How does the epoxy board manufacturer look at the quality of the epoxy board? The first thing to look at is the appearance of the epoxy. The color, strength and toughness, insulation performance are also important.

Epoxy board is a laminated board, which is mainly made of epoxy resin binder and paper, cotton and other substrates. There are many types of epoxy boards, including 3240 epoxy boards, G11 epoxy boards, G10 epoxy boards and FR-4 epoxy boards, etc. They have similar properties but differ in detail.

Also, the sides of the crosscut should be neat, some rough edges have burrs and are sticking. Epoxy panels are colored, including aqua, yellow, black and white, etc. The epoxy should look uniform and full in color. The epoxy has strong strength and good toughness, you can try to bend it or force it when you test its performance. If it's weak and easy to fold, its quality is not good. Epoxy is waterproof and resistant to chemical corrosion, and can work well in wet environment. So this can also be used to test its performance. As an insulating material, insulation performance must be good, non-conductive, even in harsh environments.

The quality of the epoxy board is basically to see the above points. If the appearance is beautiful, and physical and chemical properties are good, the quality will be good. A lot of poor quality epoxy boards can be seen from their appearance. In the mixed market, we also need to learn relevant knowledge if we want some product, so as not to be deceived by others.
