Ho Chi Minh City, 05 June 2012, Bridgestone Vietnam Ltd. announces Bridgestone Japan Corporation has successfully synthesized high-cis polyisoprene rubber (IR) from Isoprene provided by Ajinomoto company - partners in the development of synthetic rubber for tires.
Tire demand to increase with the growth of industry production cars worldwide due to pay for the environmental protection and the development of social, Bridgestone Corporation, Japan is committed to first pioneer in the development of technology to use renewable resources capable and reused in the manufacture of tires.
Bridgestone Japan Corporation introduced many inventions to create "100% sustainable materials" products until 2050, and IR is derived from crude oil is which a limited resource. Bridgestone Corporation has studied the methods of raw production from renewable material resources to ensure the sustainable supply. With the advanced technology, IR has been successfully synthesized from isoprene (derived biomass) by Ajinomoto. This development is a key factor to achieve sustainable social development of the Bridgestone Corporation. Since IR can replace natural rubber, Bridgestone Corporation wants to develop IR into one of the most diverse materials for tires.
Through efforts in the study of applied biomaterials in natural rubber and synthetic rubber, Bridgestone Japan Corporation is taking steps to develop "100% raw sustainability" (re-create and re-use material resource).
*1 The bonding of two or more monomers to form a compound with large molecular weight, or the reaction. For example, polyisoprene is created through an isoprene and polymer reaction.
*2 Synthetic rubber (IR) created through a chemical reaction with isoprene
*3 A synthetic rubber (IR) raw material; a highly volatile and colorless liquid at room temperature.
*4 Materials that do not use resources such as fossil fuels that cannot be consumed indefinitely and are expected to be depleted.
*5 Chemicals effective in hastening polyisoprene reactions
