General Description
S.T's thermal sheets are soft and flexible elastic thermal pad made of silicone material. They have high thermal conductivity that can easily radiate heat outside of the electronic equipments. So these are used for heat spreader in Semi-conductor, CPU, CD ROM, etc.
| Excellent thermal conductivity |
| - Easy to assembly |
| - Flame Retardant UL94V-0 |
| - RoHS compliant |
| - High resiliency & flexibility |
| - Great insulator |
