Manufacturer Good Price Polyetheramine T403 CAS:9046-10-0
Polyetheramine T403 is a class of polyolefin compounds with a soft polyether backbone, capped by primary or secondary amine groups. Because the main chain of the molecule is a soft polyether chain, and the hydrogen on the terminal of polyether amine is more active than the hydrogen on the terminal hydroxyl group of polyether, therefore, Polyetheramine can be a good substitute for polyether in some material processes, and can improve the application performance of new materials. Polyetheramine are widely used in polyurethane reactive injection molding materials, polyurea spraying, epoxy resin curing agents and gasoline scavengers.

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 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.
