China liquid Silicone mold making material for concrete/artificial stone casting
Artificial Stone & Concrete Casting Silicone Rubber
1. Description
C-825/C-830/C-835 Silicone Rubber is a two-part, tin-catalyzed, liquid silicone system that cures (RTV) to a white, Shore A25-A35 rubber. This is a pourable rubber, but it can be easily thickened with Liquid Thickener or for brush-on application.
Popular product options is C-825/C-830/C-835 are the mold material of choice for high-volume veneer stone production (manual or automated manufacturing). These two-component mold rubbers capture excellent surface detail, offer exceptional dimensional stability and have unmatched lifetime and durability compared to hot melt and polypropylene systems.
Molds made from these room temperature curing systems can be completed in a much shorter timeframe (~4 hour demold) compared to latex rubber molds. When properly maintained, these molds can last for years and produce thousands of stones.
2. Technical Datasheet
Note: This is a 100A:3B mix ratio product that must be measured by weight. The choosing of suitable hardness should be according to the size and pattern design of the products. If large products and therefore multiple-piece molds are needed by customers, silicone rubber with higher hardness will be required for the molds. Conversely, soft silicon is indispensable for molds with complicated pattern and delicate details. The amount of curing agent admixture depends on the actual need of customers. More will be added for speedy drying and fast release and less when otherwise.

Silicon-carbon alloy is a new type of alloy for converter, customers choose this to, replace most of ferrosilicon, silicon carbide and recarburizer, Used in converter, smelting deoxidation alloying process
The characteristics Reduce the cost of steelmaking, increase economic, efficiency, improve product quality, stable performance, improve the quality of, molten steel, improve product performance, reduce the amount of alloy added,, reduce the cost of steel and increase economic efficiency.
Silicon carbide (SiC), also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests.
The characteristics: Reduce the cost of steelmaking, increase economic efficiency, improve product quality, stable performance, improve the quality of molten steel, improve product performance, reduce the amount of alloy added, reduce the cost of steel and increase economic efficiency.
Silicon carbon alloy instead of ferrosilicon, silicon carbide, recarburizer, reducing the amount of oxygen scavenger, a converter for deoxidizing alloy, the effect of stability, steel chemical composition, mechanical properties and internal quality are better than the traditional process.
By testing and production shows that using Si-C alloy to converter deoxy-alloy process, greatly reduce the cost of steel, creating considerable economic benefits, improve the market competitiveness of steel.
The effect of using a silicon-carbon alloy species
1, can replace ferrosilicon and carburant, FeALSi dosage is also reduced, can effectively reduce the cost of steel 6-10 yuan / ton steel
2, smelting carbon steel, special steel and some low-alloy steel, the effective recovery of effective elements.
Ferro silicon is used as an essential alloy in the production of steel and cast iron. Ferro silicon is used to remove oxygen from steel and as alloying element to improve the final quality of the steel. Ferro silicon can also be the basis for manufacture of pre-alloys like magnesium ferro silicon (fesimg), used for modification of melted malleable iron.
Main markets are the worldwide producers of alloyed, stainless and carbon steel. One of the fastest growing categories within steel is the stainless sector, in both flat and long products. Stainless steel has a specific consumption of ferro silicon 510 times higher than regular carbon steel.
Special ferro silicon grades, like low al, high purity and low c ferro silicon, are used in the production of special steel qualities. Compared to regular ferro silicon, special grades of ferro silicon will help to keep both the content of inclusions and the carbon content in the final steel at very low levels.
Ferro silicon is produced in submerged arc furnaces, using as raw material high-purity quartz, charcoal and iron ore.

Description
Crystalline silicon is a lustrous, Black-greyish color, while the Amorphous form of silicon is a dark brown powder. Making up 25% of the earth's crust, silicon metal is the second most abundant element, following oxygen. Silicon is not found freely in nature, but can form more compounds than any other element, except carbon. It is a most important to semi conducting elements. Silicon and its compounds have some of the most useful mechanical, thermal, optical, and electrical properties to mankind.
Shreeya International also cater to various Aluminium Alloy manufacturers for various grades of Silicon.
Yellow silicone ring, in simple terms, the silicone ring made of yellow color.
