Can explosion-proof products use plastic as the outer shell?

Our common explosion-proof shells are mostly made of metal materials. Can we use plastic as the 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 met……

Why do products need explosion-proof certification?
