Difference Between 3240 and FR-4 Epoxy Board

What is the difference between FR-4 epoxy board and 3240 epoxy board? Difference between 3240 and FR-4
There are many types of epoxy boards in our insulation materials industry. Each epoxy board has unique properties to meet the requirements of different industries, such as G10, G11, 3240, FR 4, etc., since they are all insulating materials. But what’s the difference? Today we focus on analyzing the differences between 3240 and FR-4.
First of all, you need to know that 3 of the 3240 epoxy board represents a laminated product, which is also said to be made by pressing multiple layers of cloth. 2 stands for inorganic substrate, 4 stands for its maximum use temperature of 155 degrees, heat resistance class belongs to B class, 0 stands for the code of product type. Therefore, the full name of 3240 epoxy board is epoxy laminated glass cloth board. It is widely used in the manufacture of electrical and mechanical insulation parts.
FR4
G in G10 epoxy board is the English abbreviation of glass fiber. The number 10 represents the content of glass fiber at 10%. G10 is synthesized from imported electronic-grade glass fiber cloth and imported epoxy resin. Flame retardant grade UL94-VO, can withstand high temperature of 180 degrees, high temperature of 288 degrees in a short time, good mechanical properties at high temperatures, with a certain strength, acid and alkali resistance, waterproof and good insulation properties. As an ordinary electrical insulation part manufacturing, the 3240 epoxy board can basically meet the common electrical insulators in life. The G10 epoxy board meets certain requirements for insulation performance and electrical equipment with high temperature resistance. Obviously, the performance of G10 epoxy board is better than 3240 epoxy board.
