Antiozonantes

IPPD

IPPD, also known by the code 4010, acts as antioxidants and is considered the most potent class of antioxidants. It is widely used in vehicle tyres, belts and moulded and extruded rubber products. It provides long term protection to rubber compounds, its effectiveness increases as its proportion in the compound increases.

Properties

It is a high activity antidegradant for natural and synthetic elastomers, providing rubber compounds with excellent high temperature, fatigue and flexing resistance and strong antioxidant and antioxidant properties. Whilst primarily used for ozone resistance, it is a more active antioxidant than quinoline or diphenylamine-based antioxidants. The product provides compound protection against catalytic degradation by copper and other heavy metals. The product has no adverse effect on compound adhesion to textile or steel cord up to 2 phr levels. Above this concentration it can cause efflorescence and inhibit adhesion from ply to ply and ply to cord. It discolours compounds and causes severe contact and migration staining.

Uses

For use in pneumatic tyre components, solid tyres, belts, hoses, cables, automotive joints, bushings and general mechanical products exposed to continuous and intermittent dynamic operating conditions and requiring protection against ozonation.

  • Packaging: 25kg N.W./bag, in plastic fabric laminated Kraft bags lined with plastic bags.
  • Storage: Store closed containers in a cool, dry and well ventilated area. Store away from strong oxidising agents. Avoid exposure to direct sunlight. Do not double stack.

TBPA

DESCRIPTION: Antiozonant 70-TBPA is a highly effective, non-staining antiozonant for polychloroprene polymers. It can also provide good ozone protection for Nitrile/PVC blends and Natural Rubber containing at least 30% polychloroprene by weight or polychloroprene blends with SBR. Antiozonant 70- TBPA in combination with ozone protective waxes will result in non-staining properties for Natural Rubber, synthetic poly-isoprene, SBR and polybutadiene.

PHYSICAL PROPERTIES

  • Chemical Composition unsaturated acetal
  • Appearance beige to grey flakes
  • Specific Gravity1.06 Melting
  • Point approximately 194 F Storage
  • Stability Approximately 2 years at 77 F. Temperatures in excess of 104 F reduce product effectiveness. Processing has practically no effect on compound viscosity and burn time at recommended use levels.
  • Solubility insoluble in water, soluble in acetone, toluene, methylene chloride and ethanol. 
  • GENERAL RECOMMENDATIONS: The recommended levels of ozone protective wax and/or antiozonant are to achieve a burn time longer than 7 days.
