Product Description:

Precipitated Silica
1.Used in tires, tire body, with beam layer and sidewall rubber and rubber products,Shoes Etc.

2.Product Status:White powder

Suggest for Use:

(1) M160 Used in tires, tire body, with beam layer and sidewall rubber and rubber products.For strengthening filler in rubber, rubber formula provides high hardness, high breaking strength, high tear strength and high wear resistance, improve the rubber and steel cord bonding strength. Improve the durability of the rubber, to improve flexible and shock resistance, resistance to improve tractional snow tires on the road, improve the tire all-weather performance.

(2) M170 Used in tires, rubber products and sole material.For strengthening filler in rubber, rubber formula provides high hardness, high breaking strength, high tear strength and high wear resistance, and resistance to aging performance.

(3) M180 Used in shoe materials, rubber products. For strengthening filler in rubber, in color rubber products, instead of reinforcing carbon black, meet the needs of white or translucent product, it has strong bonding strength, tear resistance and heat-resistant anti-aging performance.

Q:Explain how catalysts help to reduce costs in industrial processes !?Thanks
Catalysts are efficient at converting starting materials to the final products. Since catalysts convert these materials to the product faster, less energy will be used, and often less other materials will be used to complete the process. Both will save the company save time and money. Not to mention the catalyst can be reused, often hundreds of times before it needs to be replaced. Hope that helps!
Q:Is palladium predominantly a catalyst in chemistry?
Palladium in the chemical mainly to do the catalyst; palladium and ruthenium, iridium, silver, gold, copper and other alloy, can improve the palladium resistivity, hardness and strength, used in the manufacture of precision resistors, jewelry and so on.
Q:Can you describe at least 4 ways a catalyst can lower the activation energy of a reaction?
To see how a catalyst accelerates the reaction, we need to look at the potential energy diagram shown below which compares the non-catalytic and the catalytic reaction. For the non-catalytic reaction, the figure is simply the familiar way to visualize the Arrhenius equation: the reaction proceeds when A and B collide with succificient energy to overcome the activation barrier. The change in Gibbs free energy between reactants, A + B, and the product P is delta G. The catalytic reaction starts by bonding of the reactants A and B to the catalyst, in a spontaneous reaction. Hence, the formation of this complex is exothermic and the free energy is lowered. There then follows the reaction between A and B while they are bound to the catalyst. This step is associated with an activation energy; however, it is significantly lower than that for the uncatalyzed reaction. Finally, the product P seperates from the catalyst in an endothermic step. The energy diagram illustrates 4 ways the catalyst works : The catalyst offers an alternative path for the reaction that is energetically more favorable The activation energy of the catalytic reaction is significantly smaller than that of the uncatalyzed reaction; hence the rate of the catalytic reaction is much larger The overall change in free energy for the catalytic reaction equals that of the uncatalyzed reaction. Hence, the catalyst does not affect the equilibrium constant for the overall reaction. A catalyst cannot change the thermodynamics of a reaction but it can change the kinetics. The catalyst accelerates both the forward and the reverse reaction to the same extent. In other words, if a catalyst accelerates the formation of product P from A and B, it will do the same for the decomposition of P into A and B.
Q:Also, how is the catalyst affected by heat? Please answer all of the questions not just one of the three. THANK YOU!
It denatures the catalyst because the rise in pH or amount of H3O+ ions. Temperature will also denature the catalyst if it's out of its optimum range.
Q:What is chemical adsorption and its relationship with heterogeneous catalysis
The catalytic cycle includes five steps: diffusion, chemical adsorption, surface reaction, desorption and reverse diffusion.The chemical adsorption is an important part of the heterogeneous catalysis process, and the adsorption of the reactants on the catalyst surface,
Q:Can manganese dioxide do any catalyst for chemical reactions?
The catalyst is involved in the reaction during the reaction and is reduced to the original composition after the reaction is completed. For example: heating decomposition of potassium permanganate when adding potassium permanganate. Potassium permanganate decomposition process, potassium permanganate is involved in the reaction, the specific way is not clear. And finally appeared with potassium permanganate. Reaction before and after the catalyst morphology changes, particles become powder, powder particles and so on.
Q:and what type of macromolecule are they made of? thanks!
A catalyst is any substance that speeds up a chemical reaction without otherwise changing the outcome of the reaction. Catalysts do this by lowering a reaction's activation energy (which is the energy barrier that must be overcome before the reaction can proceed spontaneously). Catalysts are not permanently changed by the reactions they catalyze, so one catalyst could reasonably catalyze the same reaction many times over. Enzymes are biological catalysts because they lower the activation energy of metabolic reactions (and therefore increase their rate). Every enzyme has an active site that is specific for a particular substrate, or for a small related group of substrates. When the correct substrate binds to the active site, the enzyme catalyzes a particular reaction and releases new products. Substrates that don't match the shape of the enzyme's active site usually won't be affected by the enzyme. Enzymes are proteins, which are in turn polymers of amino acids. The sequence of amino acids in an enzyme, as well as the three-dimensional structure of the polypeptide chain, are essential for determining the enzyme's functionality. I hope that helps. Good luck!
Q:Manganese dioxide can be used as a catalyst for various chemical reactions
MnO2 + 4HCl = heating = MnCl2 + Cl2 + 2HCl
Q:Chemistry GCSE what is a catalyst?
A catalyst is something that makes a chemical reaction happen faster. An example is when manganese oxide (MnO2) is added to hydrogen peroxide (H2O2), and the hydrogen peroxide starts to break up into water and oxygen. Catalysts are either of natural or synthetic origin. They are useful because they leave no residue in the solution they have sped up. A catalyst also can also be used in a reaction again and again. Catalysts work by lowering the activation energy of a reaction. This allows less energy to be used, thus speeding up the reaction. The opposite of a catalyst is an inhibitor, which slow down reactions
