Halogen-free and red phosphorus-free heat shrinkable tube

Halogen-free and red phosphorus-free heat shrinkable tubing is made of radiation cross-linked polyolefin material. It has excellent performance, low smoke and low toxicity when burning. It is suitable for wire insulation, solder joint rust prevention, mechanical protection and other high-end fire safety and environmental protection requirements. Wire harnesses are widely used in modern high-tech industries such as subway stations, high-speed trains, aircraft, and IT digital product manufacturing. They have a high environmental protection level and do not contain red phosphorus. They do not produce phosphoric acid or phosphine in high temperature and high humidity environments, making them safe and reliable. It has high performance and is an upgraded product for all H-type and G-type materials. Halogen-free and red phosphorus-free heat shrinkable tubes have a higher environmental protection level and do not contain halogens and red phosphorus. Today, with increasingly stringent environmental protection requirements, halogen-free and red phosphorus-free heat shrinkable tubes will be more widely used.
