It is a lightweight, durable board synthesized from glass-fiber material and high-heat-resistance composite resin, with no asbestos content. The dense glass-reinforced structure gives it high mechanical and dielectric (electrical-insulation) properties, strong heat and moisture resistance, a smooth pit-free surface and excellent processability for drilling and machining. Because it resists corrosion, humidity and temperature swings far better than wood or cork, it is widely used for molding, electronics fixtures and industrial/building insulation — a cost-effective alternative to metal or laminate boards.
Woven glass-fiber layers bonded with heat-resistant resin form a dense, void-free board.
Between mold and machine it keeps the mold cool, shortening cycles and saving energy.

Wonclean designs and manufactures FR-4 glass-fiber boards and modular cleanroom systems with its own production base and in-house engineering team, shipping to customers in 40+ countries. We cut boards to your size, thickness and color, and back every order with responsive technical support.
Injection molding needs high-temperature material but a low-temperature mold. Installing our FR-4 insulation plate between the mold and the machine keeps the mold cool and prevents the machine from overheating — ensuring stable product quality and better energy efficiency, with shorter production cycles.
It offers stable electrical-insulation (dielectric) performance and a smooth, pit-free surface with thickness tolerances that exceed typical industry standards — making it ideal for precision PCB test racks, ICT fixtures and star wheels.
Yes. Thanks to high moisture resistance and a low moisture-absorption rate, the boards suit ventilation ducts and large wall/ceiling insulation areas without deteriorating, warping or growing mildew the way wood or cork can.
It is rated for continuous service from −30°C to +150°C, giving stable mechanical and insulation performance across cold-storage and high-temperature industrial applications alike.
Yes. The board is asbestos-free and contains no components harmful to human health, while its surface can be steam-cleaned for hygienic, low-maintenance use.
