What high-molecular polymers can be used as fire-resistant material binder?
Lignin is the least expensive.
Melamine resin should be compounded with fire-resistant material and acrylic acid material is easy to burn. But high-molecular polymers can be used along with the above two. Polysulfone is featured by heat resistance and high temperature resistance. Polyurethane is difficult to process and compound with fire-resistant material. Phenolic resin is not easy to burn. Epoxy is expensive and self-extinguishing once away from fire.
