Tetramethylpropanediamine (N,N,N’,N’-Tetramethyl-1,3-propanediamine, CAS No. 110-95 -2), as an important fine chemical, it is widely used in the fields of polyurethane foams, catalysts for microcellular elastomers, and curing catalysts for epoxy resins. In the domestic market, there are products from imported brands such as Solvay, as well as tetramethylpropylenediamine provided by many domestic brands such as Shandong Jinyueyuan New Materials Co., Ltd. In view of the comparative analysis of the quality of imported and domestic products, we discussed from aspects such as purity, stability, price, supply stability and regulatory compliance.
Purity and Stability
Purity is an important indicator to measure the quality of tetramethylpropylenediamine, and the content is usually required to be greater than 98%. Whether it is an imported or domestic product, the purity can meet the needs of most applications. However, high-end applications may have more stringent requirements for purity, and imported brands often have certain advantages in ultra-pure products by virtue of their mature production processes and strict quality control systems. In terms of stability, the chemical stability of tetramethylpropylenediamine is relatively good, but storage conditions have a greater impact on its stability. Imported brands usually provide more detailed storage instructions and longer shelf life commitments, which reflects their high standards in production, packaging and logistics.
Price comparison
Price is one of the key factors that determine user choice. Domestic tetramethylpropylenediamine such as Shandong Jinyueyuan New Materials Co., Ltd.’s quotation is about 40,000 yuan/ton, and the specific price will fluctuate according to market supply and demand, purchase volume and raw material costs. In contrast, the price of imported brand Solvay original products is usually higher than that of domestic products due to factors such as tariffs and transportation costs. For cost-sensitive users, domestic products offer more attractive price advantages.
Supply stability
The stability of the supply chain is an important condition for ensuring production continuity. Imported products are greatly affected by factors such as the international trade environment, exchange rate changes, and logistics efficiency, and there are certain supply risks. On the contrary, domestic suppliers of tetramethylpropylenediamine rely on localized production to respond more quickly to changes in market demand and provide more stable supply guarantees. Especially in the context of the global epidemic and increasing geopolitical uncertainty, supply chains with high localization rates are particularly important.
Regulatory Compliance
In highly regulated industries such as cosmetics and pharmaceuticals, products must comply with corresponding regulatory standards. Imported tetramethylpropylenediamine suppliers usually comply with international standards, such as REACH (European Union Registration, Evaluation, Authorization and Restriction of Chemicals), etc., which facilitates the entry of their products into the international market. Domestic products must comply with relevant Chinese national standards and regulations, such as the “Cosmetics Safety and Technical Specifications”. As China’s chemical industry standards become more closely aligned with international standards, the gap between domestic and foreign products in regulatory compliance is gradually narrowing.
Technical service and support
In terms of technical services and customer support, imported brands are usually able to provide comprehensive technical solutions, including customized services, application technical support, etc. This is due to its long-term accumulated experience and technology accumulation. Domestic companies are also constantly improving their service levels, especially in terms of localized services and rapid response to customer needs. They have obvious advantages and can better adapt to the characteristics of the Chinese market and provide customized solutions.
Conclusion
In summary, imported and domestic tetramethylpropylenediamine have their own differences in quality. Which type of product to choose depends on the specific needs of the user. . If you are pursuing ultra-high purity, stable international supply chain, and complete technical support, imported brands may be a more suitable choice. For users looking for cost-effectiveness, supply stability and localized services, domestic products show significant advantages. With the technological advancement of the domestic chemical industry and the continuous improvement of the quality management system, domestic tetramethylpropylenediamine is gradually improving its competitiveness in the global market while ensuring quality. In the future, competition between domestic and foreign products will focus more on technological innovation, environmental protection performance and comprehensive services, promoting the high-quality development of the entire industry.
