring consistent results across repeated cycles.

FAQ

What is the recommended adhesive for bonding the G-11 sheet?

We recommend using a two‑part epoxy adhesive that is compatible with phenolic‑based resins. The adhesive should be applied in a thin, even layer and cured according to the manufacturer’s temperature schedule to achieve optimal bond strength.

Can the sheet be machined with standard CNC equipment?

Yes, the 1/8″ thickness is well‑suited for CNC routing, drilling, and laser cutting. Use carbide‑tipped tools and maintain proper feed rates to avoid delamination. Cooling with compressed air or mist helps reduce heat buildup.

Is the material suitable for outdoor exposure?

While the sheet offers good mechanical properties, its water absorption rating is low, making it less ideal for prolonged moisture exposure. For outdoor applications, consider applying a protective coating or selecting a moisture‑resistant variant.

What certifications does the G-11 sheet hold?

The sheet complies with UL 94 HB flame‑rating standards and meets industry specifications for hardness (Rockwell M110) and density. It also conforms to the dimensional tolerances required for precision engineering projects.

How does the sheet perform in high‑frequency electrical environments?

Its dielectric strength and low dielectric loss make it suitable for high‑frequency circuits and RF components. The material’s stable permittivity ensures consistent signal integrity across a range of frequencies.
