What we commonly seeExplosion proof shellMost of them are made of metal material, can we use plastic as the explosion-proof shell?

Explosion proof products can use plastic as the shell, but because the strength of plastic is not as high as that of metal, the plastic shell of the same product is generally thicker than the metal shell, and the strength of the plastic material will change when it is heated or cooled. Therefore, additional tests need to be conducted, such asHeat and cold resistance test，Surface resistance testThe requirements for light resistance and emulsion resistance are also required for Class I equipment. However, in reality, it is currently difficult for plastic materials to meet these testing requirements, so we still recommend customers to use metal shell materials
