Properties: White powder. The density is 1.24. Soluble in carbon sulfide. benzene, chloroform, insoluble in water. Good storage stability.

Application: Used for primary or secondary ultra-accelerator in NR. IR, BR, SBR, NBR, HR. EPDM, and their latexes. Similar in property to PZ and EZ. less accelerating effects than PZ and EZ to dry rubber. Effectively used in both natural and synthetic latexes for faster curing at normal (low) temperature than with PZ and EZ, and less scorching and blooming

Packaging: 25kg plastic woven bag, paper with plastic film bag, Kraft paper bag, or jumbo bag.

Storage: The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The validity is 2year.

Note: The product could be ultra fine powder based on customer accurate requirement.

Q:What is the direction of the chemistry of the material chemistry?
Generally in the chemical plant to do engineering design engineers, the past few years, science and engineering graduates generally do not worry about work.
Q:Please help - question about catalysts !?
they reduce the activation energy of a specific chemical reaction, which in turn reduces the temperature at which a reaction will occur at any significant rate (and therefore fuel costs) while generally making the reaction occur faster. In general, if you can catalyze a reaction, you can get away with using less robust equipment because you don't need as much energy.
Q:Catalyst by laurie halse anderson?
yea is an extremely solid e book yet very tragic. there have been no longer any sesquipedalian words( clever and long ) and you are able to desire to get words u mite no longer understand wid counsel from contxt clues. have enjoyable!!
Q:What is the chemical catalyst for CAT12
(Cat1, cat2, cat4 and cat5) in the presence of terephthalic acid,
Q:What chemical reactions can water do the catalyst?
Many solid and solid reactions can be converted into reactions between liquids, which speeds up the reaction rate, and perhaps the water here is the catalyst.
Q:What is the meaning of catalyst in chemistry?
In the chemical reaction can change the reaction rate of chemical reaction (increase or decrease) without changing the chemical balance, and its own quality and chemical properties in the chemical reaction before and after the material did not change the catalyst.
Q:Before and after the reaction, the chemical properties and quality of the water did not change, and the water was the catalyst
Dry aluminum powder and iodine does not react, there is water to react.
Q:What is the reaction in chemistry?
Industrial production of ammonia, ethanol, industrial synthesis of ammonia, ethanol catalytic oxidation, acetaldehyde oxidation into acetic acid, ethyl acetate preparation, the transformation of automobile exhaust, benzene substitution reaction and addition reaction, some other addition reaction of hydrocarbons, Ethanol dehydration to produce ethylene and so on
Q:What is a catalyst?
The catalyst can change the reaction rate (either fast or slow), but the catalyst itself is not affected before and after the reaction, that is, the quality of the same, the chemical nature of the same, itself has not changed.
Q:What is the microcosmic principle of the catalytic reaction in the chemical reaction?
It is actually directly involved in the reaction, but, after the reaction, it has become a product out, the equivalent of no response
