N,N’-Ethylenebis(stearamide), with the CAS number 110-30-5, is a widely used chemical product. It appears as a white to off - white powder or granule. The molecular formula of N,N’-Ethylenebis(stearamide) is C₃₈H₇₆N₂O₂, and its molecular weight is approximately 593.02 g/mol. This product is typically produced through a chemical reaction between stearic acid and ethylene diamine.
It has a high melting point, usually in the range of 140 - 146°C, which gives it good thermal stability. It is insoluble in water but soluble in some organic solvents such as hot xylene, toluene, and chloroform. In terms of quality, our factory - supplied product meets strict industry standards, with a high purity level, which ensures its excellent performance in various applications.
1. **Plastic Industry**: N,N’-Ethylenebis(stearamide) is widely used as a lubricant and release agent in the plastic processing industry. It can reduce the friction between the plastic melt and the processing equipment, improving the flowability of the plastic during injection molding, extrusion, and calendering processes. This results in better surface finish of the plastic products, reduces the occurrence of defects such as melt fractures, and also prolongs the service life of the processing equipment.
2. **Rubber Industry**: In the rubber industry, it acts as a dispersing agent and release agent. It helps to evenly disperse various additives in the rubber compound, improving the mechanical properties of the rubber products. It also makes it easier to remove the rubber products from the molds, reducing the adhesion between the rubber and the mold surface.
3. **Coating Industry**: It is used as an anti - caking agent and matting agent in the coating industry. It can prevent the agglomeration of pigments and fillers in the coating, ensuring the uniformity of the coating. At the same time, it can provide a certain degree of matting effect, making the coating surface have a more delicate and high - end appearance.
When using N,N’-Ethylenebis(stearamide), it should be added at the appropriate stage of the production process. In the plastic industry, it can be added directly to the plastic raw materials before melting. The recommended dosage is usually 0.1% - 1% of the total mass of the plastic, depending on the specific plastic type and processing requirements. For example, in polyolefin plastics, a relatively lower dosage may be sufficient, while in engineering plastics with higher processing requirements, a slightly higher dosage may be needed.
In the rubber industry, it is often added during the mixing process of the rubber compound. It should be well - dispersed in the rubber matrix to fully发挥 its functions. In the coating industry, it can be added during the grinding or mixing process of the coating, and the dosage is adjusted according to the desired anti - caking and matting effects.
**Case 1: Plastic Injection Molding**
A plastic injection molding company was facing problems with poor surface finish and high friction during the production of automotive interior plastic parts. After using our N,N’-Ethylenebis(stearamide) at a dosage of 0.3% of the plastic raw material, the flowability of the plastic melt improved significantly. The surface of the molded parts became smoother, and the rejection rate due to surface defects decreased from 8% to less than 2%. This not only improved the product quality but also increased the production efficiency.
**Case 2: Rubber Tire Production**
A tire manufacturing company was experiencing difficulties in releasing the tires from the molds and uneven dispersion of additives in the rubber compound. By adding our product at a dosage of 0.5% during the mixing process, the rubber compound became more uniform, and the tires could be easily removed from the molds without any damage. The mechanical properties of the tires, such as tensile strength and tear resistance, also showed a certain degree of improvement.
