Purity: The purity of T-9 is as high as over 99%, which is one of its core indicators as a catalyst. High purity ensures that no impurities are introduced during chemical reactions, thereby improving reaction selectivity and efficiency. For example, in the polyurethane foaming process, high-purity T-9 can significantly reduce the generation of by-products, making the foam more uniform and dense.
Density: The density is between 1.20-1.30 g/cm³. This parameter is very important for storage and transportation. Accurate density data helps engineers accurately calculate the required addition amount when designing reaction systems, while avoiding waste or shortages caused by volume errors.
Refractive index: The refractive index is in the range of 1.48-1.50. This value reflects the optical properties of the T-9 molecular structure. Although refractive index itself does not directly affect catalytic performance, it can be used to quickly detect product consistency, especially during quality control.
Boiling point: The boiling point of T-9 exceeds 250°C, which makes it stable under high temperature conditions and not easy to volatilize or decompose. This feature is particularly important for industrial scenarios that require high-temperature processing, such as polyurethane spraying or high-temperature curing coatings.
Viscosity: At 25°C, the viscosity of T-9 is 50-100 mPa·s. This parameter directly affects its fluidity and convenience of processing operations. The lower viscosity makes it easier to mix with other raw materials, thereby increasing production efficiency.
Acid value: The acid value is less than or equal to 1.0 mg KOH/g. This indicator characterizes the content of acidic impurities in T-9. Too high an acid value may cause side reactions and affect the catalytic effect. Therefore, low acid value is an important guarantee for ensuring the efficient catalytic performance of T-9.
Tin content: The tin content is between 18-20%. This parameter directly reflects the proportion of active ingredients in T-9. High tin content means higher catalytic activity and lower unit costs.
Moisture content: Moisture content is less than or equal to 0.1%. This indicator is crucial to prevent hydrolysis reactions. T-9 is prone to hydrolysis in humid environments, thereby reducing its catalytic performance. Therefore, strict control of moisture content is key to ensuring its long-term stability.
