PVC (Polyvinyl Chloride) and CPVC (Chlorinated Polyvinyl Chloride) are often recommended for use in applications within corrosive environments due to their exceptional resistance to most mineral acids, bases, salts, and aliphatic hydrocarbons. 

Both materials have excellent strength and rigidity, and their light weight makes installations easier than those with heavier metal options.  CSSI designs and fabricates durable and cost-efficient exhaust systems from PVC and CPVC duct. Type I PVC and CPVC sheets are used for specialty tanks, hoods and other custom equipment.

PVC can be used where temperatures do not exceed 140 degrees Fahrenheit, and CPVC holds its characteristics up to 200 degrees Fahrenheit.  Both are self-extinguishing with a flame spread index of less than 10 and a UL-94 rating.  CPVC also meets Clean Room Materials Flammability Test Protocol (FM 4910).
