The product parameters of TMR-3 and its impact on foam performance

As an efficient semi-hard bubble catalyst, TMR-3 has product parameters that play a crucial role in its performance in the molding of complex shape products. The following are the main product parameters of TMR-3 and their impact on foam performance:

1. Chemical composition and structure

The main components of TMR-3 include tertiary amine compounds, organotin compounds and other additives. Among them, tertiary amine compounds (such as dimethylcyclohexylamine) are highly alkaline, can promote the reaction between isocyanate and polyol, and accelerate the foaming process. Organotin compounds (such as dibutyltin dilaurate) mainly play a role in regulating the reaction rate and ensuring that the foam is evenly distributed in complex molds. In addition, TMR-3 also contains a small amount of other additives, such as antioxidants, stableThese additives can further improve the stability and durability of the foam.

The activity of TMR-3 is one of its key parameters. Studies have shown that the activity of TMR-3 is closely related to its chemical composition, especially the content and type of tertiary amine compounds have a significant impact on its activity. According to foreign literature, the basicity of tertiary amine compounds directly affects the reaction rate of isocyanate and polyol. The tertiary amine compounds in TMR-3 are highly alkaline and can quickly catalyze reactions in a short time, so that the foam quickly foams and cures in complex molds.

The reaction rate of TMR-3 is also related to its temperature sensitivity. Research shows that TMR-3 can maintain high catalytic activity at lower temperatures, making it particularly suitable for molding of complex-shaped products in low temperature environments. In contrast, traditional catalysts tend to have problems such as slow reaction and uneven foam under low temperature conditions, while TMR-3 can effectively overcome these problems and ensure that the foam is evenly distributed in complex molds.

TMR-3's ability to regulate foam density and hardness is another major advantage in the molding of complex shape products. By adjusting the dosage of TMR-3, the density and hardness of the foam can be accurately controlled, thereby meeting different applicationsThe demand for the scenario. Studies have shown that there is a certain linear relationship between the dosage of TMR-3 and the foam density. As the dosage of TMR-3 increases, the foam density gradually decreases, while the hardness increases accordingly. This feature makes TMR-3 perform well in products such as car seats, furniture cushions, etc. that require both flexibility and support.

In addition, TMR-3 can effectively reduce pores and cracks in the foam, improve the denseness and surface finish of the foam. Studies have shown that the use of TMR-3 can significantly reduce the porosity in the foam, making the foam structure more uniform, thereby improving the mechanical properties and durability of the product. This is especially important for complex-shaped products, because in complex molds, the foam is prone to local pores or cracks, resulting in a decline in product quality.

Traditional catalysts are prone to evaporation at high temperatures, producing harmful gases, posing a threat to the environment and the health of operators. Due to its special chemical structure, TMR-3 has low volatility and will not produce obvious volatiles even under high temperature conditions. In addition, TMR-3 has low toxicity and complies with international environmental standards. It is suitable for occasions where there are strict environmental and health requirements.

5. Process adaptability

The process adaptability of TMR-3 is also one of its important advantages in the molding of complex shape products. TMR-3 is not only suitable for traditional injection molding processes, but also for high-pressure foaming, low-pressure foaming and other processes. Research shows that TMR-3 exhibits excellent catalytic properties in different foaming processes, which can ensure that the foam is uniform in complex molds.Distribute evenly to avoid defects such as pores and cracks. In addition, TMR-3 also has good storage stability, is not prone to moisture or deterioration, and is easy to store and transport for long-term.
