The yellow and green two-color heat shrinkable tube is made of two-color co-extrusion of environmentally friendly polyolefin materials and processed by radiation modification. The product is soft, highly flame-retardant, bright and durable in color, and has stable performance. It has excellent physical, chemical and electrical properties, does not contain bromine and heavy metal substances, and meets environmental protection requirements. Widely used for marking ground wires in wire bundles or cables, as well as marking special cables and busbar ducts. The grounded wiring harness must also be standardized and must be insulated and protected with yellow and green two-color heat shrink tubes. The yellow-green heat shrinkable tube can meet the performance requirements for its markings, and can effectively protect the markings of the wrapped grounding wire harness and pipes in complex environments.
