USA Sealing G-10 FR4 Garolite Bar Bulk-CS-GFR4-254 0.5in x 4in x 12in

Description

Product Overview

The USA Sealing G-10 FR4 Garolite bar is engineered for demanding industrial applications where strength, durability, and dimensional stability are paramount. Constructed from high‑quality yellow Garolite, a phenolic‑impregnated fiberglass composite, this bar offers a tensile strength of 38,000 psi and an impact strength rating of 14 ft‑lb/in, meeting UL 94 V0 flame‑resistance standards. Its physical dimensions—0.5 in thickness, 4 in width, and 12 in length—provide a versatile form factor suitable for a wide range of machining, prototyping, and assembly processes. The material exhibits a low water absorption rate of 0.0015, ensuring consistent performance in humid or wet environments, and it remains stable across a temperature range up to 280 °F. With a Rockwell hardness of M110 and a density of 0.072 lb/cu in, the bar balances lightweight handling with exceptional mechanical resilience.

Usage

Designed for aerospace, electronics, and high‑performance prototyping, this Garolite bar excels in applications that demand precise machining and reliable electrical insulation. Engineers use it for fabricating custom brackets, stiffening panels, and structural inserts in aircraft interiors, where weight savings and fire safety are critical. In the electronics sector, the bar serves as a substrate for printed circuit boards, RF components, and high‑frequency connectors, providing superior dielectric properties and resistance to thermal cycling. Its excellent impact resistance makes it a preferred choice for tooling, jigs, and fixtures that must endure repeated loading without cracking. Additionally, the bar’s low water absorption and temperature tolerance allow it to be employed in marine and outdoor equipment, where exposure to moisture and temperature fluctuations is common.

FAQ

What machining methods are recommended for this Garolite bar?

Standard machining techniques such as CNC milling, drilling, and routing can be used. It is advisable to employ sharp carbide tools and moderate feed rates to achieve clean cuts and avoid delamination.

Can the bar be used as an electrical insulator?

Yes, the G‑10/FR4 composition provides excellent dielectric strength, making it suitable for insulating components in high‑frequency and high‑voltage applications.

Is the material compatible with adhesive bonding?

The bar’s phenolic resin surface bonds well with epoxy and acrylic adhesives. Surface preparation, such as light sanding and cleaning with isopropyl alcohol, improves bond strength.

What is the temperature limit for continuous operation?

The Garolite bar can operate continuously up to 280 °F (approximately 138 °C) without degradation of its mechanical properties.

How does the bar perform in marine environments?

Its low water absorption and resistance to corrosion make it suitable for marine applications, though additional protective coatings can further extend service life in saltwater conditions.
