Polymer Thermistor Market Size, Share & Growth Forecast 2025

Global Polymer Thermistor Market size was valued at US$ 734 million in 2024 and is projected to reach US$ 967 million by 2032, at a CAGR of 3.5% during the forecast period 2025-2032.

Polymer thermistors are temperature-sensitive resistors made from polymer composites filled with conductive particles like carbon black. These components exhibit a positive temperature coefficient (PTC), meaning their resistance increases dramatically when a specific temperature threshold is reached. This unique property makes them ideal for overcurrent protection and temperature sensing applications across industries.

The market growth is driven by expanding applications in consumer electronics, automotive systems, and industrial equipment where reliable circuit protection is critical. While North America currently holds the largest market share (32% in 2024), Asia-Pacific is expected to witness the fastest growth due to booming electronics manufacturing in China and India. Leading manufacturers including TDK Electronics, Murata, and Vishay are investing in advanced formulations to improve thermal response times and operating temperature ranges.
