Conductive Silicone Explained: Can Silicone Rubber Carry Current?
Conductive Silicone Explained .While traditional silicone is electrically insulating, Tianan’s TN3X0 series proves that with engineered carbon loading, silicone rubber can deliver consistent and tunable conductivity. This makes it essential in sectors such as automotive electronics, keypads, and antistatic shielding.
Engineering Principle
Conductive silicone is a composite — combining silicone polymer with conductive media such as carbon black. This allows the material to offer:
- Shore A hardness from 40 to 70
- Volume resistivity as low as 5 Ω·cm
- Tear strength up to 12 kN/m
TN3X0 Grades & Electrical Performance
| Grade | Hardness | Resistivity | Color |
|---|---|---|---|
| TN-340 | 40 Shore A | 15 Ω·cm | Black solid |
| TN-350 | 50 Shore A | 12 Ω·cm | Black solid |
| TN-360 | 60 Shore A | 10 Ω·cm | Black solid |
| TN-370 | 70 Shore A | 5 Ω·cm | Black solid |
Industrial Use Cases
- Switch contact domes
- Electrically conductive seals
- Injection molded anti-static enclosures
