White carbon black
1.improve the tensile strength of rubber
2.good reinforcing performance
3.high wear resistance
1.Introduction:
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.
2.Application:
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.
3.Features:
1) Good activity and the absorption rate.
2) High reinforcing effect and chemical stability.
3) Porous surface area.
4) Good dispersibility.

- Q: No one knows the expression of the catalyst and the chemical expression of the acridine
- In organic reactions, the catalyst is complex and consists of several or more. Write Chinese characters directly.
- Q: Which branch of chemistry or what specialty can study the catalyst
- Analytical Chemistry: Application of Catalysts in Analytical Chemistry, Component Analysis of Certain Natural and Synthetic Catalysts
- Q: I dont know what it is but when i open up my computer it comes up and it says that its not working? so i really dont know what to do.
- Catalyst is what ATI calls the drivers for their video cards or video devices built into mainboards. Download the newest video driver for your video card from ATI or from your computer manufacturer's site if the video device came with the computer. Install that, and you should be all set. You may want to check your add and remove programs and remove any of the old, malfunctioning ATI or Catalyst drivers before attempting to install the new one. Good luck!
- Q: Can a catalyst react with a reactant?
- Exactly no. A catalyst just provides a shortcut to a reaction and thats is by combining with the reactant and at end of reaction it splits from the reactant it combined with.if a catalyst reacts then it is not a catalyst
- Q: The greater the chemical adsorption strength, the catalyst activity changes
- If the adsorbent is a reactant, then the better the adsorption capacity of the better catalytic effect; but the catalyst surface of the product will generally have adsorption, if this effect has become very strong, then desorption The process will become difficult, the catalytic effect will decline; the other one, if the adsorption of other substances, such as the reaction may produce a reaction or the catalyst will poison the material, it is greatly detrimental to the catalytic effect. The effect is to be controlled in a suitable optimum range for superior, and preferably to be selectively adsorbed.
- Q: Can manganese dioxide be used as a catalyst for various chemical reactions?
- Manganese dioxide can be a catalyst for hydrogen peroxide decomposition, a catalyst for the preparation of chlorine gas from potassium chlorate, and the like can be reactants
- Q: What is the difference between biological and chemical catalysts?
- Biological catalysis involves an enzyme usually working in conjunction with a co-enzyme. These enzyme/co-enzyme systems are highly specific and are usually only effective for one reaction. Catalysis of non biological reactions is usually much more general and any one catalyst will be effective in many reactions.
- Q: hey people i need your help about my science lab report...the question on my paper says "what function the catalyst?....please help me on this one...i would really appreciate if you leave me answers....much mahalos to all you folkss...thanks
- lowers the activation energy of a reaction so it happens at a faster rate
- Q: If the college entrance examination questions related to whether the catalyst involved in the reaction, how should I answer. (We must college entrance examination, I hope you help out, thank you.)
- The catalyst is involved in the reaction in the chemical reaction. Because it participates in the chemical reaction, it can change the course of the reaction, reduce the activation energy, increase the reaction rate, and the quality and chemical properties before and after the reaction. I hope to help you;
- Q: Why would the Eact decrease if a catalyst is added?
- A catalyst by its very nature increases the rate of reaction by binding to a reactant, hence changing its shape and reactivity with other reactants. However, the catalyst is neither consumed nor will it change the chemical shape of the products.
