Silicone Rubber Heating Pad with a built-in thermistor provides stable 120V heating, fast response, and precise temperature control for industrial and medical equipment.
The Silicone Rubber Heating Pad delivers stable surface heat at 120V with fast thermal response and strong mechanical durability. The thin structure, flexible body, and bonded thermistor sensor provide precise temperature feedback, ideal for equipment that needs controlled and uniform heating.
Danyu Electronics fabricates each pad with premium silicone rubber, etched-foil or wire-wound circuits, and a high-accuracy NTC thermistor to support closed-loop temperature regulation.

Danyu Electronics supplies custom Silicone Rubber Heating Pads with integrated thermistors for OEM and industrial projects. We support engineering teams from concept to mass production.
Why customers choose us:
The thermistor provides real-time temperature feedback so your controller can regulate heat output precisely and keep the system stable during continuous use.
2. Can I request a custom size or special shape?
Yes. Danyu Electronics supports custom lengths, round pads, contour shapes, hole patterns, and multi-zone designs. Maximum size is typically 600 × 1000 mm.
3. What temperature can the heater reach?
Standard silicone heaters operate up to 250°C continuous and up to 280°C short-term, depending on watt density and installation conditions.
4. What thermistor models are available?
We offer NTC 10K (default), NTC 50K, NTC 100K, PT100, PT1000, and fixed-temperature thermal fuses for additional protection.
5. Can the heater work on curved surfaces?
Yes. The silicone rubber body is flexible and conforms to curved or irregular surfaces without cracking.
6. How do I mount the heater to my device?
You may select high-temperature PSA (3M adhesive), silicone RTV glue, mechanical fasteners, or integrated mounting tabs.
7. Does the heater support 120V only?
The listed model is for 120V, but voltage can be customized from 12V to 480V for different applications.
From concept design to mass production. Reliable supply chain, stable quality.
