The difference between Fr4 Fiber Glass Epoxy Sheet and 3240 epoxy board?
1. The material of FR4 Epoxy Fiber Glass Sheet belongs to glass fiber, and the material of 3240 belongs to epoxy resin. And fr4 is heat-resistant, and its performance is better than 3240. The general color of fr4 is water green, and the color of 3240 is yellow.
2. The color of the FR4 epoxy board is very natural, a bit jade-like, while the color of the 3240 epoxy board is a bit blinking.
3. FR4 is an improved product of 3240 epoxy board. The flame retardant performance of FR4 epoxy board complies with the national UL94V-0 standard. 3240 epoxy board has no flame retardant properties.
4. G10 Fr4 Insulate Sheet can have the function of natural extinguishing in case of fire.
5. The dimensional stability of FR4 is better than that of 3240, and during the pressing process, the thickness tolerance control of FR4 is also much better than that of 3240, which is more suitable for processing.
6. 3240 epoxy board contains halogen, which is not very environmentally friendly for the environment and human body. It is also not in line with the country's green sustainable development strategy. The FR4 epoxy board is just the opposite.
