PVC (polyvinyl chloride) chemical and physical properties Rigid PVC is one of the most widely used plastic materials.  PVC material is an amorphous material.  In the actual use of PVC materials, stabilizers, lubricants, auxiliary processing agents, colorants, impact resistance agents and other additives are often added.
  Typical uses of medical PVC: water supply pipes, domestic pipes, house wall panels, commercial machine housings, electronic product packaging, medical equipment, food packaging, etc.
     PVC material has non-flammability, high strength, weather resistance and excellent geometric stability.  PVC is very resistant to oxidants, reducing agents and strong acids.  However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid and is also not suitable for the occasions in contact with aromatic hydrocarbons and chlorinated hydrocarbons.
 The melting temperature of PVC during processing is a very important process parameter. If this parameter is improper, it will cause the problem of material decomposition.  The flow characteristics of PVC are quite poor, and its process range is very narrow.  In particular, PVC materials with large molecular weight are more difficult to process (this kind of material usually needs to add lubricant to improve the flow characteristics), so PVC materials with small molecular weight are usually used.  The shrinkage of PVC is quite low, generally 0.2~0.6%.
