Product Description:


White carbon black
1.improve the tensile strength of rubber
2.good reinforcing performance
3.high wear resistance


White Carbon Black(Precipitated silica) with special physic-chemical properties, work as reinforcing transparent fillers highly valued in formulation of rubber-based blends. They lead to enhanced tensile strength, tear strength and abrasion resistance and increase hardness of vulcanized rubbers. On the other hand, They reduce consumption of rubbers and therefore reduce the cost.


It is widely used in silicon rubber, constrction sealant, coating, rubber, shoes, medicine, resin processing, printing ink and other industries.
1) Silicon Rubber: Improves silicon rubbers durability, rebound rate, and anti-distortion performance.
2) Plastics Industry: Improves plastic s tenacity, strength and prevents water absorption.
3) Coating Industry: Prevents agglomeration and drip. Thixotropic  additives. Increase denseness and smoothness of paint.
4) Medicine Industry: Increase denseness ,floating , carrying function in medicine. It also can be used as the pesticide powder and anti-agglomeration.


1) Good activity and the absorption rate.
2) High reinforcing effect and chemical stability.
3) Porous surface area.
4) Good dispersibility.

Q:Chemical catalyst system baa?
Catalyst is divided into inorganic catalyst and organic catalyst organic reaction generally need more catalyst, such as concentrated sulfuric acid
Q:MnO2: catalyst?
A catalyst changes the RATE of a reaction, not the products. So, yes, you get the same products without the catalyst as you do with the catalyst.
Q:Why are there so many catalysts?
Many important chemical reactions require inputs of energy to proceed. If a catalyst is present less energy will be required to complete the reaction. Catalysts are substances that are mixed in with materials that are to be reacted, but they themselves do not, in the end, change chemically. They establish a local environment that promotes one or more chemical reactions to take place. A catalyst is important in many industrial processes. Sulfuric acid, which is used to produce batteries, detergents, dyes, explosives, plastics, and many other produces, is commonly produced using a catalyst called vanadium oxide. Ammonia, a primary component of many fertilizers, could not be produced economically without the use of iron oxide which speed up the reaction. The process of catalyst also affects the state of our global environment. Automobiles use catalytic converters to treat exhaust. The metals platinum and palladium facilitate the chemical conversion of noxious gases to more inert forms, greatly decreasing the environmental impact of combustion engines. Probably the most important impact of catalyst is on life itself. All important biochemical reactions are catalyzed by molecules called enzymes. Most enzymes are proteins which catalyze specific reactions within cells. Some examples include polymerases, which synthesize DNS and RNA, peptidases, which digest protein, and ATP synthases, which produce energy for the many different cell activities.
Q:Catalyst by laurie halse anderson?
no but aOMG i laurie halse anderson! OMG I LOVED HER BOOK FEVER 1793 wooooooooooo that book was aweomse. you should read it
Q:What is the principle of catalyst reaction rate in chemical reactions?
Can significantly change the reaction rate and its own chemical properties and quantity in the reaction before and after the basic material unchanged. The catalyst has a positive catalyst (i.e., accelerates the reaction rate) and a negative catalyst (i.e., reduces the reaction rate), and generally does not specifically refer to both the positive catalyst.
Q:How does catalyst aid a chemical reaction?
Catalyst just speed up the chemical reaction they don't effect the chemical reaction or its equilibrium.............
Q:Why are transition metals more likely to be catalysts?
activation energy has got nothing to do with this. the main reason that the transition metal oxides are catalysts is that they have vacant d orbitals. the reagents are adsorbed on the metal surface and the d orbitals serve as a sort of clamp between the substrates and reagents. for example if you consider the hydrogenation of ethylene in palladium catalyst here the d orbitals lead to syn addition of hydrogen by clamping the pi electron cloud . this is a sort of chemisorption.
Q:What is a catalyst/catalase? help?
Catalysts and catalase are two different things, and the definitions that you listed are correct. A catalyst is something that speeds up the rate of a chemical reaction. Many chemical reactions occur naturally and do not require any energy, but they occur so slowly that they are not useful, and catalysts can be used in cases like this to speed up the process. For example iron metal exposed to oxygen and water turns to rust, but if you need a lot of rust by tomorrow, leaving a chunk of iron out in the rain is not a practical solution because it will take too long to convert all that iron metal into rust.
Q:What are the properties of the catalyst (eg, specificity)?
The composition, chemical properties and quality of the catalyst itself do not change before and after the reaction; its relationship with the reaction system is as highly selective (or specific) as the relationship between the lock and the key. A catalyst is not for all Chemical reactions are catalyzed, for example, manganese dioxide in the thermal decomposition of potassium chlorate in the catalytic role to speed up the chemical reaction rate, but other chemical reactions do not necessarily have a catalytic effect.Some chemical reaction is not only a single catalyst, such as potassium chlorate Thermal decomposition can play a catalytic role in the magnesium oxide, iron oxide and copper oxide and so on.
Q:describe a biological catalyst?
A biological catalyst is the almighty enzyme. An enzyme takes the food that animals eat, yes including you, and breaks the raw stuff into more tangible byte sizes pieces for all the cells of a living organism. So essentially a catalysts is a mover of a biological system. Whole systems such as the apex predator the great bald eagle. I think the whole system catalyst are the decomposer organisms. The little crawlers like shredders and mushrooms. I hope that this helps
