1. Introduction

Polyurethane materials are widely used in automobiles, construction, furniture, electronics and other fields due to their excellent physical properties and chemical stability. The polyurethane casting process is one of the important methods for producing polyurethane products, and the optimization of its process parameters has an important impact on product quality and production efficiency. As a new catalyst, the thermosensitive catalyst SA-1 has shown significant advantages in the polyurethane casting process. This article will introduce the characteristics, applications and their optimization effects on the polyurethane casting process in detail.

2. Overview of polyurethane casting process

The polyurethane casting process is the process of injecting liquid polyurethane raw materials into the mold through a casting machine and curing and forming after chemical reactions. This process mainly includes the following steps:

Raw material preparation: Mix raw materials such as polyether polyol, isocyanate, catalyst, foaming agent, etc. in proportion.
Casting: Inject the mixed raw materials into the mold through a casting machine.
Currect: The raw materials undergo chemical reaction in the mold to form solid polyurethane products.
Discharge: After curing is completed, remove the product from the mold.

The key to the polyurethane casting process is to control the reaction rate and curing time to ensure the quality and production efficiency of the product.

3. Introduction to the Thermal Sensitive Catalyst SA-1

Thermal-sensitive catalyst SA-1 is a new type of polyurethane reaction catalyst with the following characteristics:

Thermal Sensitivity: SA-1 is less active at room temperature, and its catalytic activity is significantly enhanced as the temperature increases.
High efficiency: SA-1 can significantly accelerate the polyurethane reaction and shorten the curing time.
Environmentality: SA-1 does not contain heavy metals and harmful substances, and meets environmental protection requirements.

4. SA-1 isApplication in polyurethane casting process

The application of SA-1 in the polyurethane casting process is mainly reflected in the following aspects:

Reaction rate control: The thermally sensitive characteristics of SA-1 enable it to automatically adjust the reaction rate according to temperature changes during the pouring process, avoiding excessive or slow reaction.
Currecting time optimization: SA-1 can significantly shorten the curing time of polyurethane and improve production efficiency.
Product quality improvement: The use of SA-1 can reduce bubbles and defects in the product, and improve the physical properties and appearance quality of the product.

6.3 Product quality improvement

The use of SA-1 can reduce bubbles and defects in the product and improve the physical properties and appearance quality of the product. The following table compares the quality indicators of polyurethane products before and after the use of SA-1:

Quality Index	Traditional catalyst	SA-1
Number of bubbles	10-15 pieces/cm²	2-5 pieces/cm²
Tension Strength (MPa)	20-25	25-30
Elongation of Break (%)	200-250	250-300

7. Practical application case analysis

7.1 Car seat production

In car seat production, the polyurethane casting process is one of the key links. After using SA-1, the curing time of the seat was shortened from the original 12 minutes to 7 minutes, and the production efficiency was increased by 40%. At the same time, the physical performance and appearance quality of the seats have also been significantly improved, with the number of bubbles reduced by 60%, and the tensile strength increased by 20%.

7.2 Building insulation material production

In the production of building insulation materials, the optimization of polyurethane casting process has an important impact on product quality and production efficiency. After using SA-1, the curing time of the insulation material was shortened from the original 15 minutes to 8 minutes, and the production efficiency was increased by 47%. At the same time, the thermal conductivity of the insulation material has been reduced by 10%, and the insulation performance has been significantly improved.
