1. Introduction

Polyurethane foaming materials are widely used in construction, automobile, furniture, packaging and other fields, and their performance directly affects the quality of the final product. In the polyurethane foaming process, the choice of catalyst is crucial. It not only affects the foaming speed, but also determines the opening time of the material, curing time and the physical properties of the final product. This article will introduce in detail the unique advantages and practical effects of the polyurethane foaming catalyst LED-103 in extending its opening time.

2. Overview of polyurethane foaming catalyst

Polyurethane foaming catalyst is an indispensable additive in the polyurethane foaming process. Its main function is to accelerate the reaction between isocyanate and polyol, thereby controlling the foaming speed, curing time and the performance of the final product. Common polyurethane foaming catalysts include amine catalysts, metal organic compound catalysts, etc.

2.1 Amines Catalyst

Amine catalysts are one of the commonly used catalysts in the foaming process of polyurethane. Their main features are fast reaction speed and high catalytic efficiency. However, amine catalysts also have some disadvantages, such as a large odor and a great impact on the environment.

2.2 Metal Organic Compound Catalyst

Metal organic compound catalysts are another commonly used polyurethane foaming catalysts. Their main features are high catalytic efficiency and fast reaction speed. However, metal organic compound catalysts also have some disadvantages, such as high prices and a greater impact on the environment.

3. Basic characteristics of LED-103 catalyst

LED-103 is a new type of polyurethane foaming catalyst. Its main feature is that it can significantly extend the opening time of polyurethane foaming materials while maintaining high catalytic efficiency. The basic characteristics of LED-103 catalyst are as follows:

3.1 Chemical structure

The chemical structure of the LED-103 catalyst is a special amine compound, and its molecular structure contains multiple active groups, which can react efficiently with isocyanate and polyol.

3.2 Physical Properties

The LED-103 catalyst is a colorless or light yellow liquid with low volatility and high stability. Its density is 1.05 g/cm³ and its boiling point is 200℃.

3.3 Catalytic efficiency

The LED-103 catalyst has high catalytic efficiency and can achieve efficient catalysis at a lower usage amount. Its catalytic efficiency is 1.5 times that of traditional amine catalysts.

4. The unique advantages of LED-103 in extending opening hours

Opening time refers to the time from mixing to starting curing of polyurethane foaming materials, which is an important factor affecting the processing performance of foaming materials. LED-103 catalysts have the following unique advantages in extending opening hours:

4.1 Extend opening hours

The LED-103 catalyst can significantly extend the opening time of the polyurethane foaming material, so that it can maintain fluidity for a longer period of time after mixing, thereby providing more time windows for processing. Experiments show that the opening time of polyurethane foamed materials using LED-103 catalyst can be extended to twice that of conventional catalysts.

4.2 Maintain high catalytic efficiency

Although the LED-103 catalyst can significantly extend the opening time, its catalytic efficiency has not been reduced. Experiments show that the polyurethane foaming materials using LED-103 catalyst can maintain high catalytic efficiency while extending the opening time, ensuring that the foaming materials have good physical properties after curing.

4.3 Improve processing performance

Because the LED-103 catalyst can extend the opening time, the polyurethane foaming material can better adapt to complex mold shapes during processing, reduce the generation of bubbles and defects, thereby improving the quality of the final product.

4.4 Reduce processing costs

Extending opening time can not only improve processing performance, but also reduce processing costs. Since LED-103 catalysts can extend the opening time, the waste of materials can be reduced during processing and production costs can be reduced.
