On 19
March, Japan’s JSR Corporation and its joint-venture partner Bangkok Synthetics
Co., Ltd. held a groundbreaking ceremony for the Solution Polymerization
Styrene-Butadiene Rubber (S-SBR) plant to be constructed by their company, JSR
BST Elastomer Co., Ltd. (JBE). The Muang, Rayong Province-based plant is
scheduled to enter operation in June 2013; the facility will be the first S-SBR
manufacturing plant in Thailand.
Due to
the molecular structure of S-SBR, the substance is valued for its processability
and dynamic properties. S-SBR is utilised in fuel-efficient, high performance
tyres, and in December 2011 JSR increased S-SBR manufacturing capacity at its
Yokkaichi, Japan facility from 25,000 tons per annum to 60,000 tons. The company
also possesses an S-SBR production base in Europe through its 30,000 tons per
year capacity rights agreement with Styron Europe GmbH. The Thailand plant’s
initial capacity of 50,000 tones of year will boost JSR’s global annual capacity
to 140,000 tonnes per year. When second stage work at the plant is complete in
2015, the Thailand facility will be able to produce 100,000 tons of S-SBR per
annum.
According to JSR, its S-SBR research was
carried out with meet the conflicting priorities of low rolling resistance and
high grip in mind, and the company says the rubber it has developed reduces
friction-generated heat by 45 per cent in comparison with conventional SBR. This
was achieved by changing the ends of the rubber molecules, making it easier for
them to form connections, without changing the properties of the rubber itself.
The material properties of the rubber influence gripping power, JSR
explains.
