Introduction of Epoxy Glass Sheet:

Epoxy glass cloth laminated sheet is made by chemical treatment of electrician non-alkali glass fiber cloth as the backing material, by hot pressing with epoxy resin as binder and laminated insulations, high mechanical strength under high temperature, high humidity under electrical performance stability is good.

Epoxy Glass Sheet

Applications of Epoxy Glass Sheet:

Appliance Lines, Bearings, Computer Electronics, Electron Lines, Electronic Boards, Gaskets, Gears, Industrial Laminates, Industrial Electronics, Machine Components, Mechanical Lines, Wave Soldering Pallet, Switches, Terminal Boards, Thick Parts, Transformers, Washers, Wear Strips.

Main Series of Epoxy Glass Sheet:

  1. FR-4 epoxy glass sheet is made of glass fiber material and high heat-resistant composite material, and does not contain asbestos components which are harmful to human body. It has high mechanical and dielectric properties, good heat resistance and moisture resistance, and good processability.
  2. G10 poxy glass sheet is a glass fiber and resin laminated composite material, which means that glass fiber contains 10%. G10 material has the characteristics of insulation, corrosion resistance and wear resistance. G10 is a composite material made of glass fiber cloth and epoxy resin. It was originally developed as an aircraft material, which can withstand great forces without breaking deformation. G-10 will not be penetrated by water vapor and liquid, and has the characteristics of insulation, acid and alkali resistance, and weight. G-10 is harder and more expensive than ZYTEL. Generally, it has black, red, blue, green and other colors, and some G-10 have two levels of color at the same time. The texture and performance of G-10 are better than ZYTEL.
  3. G11 poxy glass sheet is made of imported epoxy-free glass fiber cloth impregnated with imported epoxy resin, and added with corresponding imported flame retardants, adhesives and other additives; cardboard-like insulation material processed by hot pressing. Flame retardant grade UL94-VO grade, “ good mechanical properties at high temperature, ” with good processability and insulation properties.Epoxy Glass Sheet
