Thermal Interface Silicone Rubber
Thermal Interface Silicone Soft Pads / Ultra Soft Pads
Thermal interface silicone soft pads / ultra soft pads are made of silicone
rubber combined with thermally conductive fillers. The line-up
are single layer type and composite type. They are soft with good
adhesion, so they bonding tightly to the heat-generating unit and
the heatsink, providing more efficient cooling. |
| Main Features |
- These products are capable of close conformity to irregular or complex surfaces.
- They are easy to apply and remove, and can be used for temporary attachment.
- Nearly all products are UL-certified for flame-retardancy.
- Excellent cost performance and high thermal conductivity.
- Can be used in a wide temperature (CAS, CAB: -40 ℃ to +150 ℃, Others: -40 ℃ to +180 ℃).
|
|
| Primary Applications |
- Heat dissipation for MPUs of computers, etc.
- Heat dissipation for surface packaging microchips which generate high heat.
