Processes

Crumb Rubber has made considerable investment in developing successful cost effective solutions in a range of polymer processes, including injection moulding, extrusion, co-extrusion, compression moulding, thermoforming and many others (please see the table below).

Crumb Rubber’s associate company Verneos, for example, has developed a wide range of polyolefin based materials that incorporate rubber powder. These typically make cost effective alternatives to many grades of polypropylene, thermoplastic elastomers and PVC.

The quality and cleanliness of the rubber powder supplied by Crumb Rubber provides the user with a versatile and cost effective raw material that can add benefit in most polymer applications.
