The polar nature of silica prevents the excessive blooming of the antiozonant
, and thus the appearance of the sidewall remains good.
One chemically different antiozonant
in the investigation was a substituted triazine, specifically 2,4,6-tris-(N-1,4-dimethylpentyl-p phenylenediamino)-l,3,5-triazine sold under the tradename of Durozone 37.
LANXESSs Vulkanox antioxidants and Vulkazon antiozonants
significantly extend the lifespan of elastomers.
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.
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.
The business is a leading global supplier of a comprehensive portfolio of additives including antioxidants, antiozonants
, intermediates and inhibitors, polymer modifiers, and UV stabilizers used by customers to improve the production and performance properties of polymers, rubbers and plastics.
Protectants: Protectants include antioxidants that slow deterioration caused by contact with oxygen, antiozonants
that slow deterioration caused by contact with ozone, and waxes, as well as metal deactivators and flame-retardants.
RubberChem 2010, the seventh international conference devoted to rubber chemicals, compounding and mixing covered developments in a range of rubber chemicals from accelerators, antioxidants and antiozonants
to retarders and peptisers.
Materials covered include antioxidants, antiozonants
, accelerators, waxes, adhesion promoters and other products (retarders/antiscorch agents, antireversion agents, curing agents, tackifiers, peptizers, foaming and blowing agents and flame retardants).
