Chemical protective clothing may or may not be hermetically sealed, depending on the application and the level of hazard. All materials used in protective clothing must be resistant to chemical penetration and degradation. Seam structure is also an important factor affecting the performance of protective clothing, if the treatment is not good, the needle of the fabric will leave enough pores to allow small materials or liquids to pass through. Thus, the protection performance is reduced.

Chemical protective clothing is divided into two categories: light and heavy.

Airtight protective clothing is generally made of neoprene rubber, which is corrosion resistant to a variety of different chemicals and is very suitable for working in cold and high temperature environments. Heavy protective clothing is generally equipped with respirators, and the weight of protective clothing is generally about 6 kilograms.
