However, it lacks ozone resistance and requires adding costly antiozonants in its formulations.
They are either remnants from the production process, e.g., vulcanization accelerators, or added to enhance the technical properties of the final product such as plasticizers, colors, antioxidants or antiozonants [1].
Several other antioxidants, antiozonants, and vulcanization additives were added to the compounds.
The book also discusses the use of antioxidants, antiozonants, vulcanization agents, plasticizers, and process aids for specialty elastomers.
The presence of nitrogen in the coke is the result of the thermal decomposition of additives originally used in tires, such as organic accelerators, antidegradants and antiozonants, for example sulfenamide and nitrile compounds.
The first team included Hans-Rudolf Meier (research, coating effects) and Gerrit Knobloch (application technology, plastic additives), who worked to solve the problem of the migration of antioxidants and antiozonants when used in rubber compounds.
* Antiozonants, antioxidants & light stabilizers
If the stabilizers, antiozonants. antioxidants, and other components were incorporated as they are in many elastomeric formulations, the material would not have degraded.
EPDM roofing membranes are also complex, typically containing synthetic lubber, carbon black extender oils, curing agents, antioxidants and antiozonants and small amounts of other substances for such things as reducing stickiness.
It primarily includes antioxidants and antiozonants. Antioxidants are used to protect rubber from deterring the effect of oxygen during its shelf life, whereas antiozonants are chemicals/waxes that 'bleed' to the surface of rubber articles, protecting them from ozone attack.
