FR4 Epoxy-Sheet Resin Glass-Fiber Insulation-Plate – 335X300X10MM Green

Description

Product Overview

The FR4 epoxy sheet from Ciwenkai is engineered as a high-performance insulation plate that combines a robust epoxy resin matrix with woven glass‑fiber reinforcement. Measuring 335 × 300 × 10 mm, the green‑colored sheet delivers a consistent 10 mm thickness, providing a stable platform for a wide range of electrical and mechanical applications. Its formulation meets industrial‑grade standards for flame retardancy, dielectric strength, and thermal stability, ensuring reliable operation even in harsh environments where temperature fluctuations and electrical stress are common.

Manufactured using a precision lamination process, each sheet exhibits uniform fiber distribution and minimal void content, which translates into superior mechanical strength and dimensional accuracy. The epoxy resin component offers excellent resistance to moisture absorption and chemical exposure, while the glass‑fiber layer contributes to high tensile strength and rigidity. This combination makes the product suitable for both primary structural roles and secondary reinforcement tasks in complex assemblies.

Beyond its core material advantages, the sheet is designed for ease of handling. Its surface finish is smooth enough for direct machining, drilling, and routing without excessive tool wear, yet it retains enough toughness to resist chipping during aggressive processing. The product is supplied in a single‑piece package, with each unit carefully inspected for conformity to the specified dimensions and performance criteria.

Usage

Engineers and technicians frequently select this FR4 sheet for motor housings, where its insulating properties protect windings and electronic controls from short circuits while withstanding the heat generated during operation. In printed circuit board (PCB) manufacturing, the sheet serves as a reliable substrate for multilayer boards, providing a stable base that supports fine trace routing and component placement without deformation.

Renewable energy sectors, such as wind‑power and hydro‑power installations, benefit from the sheet’s durability and resistance to environmental stressors. It can be used as a protective barrier in inverter housings, transformer cores, and control panels, where long‑term reliability is essential. Additionally, the sheet is suitable for aerospace and rail‑transit applications, where weight‑to‑strength ratios and fire safety certifications are critical considerations.

In laboratory and prototyping environments, the material’s ease of machining allows rapid iteration of custom fixtures, test plates, and isolation pads. Its compatibility with standard adhesives and fasteners further simplifies integration into existing designs, reducing lead times and overall project costs.
