5 CANCELLED: The REDUCTION of ZINC In RUBBER Compounds for A Greener Tomorrow

Tuesday, October 11, 2011: 10:45 AM
Meeting Room #17-18 (The I-X Center)
There has been and is a responsible drive to eliminate zinc oxide from industrial rubber compounds. This material, synonymous with activation of rubber cures, has many different roles to play during vulcanization and undergoes some chemical changes during this process. A stable end of cure results of zinc oxide is as zinc sulfide. The amount of zinc sulfide formed is fairly independent of actual initial zinc oxide loading and this has some interesting ramifications on zinc oxide reduction.  The use of RNPX-ZR6 trade name ZR6 a supported catalyst chemical intermediate (SCCI) manufacture by Rubber Nano Products (Pty) Ltd. of South Africa and zinc oxide reduced systems is demonstrated with a view to the environmental impact the cure package is likely to have. The conclusion is that the amount of zinc oxide destined for the environment is substantially responsibly reduced.
