Product Description
The product shell is made of FRP, which is an anisotropic material, plus its formula and additives have a wide range of selectivity. According to the working environment and state of FRP, special flame retardant additives are added to make the FRP material have good resistance. flammability, explosion-proof, corrosion resistance, long life and other advantages. In the environment of -50C-+150ºC, it can still maintain good physical and mechanical capabilities, protection grade IP55, maintenance-free.
