PVC - Polyvinylchloride 

A widely used material, its application is under regulation in many countries for ecological reasons and it is often substituted by PP or other polymers. It is chosen for its chemical resistance. 


FEATURES 

High chemical resistance
Higher stiffness compared to polyolefins  
Easy machinability on mechanical tools. It can be hot welded
Colour: grey, ivory, red 


WEAK POINT
 
Compared to PP it has lower shock and temperature resistance. The high gravity reduces its cheapness. 


APPLICATION

Mechanical: it is also used for mechanical components in corrosive environments. Compared to polyolefins, it has a higher tensile stress.

Food contact: it cannot be used in contact with food.
 
Electrical: good dielectric properties and weather resistance make it suitable for these applications.

Chemical: the main application of PVC is in the chemical industry, thanks to its high resistance to acids and alkali and to its rigidity. It is used for components such as valves, flanges, gears, etc. in the chemical, galvanic and petrochemical industries.
