Chemical Structure

Specification:

ITEMS	Data
Appearance	Dark purple granules
Heating Loss %≤	0.5
Ash Content %≤	0.3
Assay %≥	95.0
Freezing Point ℃≥	44.0

Properties:

Blackish brown solid(Specific gravity:1.1), soluble in gasoline, benzene, acetone and etc, insoluble in water. It will become black in exposure to air, but there is no effect on its properties. Due to low melting point, it should be stored away from high temperature.

Application:

An antioxidant used for rubber products withhigh efficiency, low psison and low solvent-extraction amunt, also used as stabilizer in synthetic rubber, which is widely applied in many kinds of rubber products.

Package:

25kg N.W./bag, in plastic fabric laminated kraft bags lined with plastic bags.

Storage:

Do not store the product in bulk above 50/122°,F for prolonged perod of time, to avoid oxidation and loss of ativity. Use a nitrogen blanket when bulk storage time at maximum temperature will be greater than one month. In sealed drums the product has excellent storage stability at storage temperatures below 35/95°, F. Storage area should be dry and protected from excessive heat and excessive exposure to air, to prevent degradation. Keep partially used containers closed. Shelf life is dependant of temperature of storage and extent of exposure to air.
