Firstly you will find the obvious compound savings whenusing Ecorr® RBR70.

Value is therefore added next to the easy cost saving.

Secondly by using Ecorr® RBR70 in your halobutyl innerSummaryliner compound you improve the adhesion to the carcass

Advantages
lLower raw material costs.

lLower power consumption and other processing costs resulting from shorter mixing cycles.

lLow calendering, mixing and extrusion temperature.

lReduction of die-swell.

lBetter air venting properties between bladder and inner liner during vulcanisation.

lReduced air permeability in an inner liner (results in reduction of inner liner thickness).

lImproved flex fatigue resistance.

RBR processl

The exclusive feedstock for Ecorr® RBR reclaim mainly consists of 		butyl innertubes.

l

The scrap is collected from a wide network of certified suppliers andis segregated by supplier to ensure identification and traceability.

lApproved raw material
Cutting

In the first phase of our continuous production process the scrap 		
feedstock undergoes a number of cleaning steps, during which it is 		Washingrendered absolutely free of sand, steel, stones and other contaminants.
l

In the second phase, the reclaiming step breaks the sulphur crosslinks

Shredding (down to 3-4 cm)

within the butyl rubber.
l

During subsequent straining and refining steps, non-homogeneous 		Separation of contaminants

particles are removed from the reclaimed rubber to ensure high quality.
l

The result is a rubber compound that can be used as a masterbatch towhich a vulcanisation system is added, or it may be added to a virgincompound, typically at 10-50 phr.
