What we commonly seeExplosion proof shellMost of them are made of metal materials, can we use plastic as an explosion-proof shell?
Explosion proof products can use plastic as the outer 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 plastic material will change when it is exposed to cold and heat. Therefore, additional tests are needed, 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 difficult for plastic materials to meet these testing requirements at present, so we still recommend that customers use metal shell materials
