Rubber Resources Maastricht has developed a new type of reclaim for specific use. Ecorr® RCR is a new grade of reclaim solely produced from bladders, and the initial approach is to re-use it in bladder compounds. Therefore, Ecorr® RCR has been tested in a curing bladder compound. The compound test results have revealed the multiple benefits of this reclaim grade.
It can be concluded that the use of Ecorr® RCR in a bladder compound leads to a reduction of 8 - 10% in raw material costs, whilst retaining product properties. Especially, regarding tensile properties and air permeability the test provided very promising benefits. If the percentage of savings is converted to actual value, cost savings come down to 0,06 - 0,12 usd/kg.
