Polyurethane foaming catalyst LED-103: An effective method to improve the smoothness and aesthetics of polyurethane products
Introduction
Polyurethane (PU) is a polymer material widely used in the fields of construction, automobile, furniture, shoe materials, etc. Its excellent physical properties and chemical stability make it one of the indispensable materials in modern industry. However, the surface smoothness and aesthetics of polyurethane products have always been a key issue that needs to be solved in the production process. This article will introduce a new polyurethane foaming catalyst, LED-103, in detail, and explore its effective methods in improving the smoothness and aesthetics of the surface of polyurethane products.
1. Overview of polyurethane foaming catalyst
1.1 Basic principles of polyurethane foaming
Polyurethane foaming is a process in which isocyanate reacts with polyols to form polyurethane, and at the same time releases carbon dioxide gas to form a foam structure. During foaming, the action of the catalyst is crucial, it can regulate the reaction rate and control the density and structure of the foam.
1.2 Function of catalyst
Catalytics mainly play the following roles in the polyurethane foaming process:
- Adjust the reaction rate: Control the reaction rate of isocyanate and polyol to avoid too fast or too slow reaction.
- Control foam structure: affects the size and distribution of the foam, thereby affecting the physical properties of the product.
- Improving the surface quality of the product: By optimizing reaction conditions, reducing surface defects, improving smoothness and aesthetics.
1.3 Limitations of traditional catalysts
Traditional polyurethane foaming catalysts such as amine and organotin catalysts have good performance in terms of reaction rate and foam structure control, but have certain limitations in terms of product surface smoothness and aesthetics. Specifically manifested as:
- Rough surface: The foam pore size is uneven, resulting in rough surface.
- Ununiform color: The residue of the catalyst or the incomplete reaction leads to the uneven color of the product.
- Odor problem: Some catalysts will produce irritating odors during the reaction, affecting the user experience.
