The safety regulations of home appliances and industrial heating equipment in various countries continue to tighten, promoting the PTC heater industry to accelerate the upgrading of safety technology, and the industry concentration is gradually increasing. In view of potential safety hazards such as dry burning and overheating that may occur during the use of PTC heaters, relevant standards clearly require multiple protective devices to promote enterprises to increase investment in safety technology research and development.

At present, mainstream enterprises in the industry have generally adopted multiple safety technologies such as double insulation design, anti-dry burning protection, and overheating fuse, and some high-end products have also integrated temperature monitoring sensors to achieve rapid power off under abnormal working conditions. The implementation of new safety standards has raised the entry threshold of the industry, and some small and medium-sized enterprises with insufficient technical reserves and backward production processes have been gradually eliminated, and the market share of enterprises with core technology and large-scale production capacity has continued to increase. In the context of fluctuating raw material costs, leading enterprises reduce costs through large-scale procurement and modular production, and at the same time transform to high-end products with technological advantages to further consolidate their competitive advantages. In the future, safety performance and energy efficiency will become the core competitiveness of PTC heater companies, promoting the transformation of the industry to high-quality development.
