PVC pipes used in water supply, plumbing, construction, and industrial applications require thermal stability, mechanical strength, durability, and consistent surface quality.

The proper selection of additives plays an important role in the production of high-quality PVC pipes. PVC heat stabilizers help protect the material from thermal degradation and discoloration during processing, while internal lubricants and PVC processing aids support melting, gelation, dispersion, and processing efficiency.

For certain rigid PVC pipe formulations, impact modifiers can also be used to improve resistance to impact and mechanical stress.
