PVC (polyvinyl chloride) chemical and physical properties of rigid PVC is one of the most widely used plastic material. PVC material is a non-crystalline materials. PVC materials actually used often by adding stabilizers, lubricants, auxiliary agent, impact agent and other additives for PVC material is not flammable, high strength, good resistance to climate change as well as geometric stability. PVC to oxidizing agents, reducing agents and strong acids have very strong powers of resistance. However it can be strong oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid corrosion and does not apply where in contact with aromatic hydrocarbons, chlorinated hydrocarbons.
