Rubber Process Oils
ELASTO SUPREME (TRAE)
RUBBER PROCESS OILS
HP ELASTO SUPREME
Aromatic process oils are primarily used in the manufacture of tyres. A typical tyre tread may contain a substantial weight of this aromatic extender Oil. These oils contain Poly Aromatic Hydrocarbons (PAH) / Polycylic Aromatic Hydrocarbons (PCA). It has been scientifically proved that a PCA Content of more than 3% weight is directly proportional to the risk of cancer in human beings. The PCAs are released to the environment during the process of tyre wear and manufacture.
The content of PCA/PAH need to be controlled to ensure that the product does not damage the environment. ELASTO SUPREME is a treated residual aromatic extract (TRAE) type product which has been designed to prevent damage to the environment and at the same time contribute to the high end performance of modern automobile tyre and Styrene Butadiene Rubber (SBR).
