Understanding Conductive Silicone
Chemical Composition and Structure
Conductive silicone is a hybrid material that combines the elasticity and resilience of silicone with the electrical conductivity of various fillers. The primary components include:
- Silicone Base. This is the foundation of the material, known for its flexibility, durability, and resistance to extreme temperatures and environmental factors.
- Conductive Fillers. Materials such as carbon black, silver, and copper are incorporated into the silicone base to impart electrical conductivity. These fillers create pathways within the silicone matrix, allowing electrical current to pass through.
This unique structure results from the dispersion of these fillers within the silicone base. The quality of dispersion and the type of filler used determine the level of conductivity and the overall performance of the material.
