As a new material additive, the innovative application of polyurethane sponge pore agent in 3D printing materials not only provides new ideas for improving material performance, but also opens up a new path for the future development of 3D printing technology.
Polyurethane sponge pore agent is a chemical additive specially used to adjust the porosity of polyurethane foam materials. It changes the microstructure of the foam material to form a uniform open pore structure, thereby improving the material’s breathability, sound absorption, elasticity and other properties.
Polyurethane sponge pore agent has the following characteristics:
Depending on different application needs, polyurethane sponge pore opening agents can be divided into the following categories:
| Classification criteria | Type | Features |
|---|---|---|
| By chemical structure | Silicones | Efficient and stable |
| Organic fluorine | High temperature resistance and corrosion resistance | |
| By application area | Industrial grade | Applicable to mass production |
| Medical grade | Compare medical standards, non-toxic and harmless |
The selection of 3D printing materials directly affects the performance and application range of the print. Currently, commonly used 3D printing materials include plastic, metal, ceramics, etc. However, these materials have certain limitations in breathability, elasticity, sound absorption, etc., and it is difficult to meet the needs of certain special application scenarios.
Polyurethane sponge pore opening agent changes the microstructure of the 3D printing material to form a uniform pore structure, thereby improving the material’s breathability, elasticity, sound absorption and other properties. Specifically, during the material forming process, the pore agent promotes a uniform pore structure inside the material through chemical reactions or physical actions, thereby improving the performance of the material.
