Recycling of Rubber
3 Ways to Recycle Rubber

What is Reclaimed Rubber?
IT IS NOT CRUMB OR GRANULATE
IT IS NOT DEVULCANISATION
Description
- Reclaimed Rubber is cured rubber that has passed through a Thermo-Chemical process.
- This process softens and swells the rubber
- The viscosity of the rubber is reduced by shortening the polymer chain by mechanical shear and chemical action
- Yes there are some crosslinks broken
- Yes there are some double bonds broken
How is Reclaim made?
The first recorded reclaiming process dates back to 1846 when Muriate of Lime (Calcium Chloride) was used to remove free sulphur. The first process was the “Pan Process” in 1858. So it’s not a new idea. Although there have been many different methods they all follow a similar path.
Step 1
Collection and Selection of suitable materials
This is probably the most important step. In order to get a uniform and consistent product the correct materials must be selected (contaminant free). This part of the process was overlooked for many years producing inconsistent materials.
Step 2
The rubber has to be reduced in size and any other contaminants removed.
In Tyre Reclaim this consists of removing the bead wire, cutting out the side wall then granulating the remaining materials to below 4mm aiding the removal of textiles and metals In Butyl Reclaim Tubes are de-valved and patches removed before being granulated.
Step 3
Blending
The rubbers are mixed with the chemicals required and the oils needed for the reclaiming process to take place. All the chemicals and oils used today are REACH registered and compliant on PAH’s
Step 4
Digestion.
This is where the materials are subjected to heat to allow the reactions to occur. There are 2 main ways this can be done. In a digester using steam pressure to give 160° C Or Mechanically produce heat.
Step 5
Mastication
Either in the extruder or on a 2 roll mill the rubber is physically worked to break the polymer chain. Also helps refining and blending the reclaim
Step 6
Filtering
The better quality producers at this point extrude the materials through a 60’s mesh (250 µm) filter to remove any undigested materials (nibs)
Step 7
Finishing
The filtered material is either extruded into blocks or is put back on a mill where a paper thin sheet is built up to 15mm thickness before being cut into blocks, coated in antitack agent and weighed off into the desired bundle weight (normally 25 kilos, but any bundle size is possible on request)
Why use Reclaim?
Generally there are 3 main reasons to use Reclaim
- Source of Rubber Hydrocarbon 2. Source of Carbon Black 3. Processing Aid
Rubber Hydrocarbon
Attractive Price
Most obvious reason as Reclaim is less expensive than Virgin Rubber. Reclaim generally contains approx. 50%+ RHC . For every 1% Reclaim you add you save 0.6% on Compound Cost*
- Price Stability Price is not affected by NR and SBR prices.
- Other Savings include reduced mixing times and power consumption
Carbon Black
Tyre reclaim contains approximately 27% of reinforcing Carbon Black
- Easy to use as a Black Pigment Masterbatch
- Much cleaner and easier to handle
Processing Aid
Improved Processing • Uniformity • Low Heat Development • Low Thermoplasticity • Minimum Reversion • Low Swelling and Shrinkage • High Rate of Cure • Good Aging • Good Shape Retention • Improved Tack
Why Reclaim demand fell?
- Tyre Reclaim contains approx. 50% RHC so you compare it to 50% of NR price
- There was a long period of time when Reclaim was not economically attractive
- Quality was inconsistent
- Commercial Rubber production was moving east
- Mixing Technology was improving
- New Technologists knew little or nothing of Reclaim and Crumb
Why is Reclaim now being used more?
From 2000 onwards NR & SBR prices began rising
- By 2003 it became financially attractive
- Users found additional benefits
- Qualities of Reclaim improving
- Green Credentials
Technical advantages of using Reclaim
Shorter Mixing Times • Less Power Consumed • Less Heat Build up • Faster Processing • Low Thermo plasticity • Reduced Swelling and Shrinkage • High Cure Rate • Minimum Reversion • Good Aging
