The Processing of PVC, and some Facilitates

Polyvinyl Chloride (PVC) is one of the most widely used polymers in the world. It is an odorless, brittle thermoplastic, which is lightweight and easy to handle. PVC takes less non-renewable fossil fuel to make than any other commodity plastic, compared to plastics such as PE, PP, PET and PS, which are totally dependent on oil or gas, thereby favoring the production of P...

In PVC products, CaCO3 is added for two reasons: to reduce the cost and to provide functional properties. Viscosity of PVC compound is important from a processing point of view. It increases with the addition of filler because CaCO3 does not melt during processing. From a product application perspective, elastic modulus is a function of particle shape, while impact stren...

Polymerization occurs when a chemical reaction causes molecules to react together to form polymer chains. These polymer chains can be engineered to control the specific physical properties of the resulting plastic resin, thus allowing the product to be designed for many different uses. For example, some plastic products may require extra strength, some require maximum fl...
