     The aromatic nucleus structure and high-crossing link density characteristic have good heat-resistance after phenolic resin solidification. Although under high temperature, it could keep its  wholeness structure and stable size. The phenolic resin is stable under 200°CIt could long-term use under 180°C.

The phenolic resin has an important role as adhesives. The adhesives of phenolic resin depends on macromolecular structure polar group. When phenolic resin composite material process into final products, the phenolic resin adhesives has changed into net structure and solidification to ensure the bond interface stabilization and lasting. Phenolic resin is the first choice of electric industry, it can endure short circuit and keep on working. It may suffer electric shock and carbonization, but it never burn. And it could overcome arc strike.

 The phenolic resin has good fire resistance and most of macromolecule resin are easy to burn, they need to add fire retardant to achieve fire resistance except phenolic resin. It could not add fire retardant. Phenolic resin has good insulationg property who could mix with any reinforcing material. It is equipped with high compression strength to make into circuit board. Different reinforcing material could meet different circuit board.
