Non silicon thermal conductive sheet

1. Ingredient PreparationSelect liquid acrylic rubber and other silicone free resins as substrates, and add thermal conductive powders (such as alumina, boron nitride, etc.) and additives (such as vulcanizing agents, antioxidants, etc.).

2. mix and stirAdd the raw materials to the mixer according to the formula ratio, and perform vacuum kneading and stirring to ensure that all components are evenly mixed.

3. vulcanization moldingPut the mixed rubber material into the mold and perform hot pressing vulcanization under vacuum conditions to solidify the material into shape.

4. post-processingAfter cooling and cutting the vulcanized thermal conductive sheet, obtain non silicon thermal conductive sheets that meet the size and performance requirements.
   

Production principle:

1. Silicon free substrate thermal conductivityUsing non silicone resin (such as liquid acrylic rubber) as the substrate, heat is transferred through the vibration and collision of its molecular chains to achieve the thermal conductivity function of the substrate itself.
2. High thermal conductivity filler reinforcementAdding fillers with high thermal conductivity (such as alumina and boron nitride) forms a thermal conductivity network through direct contact between filler particles, significantly improving overall thermal conductivity efficiency.
3. Optimization of interface thermal resistanceBy modifying the interface between the filler and the substrate, the interface thermal resistance is reduced, promoting efficient heat transfer between the filler and the substrate.
4. Dense structure designThrough vulcanization molding process, a dense three-dimensional network structure is formed to reduce voids and defects, ensuring the continuity and stability of the heat transfer path.
5. No silicone oil precipitation guaranteeThe substrate does not contain silicone oil components, fundamentally avoiding pollution and performance degradation caused by silicone oil precipitation under high temperature or long-term use.
