Manufacturer Good Price Methylene Chloride CAS:75-09-2
Methylene Chloride is a compound generated by two hydrogen atoms in methane molecules, and molecular CH2CL2.Methylene Chloride is colorless, transparent, heavier, and volatile liquid. It has a smell and sweetness similar to ether. It does not burn. Methylene Chloride is slightly soluble in water, and it dissolves with most commonly used organic solvents. It can also be dissolved in any proportion with other chlorine-containing solvents, ether, ethanol, and N-di metamimamamide. Methylene Chloride is difficult to dissolve in liquid ammonia at room temperature, which can be quickly dissolved in phenol, aldehyde, ketone, triathrin, tororine, cycamine, acetylcetate. The phase Chemicalbook is 1.3266 (20/4 ° C). The melting point -95.1 ° C. Boiling point 40 ° C. Fully low -boiling point solvents are often used to replace flammable petroleum ether, ether, etc., and can be used as local anesthesia, refrigerant and fire extinguishing agent. The spontaneous combustion point is 640 ° C. Decoction (20 ° C) 0.43MPa · s. The refractive index nd (20 ° C) 1.4244. Critical temperature is 237 ° C, and critical pressure is 6.0795MPa. HCL and traces of light are generated after thermal solution, and the water is heated for a long time to generate formaldehyde and HCL. Further chloride, CHCL3 and CCL4 can be obtained.

Manufacturer Good Price N-VINYL PYRROLIDONE (NVP) CAS 88-12-0
N-VINYL PYRROLIDONE (N-Vinyl-2-pyrrolidone) is referred to as NVP, also known as 1-vinyl-2-pyrrolidone, N-VINYL PYRROLIDONE. N-VINYL PYRROLIDONE is a colorless or light yellow transparent liquid with slight odor at room temperature, easily soluble in Chemicalbook water and other organic solvents. Because N-vinylpyrrolidone can increase various physical and chemical properties of products.N-VINYL PYRROLIDONE is widely used: in radiation medicine, wood floor industry, paper or cardboard industry, packaging materials, screen ink industry, the use of NVP improves the physical properties of products.
N-VINYL PYRROLIDONE (NVP) is commonly used as a reactive diluent for radiation curing in UV-coating, UV-inks, and UV adhesives. It is used as a monomer to produce water soluble polyvinylpyrrolidone (PVP) with uses in pharmaceuticals, oil field, cosmetics, food additives & adhesives. It is used in the manufacture of copolymers with, for example, acrylic acid, acrylates, vinyl acetate and acrylonitrile and in the synthesis of phenolic resins.

Manufacturer Good Price P-TOLUENESULFONYLISOCYANATE (PTSI) CAS 4083-64-1
P-TOLUENESULFONYLISOCYANATE (PTSI) is a single functional isocyanate. P-TOLUENESULFONYLISOCYANATE (PTSI) has high activity and can react with conventional diisocyanates, such as TDI and HDI, with water in polyols and solvents. The resulting carbamate does not increase the viscosity of the system. The disadvantage is that the toxicity of oxazolidine and other dehydrants is large; P-TOLUENESULFONYLISOCYANATE (PTSI) reacts with water to produce carbon dioxide and toluenesulfamide, so P-TOLUENESULFONYLISOCYANATE (PTSI) cannot be used directly in paint formulations and is generally used for pre-dehydration. To remove 1g of water in the solvent, about 12g of PTSI is theoretically required, but the actual amount should be higher than this.

Manufacturer Good Price CalciumAlumina Cement CAS:65997-16-2
CalciumAlumina Cement is cement with calcium calcium or calcium aluminum as its main mineral component. It is made of natural aluminum or industrial alumina and calcium carbonate (limestone) according to a certain proportion, which is made by burning or electric melt.
Ingredients and categories: CalciumAlumina Cement can be divided into ordinary aluminum calcium calcium cement (al2O3 53-72%, CAO 21-35%) and pure aluminum calcium cement (al2O3 72-82%, CAO 19-23 %) Two categories. Ordinary aluminum cement cement can be divided into low -iron type (FE2O3 <2%) and high -speed rail type (Fe2O37-16%). Low -rail -type aluminum -type calcium cement can be divided into alum soil cement (Al2O353 ~ 56 %, CAO 33-35%), aluminum -60 cement (al2O359%to 61%, CAO 27-31%), and low -calcium aluminum acid cement (Al2O3 65-70%, CAO 21 to 24%). Pure aluminum calcium cement can be divided into two types: Al2O3 72-78%) and ultra -high aluminum type (Al2O3 78-85%). In addition, there are fast and hard early strong aluminum calcium cement.CAS: 65997-16-2
