  • Can IPPD be disposed of sludge from rubber production?
  • There may be disposal of IPPD to land from rubber production; this should be as controlled waste. The octanol-water partition coefficient indicates that adsorption to sludge should occur, although the majority of the chemical would be hydrolysed.
  • How much IPPD is added to rubber in tyre production?
  • IPPD is added to rubber in tyre production at a level of 1-2%. Conversion of the compounded material into the rubber article, in this case tyres. As this is a closed process losses are considered to be minimal; the UCD suggests a value of 0.01%. Again this will be assumed to go to water. These figures give a production.
  • Is IPPD toxicity to soil dwelling organisms?
  • There is no information on toxicity to soil dwelling organisms for the hydrolysis products of IPPD, although this is not expected to be a principle exposure route. The rapid hydrolysis of IPPD must be considered when reviewing the available aquatic test results.
  • What is the melting point of rubber?
  • The British Rubber Manufacturers Association (1990) quotes a melting point of 73°C. These values are consistent with variation in manufacture and purity. The boiling point has been quoted at 220°C at 1.33 kPa (Bayer AG) and at 161°C at 0.133 kPa (Monsanto). The density (specific gravity) has been quoted as 1.01-1.07 at 25°C (Monsanto, MSDS).
