PET telescopic braiding network is made of polyester monofilm by knitting machine, especially its unique braiding structure can be expanded to 1.5-2 times the size of the original diameter, which is more suitable for wrapping wires and cables, and can smoothly pass through large connectors. The product surface is smooth and the color is bright. Mainly used in computer power cord, audio and video cable, automotive interior, engine compartment, body and chassis. When a higher expansion rate is required, it is especially suitable for the protection of the automotive industry and electrical appliances. Product Characteristics: Made of strong polyester, easier to apply to irregular shapes, highly flexible, good wear resistance, halogen-free, flame retardant.
