There are many types of epoxy boards in our insulation industry, each of which has unique properties to meet the requirements of different industries, such as G10, G11, 3240, FR-4, etc., since they are all insulation Material, but not the same.
First of all, you need to know that 3 of the 3240 epoxy board represents a laminate, which is said to be pressed from a multi-layer fabric. 2 represents an inorganic substrate plate, 4 means that its use temperature is up to 155 degrees, heat resistance grade is B grade, and 0 represents the code name of the product type. Therefore, the full name of the 3240 epoxy board is epoxy laminated glass cloth board. It is widely used in the manufacture of electrical and mechanical insulation parts, and its performance is general. It belongs to domestic epoxy board.
                                         
G in G10 is the English glass fiber abbreviation of glass fiber, the number 10 represents the content of glass fiber is 10%, G10 is synthesized by imported electronic grade glass fiber cloth and imported epoxy resin, with high technology and superior performance. Flame-retardant grade UL94-VO grade, can withstand 180 degrees high temperature, can withstand 288 degrees of high temperature in a short time, good mechanical properties at high temperature, with certain strength, acid and alkali resistance, waterproof and good insulation properties.
As an ordinary electrical insulation parts manufacturing, 3240 epoxy board can basically meet the common electrical insulation of life. G10 fr4 glass epoxy sheet meets certain requirements for insulation performance and electrical equipment with high temperature resistance. The performance of G10 epoxy board exceeds 3240 epoxy board, and the price of G10 Fiberglass Sheet is also higher.
