Special Compounds

Twin-screw extrusion technology is particularly well-suited to make these complex plastics that typically incorporate up to five or six chemical components. Special compounds are polymers with specific base characteristics, usually supplied in granular or pellet form. During the extrusion process, the compounds are enhanced with the addition of different organic or non-organic substances to give them distinctive functional features. These compounds have different characteristics, such as mechanical properties and are used in a variety of post-forming processes such as injection moulding machines, blown film machines, etc.
