Far Infrared Heating Cable

1. Raw material costs Carbon fiber quality: The quality of carbon fiber is one of the key factors determining its price. High quality carbon fiber has higher strength, better conductivity, and thermal stability. The heating wires produced by well-known carbon fiber brands are relatively expensive because these carbon fibers perform well in terms of raw material purity, uniformity of fiber bundles, etc., ensuring excellent and stable performance of the heating wires.    Auxiliary materials: In addition to the carbon fiber body, auxiliary materials such as insulation layer and sheath of the heating wire will also affect the price. High quality insulation materials, such as fluoroplastics (PTFE), polyvinyl chloride (PVC), etc., have good electrical insulation, high temperature resistance, and corrosion resistance, which can improve the safety and service life of heating wires, but the cost is also high. For example, the price of carbon fiber heating wires using high-performance fluoroplastics as insulation layers will be higher than that of ordinary PVC insulated heating wires.   2. Production process Manufacturing accuracy: High precision manufacturing processes can ensure consistent performance of carbon fiber heating wires. For example, in the winding and weaving process of carbon fiber filaments, if the technology is advanced and the precision is high, it can make the resistance of the heating wire uniform and the heating efficiency stable. By adopting advanced automated production equipment and precise manufacturing processes, the price of the produced heating wire will correspondingly increase, as these processes can effectively reduce the rate of defective products and improve product quality.   The complexity of the production process: If the production process involves special processing steps, such as surface modification of carbon fibers, manufacturing of multi-layer composite structures, etc., it will increase production costs and thus affect prices. For example, carbon fiber heating wires that have undergone special surface treatment can enhance the bonding strength between carbon fiber and other materials, improve the overall performance of the heating wire, but this additional treatment process will increase the price. 3. Power and specifications Power size: Generally speaking, carbon fiber heating wires with higher power have relatively higher prices. This is because high-power heating wires require the use of more carbon fiber materials, and in the design and manufacturing process, many factors such as heat dissipation and safety need to be considered, resulting in higher requirements for technology and materials. For example, high-power carbon fiber heating wires used for industrial heating (such as those with a power of over 1000W) are more expensive than ordinary household heating wires with lower power (such as 100-500W).   Length and wire diameter specifications: Carbon fiber heating wires with different length and wire diameter specifications have different prices. A longer heating wire naturally has a higher price, while a thicker wire diameter usually means higher heating efficiency and carrying capacity, and the price will correspondingly increase. For example, a carbon fiber heating wire with a diameter of 6mm will be more expensive than a similar heating wire with a diameter of 3mm.   4. Application areas and market demand Market supply and demand relationship: When the demand for far infrared heating cable in the market exceeds the supply, prices often rise; On the contrary, prices may decrease. For example, during the peak season of winter heating demand, the market demand for carbon fiber underfloor heating lines increases significantly. If the supply is relatively tight, the price will rise. In some off-season or emerging application areas where market demand has not yet fully opened up, prices may remain relatively stable or decrease to stimulate market demand.
