Product Description

VANOX ZMTI Rubber Antioxidant
VANOX MTI GR
Packing:22.68KG/BAG

Description:
VANOX ZMTI is an antioxidant that is manufactured at Vanderbilt Chemicals, LLC plant in Murray, KY. It works particularly well in combination with other antioxidants. Its synergistic effect has been demonstrated with various rubber formulations using polymers such as EPDM, Natural Rubber, Neoprene, NBR and SBR.

VANOX ZMTI provides excellent protection against heat and oxygen aging, especially when combined with amine or phenolic-type antioxidants, and is also beneficial where improved flex fatigue resistance is required. The synergistic effect of VANOX ZMTI with other antioxidants has been demonstrated in both mineral- and carbon black-filled compounds, as well as with conventional sulfur, low sulfur, sulfur-donors, or peroxide cure systems.

In summary, VANOX ZMTI and VANOX MTI GR exhibit the following features:
Synergy with amines antioxidants
Maximum high temperature resistance
Flex fatigue resistance
No interference with peroxide cures
Nonvolatile
Good color

Overview:
Antioxidants are materials that protect rubber against reaction with oxygen. Just a small percentage of oxygen chemically combined with rubber can seriously degrade the physical properties of a rubber part. Heat can significantly increase the rate at which oxygen reacts with rubber; the rate approximately doubles for each 10 degree Centigrade increase in temperature. Compared to room temperature, aging a vulcanizate in a 70ºC oven provides about a 50-fold increase in reaction rate. Work in the Vanderbilt Rubber Laboratory shows that, in general, one day of oven aging at 70ºC corresponds to one year of environmental or shelf aging for natural rubber.

VANOX ZMTI Antioxidant and VANOX MTI GR Antioxidant, increase the performance of other antioxidants. The mechanism by which synergists work is not fully understood, but it may be that they are peroxide decomposers that can survive the vulcanization process.
