The addition of domestic FR4 1000 * 2000 * 1mm fiberglass epoxy resin board sheet determines its excellent performance. Because of its excellent mechanical properties, domestic FR4 1000 * 2000 * 1mm epoxy resin board has excellent rigidity, as hard as steel, remarkable toughness and good elasticity. Of course, domestic FR4 1000 * 2000 * 1mm epoxy resin board can also withstand very strong impact force. Another point is that the creep resistance of epoxy plates is very prominent in the material stability. In addition to the variety of forms, easy curing, strong adhesion, low shrinkage, domestic FR4 1000 * 2000 * 1mm epoxy resin boards are widely used as high insulation parts for machinery, electrical appliances and electronics.

Of course, these are all essential additions to the epoxy plate. The main component of domestic FR4 1000 * 2000 * 1mm epoxy resin board is epoxy resin, which is laminated insulating board after glass cloth is combined with epoxy resin. Curing agent, modifier, filler, diluent and other additives play an important role in determining the performance of epoxy board. Because they are an essential addition to epoxy resin, which determines whether the product can be formed and cured. If it cannot be formed and cured, there will be no epoxy plate.

Through the performance regulation of the additive, the domestic FR4 1000 * 2000 * 1mm epoxy resin board can be applied in more fields. Epoxy plates can be diversified from extremely low viscosity to high melting point solids by changing the ratio of additives, and can be cured in almost any temperature range from 0℃ to 180℃.

The use of additives enables the domestic FR4 1000 * 2000 * 1mm epoxy resin board to react in an environmentally friendly way, with no release of water or any volatile side effects and low shrinkage. In this way, the resulting internal stress is also relatively reduced, thus contributing to a significant increase in the adhesion strength of the epoxy plate. Of course, there are side effects. The epoxy itself is non-toxic. However, as the demand changes, the type and composition of additives vary, the properties of the epoxy resin will change, which will make the domestic FR4 1000 * 2000 * 1mm epoxy resin board toxic. Therefore, attention must be paid. This is also the reason why LCP, which has excellent wear resistance and wear reduction, replaces epoxy plate as the packaging material of coil skeleton to some extent by adding high filler as the packaging material of integrated circuit.
