Phenolic Fiberglass Sheets
Phenolic fiberglass sheet is a novel composite material produced through a specialized process, utilizing phenolic resin as the matrix and glass fibers as the reinforcing material. Phenolic resin is a common synthetic resin primarily composed of phenols and aldehydes. It possesses excellent properties such as abrasion resistance, thermal stability, electrical insulation, and chemical stability. When combined with glass fiber, phenolic resin forms a composite material that combines the superior flame retardancy and heat resistance of the resin with the high strength and high modulus of the glass fiber. It is widely utilized across various fields, including industry, construction, and electrical engineering.

Gel-Coated Sheets
A layer of gel coat applied on the surface, providing a smooth finish and improved appearance and weather resistance.
Anti-Slip Sheets
The surface is embossed with anti-slip textures, mainly used for flooring applications.
Notes
- Phenolic resins and additives may contain hazardous substances; therefore, appropriate safety protocols must be observed—such as wearing protective gloves and eyewear, and maintaining a well-ventilated work environment.
- During use, prolonged contact with high-temperature objects should be avoided to prevent compromising the performance properties of the composite material.
- Discarded phenolic fiberglass composite materials must be properly processed and disposed of in accordance with local environmental regulations.
