Non silicon thermal conductive silicone grease

Curly foam absorbing material is a kind of porous material prepared by a specific process. Its foam structure presents a curly geometric shape, such as "egg shaped" or other irregular shapes. This design aims to enhance the material's absorption of electromagnetic waves. Materials are typically composed of conductive or magnetic fillers and polymer matrices.

characteristic

1. High wave absorption performance: crimp foam wave absorption material has high electromagnetic wave absorption performance due to its unique crimp structure. These structures can effectively capture and absorb electromagnetic waves, reducing reflections.
2. Lightweight and flexible: because of its foam structure, the crimped foam wave absorbing material is very light and has good flexibility, which is easy to install on various complex surfaces.
3. Broadband absorption: Materials are capable of absorbing electromagnetic waves over a wide frequency range, making them suitable for various application scenarios.
4. Strong environmental adaptability: crimp foam absorbing material can maintain stability under various temperature and humidity conditions.
5. Cost effectiveness: Compared with some high-performance absorbing materials, crimp foam absorbing materials have lower cost and good economic benefits.

Material composition

1. Matrix materials: Common matrix materials include polymer matrices such as polyurethane (PU), polyethylene (PE), polypropylene (PP), etc.
2. Absorbing fillers: including but not limited to metal powders (such as nickel powder, iron powder), carbon nanotubes (CNTs), graphene, carbon black, and other conductive or magnetic materials.

Preparation process

1. Mixing and dispersion: Fully mix and evenly disperse the matrix material with conductive or magnetic fillers.
2. Foaming: The mixture is formed into porous foam structure through chemical or physical foaming process.
3. Molding: Forming the foamed material into the desired curled structure through specific processes such as extrusion, molding, etc.
4. Post treatment: further heat treatment or other surface treatment shall be carried out on the molded crimp foam wave absorbing material to optimize its physical performance and electromagnetic wave absorption performance.
