Special Boiling Point Spirit 55/115
Special Boiling Point Spirit 55/115 - The primary use of SBP Spirit 55/115 is in the rubber industry particularly during the process of vulcanization in tyre manufacturing. It also finds usage in a variety of other applications like -
-
Preparation of certain rubber mixes, cements and adhesives,
-
Thinner for varnish, paint and printing inks formulation where quick drying is required
-
Diluent for lacquer, enamels, high grade leather drops
-
Solvent for processing polishes, cleaning and water proofing compounds
-
Solvent for dry cleaning where quick drying time and reduced residual odour are desired
-
Fuel in gas generation plants

FOOD GRADE HEXANE
Hexane is a colourless solvent. Food grade Hexane is primarily used in the extraction of Edible Oils. This calls for very high purity levels of Hexane, followed by safe and careful storage, handling and transportation right from production to end use. It also finds usage in a limited manner in preparation of rubber adhesives, can sealing compounds etc.

Petrochemicals
BPCL has taken up integrated refinery expansion project (IREP) to enhance the capacity of its Kochi Refinery from 9.5 MMTPA currently to 15.5 MMTPA. The Refinery at Kochi, post expansion, will produce 0.5 Million Tonnes of Propylene which it plans to utilize by producing high value niche petrochemicals like Acrylic Acid and its derivatives like Acrylates, Oxo-alcohols & Super Absorbant Polymer (SAP).
BPCL will engage in marketing of the following grades of Petrochemicals:
-
Acrylic Acid (AA)
-
Butylacrylate Monomer (BAM)
-
2 Ethylhexyl acrylate (2EHA)
-
2 Ethylhexanol (2EH)
