Our films are designed to offer energy-efficient and safe heating solutions for industries like automotive, floor heating, and consumer electronics. With advanced PTC heating technology, we ensure reliable, self-regulating performance in all our products.
What is PTC Heating Film?
PTC (Positive Temperature Coefficient) heating films are smart, self-regulating heating elements. As the temperature rises, their resistance increases, which reduces current flow and naturally limits the heat. This makes PTC heaters incredibly safe, energy-efficient, and reliable.
Unlike traditional resistive heaters, PTC films do not require external controllers. Once they reach a set temperature — known as the Curie temperature — they stabilize automatically. Our PTC heating films typically regulate at 50°C, making them ideal for temperature-sensitive applications.

Our technology improves patient comfort and accelerates recovery, particularly in medical environments that require consistent temperature control and long-lasting heating.
Wearable Technology
Our PTC heating films offer efficient heating solutions for wearable products, including heated ski mats, heated gloves, and heated vests. Whether skiing in cold winter conditions or for everyday warmth, PTC heating films provide even, long-lasting heat to ensure comfort and warmth for wearers.
Home and Pet Heating
In home and pet heating applications, PTC heating films are used in underfloor heating systems, providing energy-efficient warmth for homes. Additionally, for pet heating pads requiring stable and safe temperatures, our products provide comfortable heating mats for pets, ensuring a cozy and safe environment, especially during colder months.
PTC Heating Film for Home and Pet Heating Applications
PTC heating film is widely used in home and pet heating applications where safety, temperature stability, and long-term reliability are critical.
Thanks to its self-regulating temperature characteristics, PTC heating film can automatically limit surface temperature, significantly reducing the risk of overheating and hot spots compared to traditional heating elements.
In pet heating pads, PTC heating film provides gentle, evenly distributed warmth that helps maintain a comfortable resting temperature for pets without causing burns or thermal stress. This makes it an ideal heating solution for cats, dogs, and other small animals that require continuous, low-wattage heating.
For home and pet heating systems, PTC heating film is commonly integrated into floor warming pads, pet bedding, and localized heating zones. Its stable performance, thin structure, and energy efficiency allow manufacturers to design safer and more durable heating products for both residential and pet care environments.
