The PTC COMPOSITE products produced by Legines are widely used in high-tech fields such as intelligent heating, temperature control, and circuit protection, providing customers with safe, stable, and energy-saving solutions.

In the context of the widespread application of automated manufacturing, air brake systems, and precision accessories, PTC composite materials are gradually becoming one of the key technical materials. PTC Composite is a functional material made of a variety of materials. Its core feature is that as the temperature rises, its resistance value will also increase, thus playing a role in automatic current limiting and overheating protection. Thanks to this self-regulating characteristic, PTC composites have been widely used in many industries, including automobiles, home appliances, industrial equipment, electrical protection systems, etc.

PTC composites can be used as thermal protection elements. After the temperature rises to the set value, its resistance rises rapidly, thereby limiting the flow of current, preventing the circuit from overheating or even causing a fire. This feature makes it an indispensable protection mechanism in high-safety electrical equipment (such as air brake systems).
PTC composites can be used as thermistors. PTC materials provide precise temperature monitoring and control in refrigeration, heating or light source equipment. For example, in air conditioning systems, refrigerators or lighting equipment, PTC can automatically sense temperature changes and adjust the system operation status to achieve efficient energy consumption management.
PTC composites can be used in heating pads, hair dryers, defoggers and other equipment to form a self-limiting temperature heating system. Its working principle is: when the temperature rises, the resistance increases, the current is automatically reduced to avoid overheating, which not only improves safety, but also extends the service life of the equipment. It is very suitable for industrial or household equipment with high-frequency startup and long-term operation. PTC composite materials can also be used in PFC circuits to improve the power factor of motors, lighting systems or power supply equipment, improve the efficiency of electric energy utilization, reduce energy loss, and help enterprises achieve more efficient power management.
PTC materials can be used for current overload protection. In abnormal conditions such as short circuits or current mutations, PTC materials can respond quickly, increase resistance values, automatically cut off or limit current, prevent damage to the electrical system, and improve system stability and safety. This feature is particularly suitable for air brake systems to enhance the reliability of the overall system.

As the development trend of automation and intelligence accelerates, PTC composite materials are widely used in many key industries with their excellent self-temperature regulation, overcurrent protection and thermal stability. Legines Industrial Machinery Inc. is constantly expanding the application scenarios of PTC Composite products in various industries with its precision manufacturing strength and material technology accumulation.

In the process of electrification and intelligence of modern automobiles, PTC Composite materials play a vital role. PTC Composite materials can be used in battery management systems to achieve battery overheating protection and temperature balance, and improve battery life and safety. PTC Composite materials can also be used in seat heaters and steering wheel heaters. By using their self-limiting temperature characteristics, they provide stable, comfortable and energy-saving in-vehicle heating solutions. In addition, PTC Composite materials can also be used in the air brake system control circuit of modern automobiles, which can effectively prevent the air circuit electronic control system from being damaged due to abnormal current and ensure the safety of vehicle operation. Legines' air brake hose assembly and PTC components can achieve system-level integration and enhance the intelligent control capabilities of the entire vehicle pipeline.

PTC Composite materials are also widely used in the consumer electronics industry. They can be used in laptops and mobile phone chargers to prevent equipment damage or fire caused by abnormal current; they can be used in LED drive power supplies and small appliances to automatically limit current at high temperatures to ensure the long-term stability of the power module. In addition, the compact structure and self-regulating characteristics of PTC Composite materials make them particularly suitable for the multiple requirements of modern electronic products for safety, volume and energy efficiency.

PTC Composite materials can also be used in industrial equipment and deeply integrated with Legines precision parts systems. In industrial manufacturing and control systems, PTC Composite is a key component to achieve system protection and energy optimization. In CNC machine tool control systems, PTC thermistors are used to protect circuit boards, cables and key control modules to prevent thermal runaway. In cable heating and environmental temperature control systems, they can provide safe and automated heating control in harsh environments. They can also achieve motor protection and power management, providing dual protection against overload and overheating for high-power industrial motors, extending the service life of equipment.
