Under the pressure of high polymer costs fine rubber powder is being continually evaluated in a range of applications

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.

Process	Example Polymers	Methods	Comments
Injection Moulding	PP, PE, PU, rubber	As a raw material blended with other polymers.	Needs to be compounded (please follow link to Verneos)
Sheet or profile extrusion	PVC, TPE, PU, rubber	As a composite material or added during processing,	Non slip surface
Co -extrusion	PVC,TPE,PU, rubber	Added during processing In middle layer,	Reduce weight on PVC. Maintains aesthetics
Compression Moulding	PU, rubber	As a composite material blended with other polymers.	Reduces cost, in rubber maintains compression set
Spray	PU, Bitumen	Either blended or introduced at point of use.	In PU reduces cure time
Roll on	PU, Latex, Bitumen	Introduced at point of use	Non slip surface
Paint On	Bitumen, PU, Acrylic	Either blended or introduced at point of use.
Rotational Moulding	PE	Added during processing
Blown film			No advantages

Crumb Rubber has invested heavily in investigation of the right techniques, expertise, and products, to make rubber powder a cost effective part of your process.
