High temperature resistance:

Chemical resistance

Excellent abrasion resistance

Thanks to the special ceramic silicone rubber and aramid fiber composite material, the product can operate continuously and stably in a high temperature environment of 260℃ without deformation or performance degradation. When encountering extreme high temperatures of 300℃ for a short period of time, the thermal protection layer of the material can effectively block heat penetration and maintain the integrity of the internal structure. It is widely used in high temperature conditions such as metallurgical furnaces and aircraft engines.

The outer sheath treated with perfluorinated treatment has natural resistance to highly corrosive chemicals such as sulfuric acid and sodium hydroxide, and can resist long-term erosion by organic solvents such as gasoline and acetone. Even when immersed in complex chemical solutions, the surface of the product will not swell or crack, making it an ideal protective material for chemical pipelines and laboratory equipment.

The product adopts nano-scale tungsten carbide reinforcement technology, and its surface hardness reaches the industry-leading level, which can withstand more than one million friction tests. In high-dynamic usage scenarios such as robotic arms and automated production lines, it effectively reduces the problem of epidermal peeling caused by wear and tear, and the cable service life is increased by more than 3 times.

Expandable

Eco-friendly

The innovative memory braiding structure gives the product excellent elasticity, allowing it to stretch freely to twice its original diameter and quickly return to its original shape. This feature allows the product to be flexibly routed through pipes in a small space, while effectively buffering the tension generated by equipment vibration, reducing the risk of cable breakage, and adapting to the complex circuit layout inside precision instruments.

Environmentally friendly halogen-free flame-retardant materials are used throughout the production process. They have passed the dual international certifications of RoHS and REACH and are completely free of 10 hazardous substances such as lead and mercury. After being discarded, they can be professionally recycled and will not pollute the soil or water sources. They are particularly suitable for fields with strict environmental requirements such as food processing and medical equipment.
