Silicone Heaters – Tech. Data
- Silicone Rubber Insulated Heaters ADVANTAGES Silicone heaters are suitable for applications where precise and intimate heating is required. Being thin and lightweight, silicone heater mats have a low thermal mass and hence have rapid heat up characteristics with fast response to temperature control. Silicone's wide temperature range tolerance of -60 to +230 °C and superb electrical properties give it a…
