FR4 Watergreen Glass Fiber Board

FR4 Watergreen Glass Fiber Board

FR4 boards are laminate products made by impregnating professional electronic fabrics with materials such as epoxy resin under high temperature and pressure. They exhibit excellent mechanical and dielectric properties, along with superior heat resistance, moisture resistance, and flame retardancy, while also offering outstanding machinability. Widely used in motors and electrical equipment as insulating structural components, FR4 boards are integral to various applications—including reinforcement for FPC-based switches, carbon-film printed circuit boards, computer drilling systems, and even mold fixtures (such as PCB test racks). Additionally, they can be safely employed in transformer oil environments, even under humid conditions.

Electrical Bakelite Board

Electrical Bakelite Board

Electrical wood boards, also known as bakelite boards or phenolic laminated paperboards, are made by impregnating insulating paper with phenolic resin, followed by baking and hot-pressing. They exhibit excellent mechanical strength, anti-static properties, and moderate electrical insulation performance. This product is ideally suited for use as insulating structural components in motors and electrical equipment that demand high mechanical performance. It can even be used directly in transformer oil. Additionally, its robust mechanical strength makes it perfect for serving as a backing plate in PCB manufacturing processes, such as drilling operations. Beyond that, it finds applications in distribution boxes, fixture boxes, mold clamps, high- and low-voltage switchgear cabinets, packaging machines, combs, and more. It’s particularly well-suited for use in motors, mechanical molds, PCBs, ICT fixtures, molding machines, drilling machines, and countertop grinding pads.
