in 1872, German chemist bayer ( 一个。 Baeyer) Phenolic resin was synthesized in the first place. Phenolic resin is the most important feature is the high temperature resistance, even at very high temperatures, can maintain the stability of the integrity of the structure and size. Is for this reason, the phenolic resin was used in some high temperature fields, such as refractory material, friction material, binder and casting industry.
the production and use of phenolic resin can bring a certain degree of pollution to environment, and affect the ecological environment, however note or strengthen pollution, including wastewater treatment and recycling of waste phenolic resin product and its composites, phenolic resin can make the healthy and rapid development. Phenolic board the main raw material is phenolic resin, and its safety, green image has construction department and the public security fire department approval.
