Good expansibility: When the heat reaches a certain temperature (initial expansion temperature, generally around 160-280 ° C, according to the grade of the material), it begins to expand, and the expansion volume can reach more than 200 tim
es the initial.
Excellent physical and chemical properties: good pressure resistance, flexibility, plasticity, self-lubrication, high/low temperature resistance, corrosion resistance, radiation resistance, earthquake resistance, excellent electrical conductivity, can resist the melting and penetration of various metals, chemical stability.
Environmentally friendly: It does not contain halogenated additives, dangerous heavy metals such as lead or chromium, and is environmentally friendly.
Application in fireproof coatings
Flame retardant heat insulation: When the fire occurs, the expanded graphite expands rapidly, forming a large amount of light non-combustible carbon layer, blocking heat radiation to the substrate, while the acid release inside the sandwich promotes the carbonization of the substrate, and achieves good flame retardant effect through a variety of ways to protect the substrate.
Anti-static: Because graphite is a good electrical conductor, the addition of expanded graphite coatings can prevent the accumulation of electrostatic charges, such as for oil storage tanks, can achieve the dual effect of fire and anti-static.
Improve the performance of the coating: its fine particles are added to the ordinary coating, which can be made into flame retardant anti-static coating, improve the high temperature resistance and fire resistance of the coating, and compatible with a variety of polymer coating systems, suitable for epoxy resin, emulsion, silicone and other coating systems.
