2:1 Halogen-Free and Red Phosphorus-Free Heat Shrink TubeReturn
This halogen-free and red phosphorus-free heat shrink tubing is made of radiation-crosslinked polyolefin material with excellent performance characteristics. It features low smoke and toxicity when burned, making it suitable for high-end fire safety and environmentally demanding applications such as wire insulation, solder joint anti-corrosion, mechanical protection, and wire harnesses. Widely used in modern high-tech industries including subway stations, high-speed trains, aircraft, and IT/digital product manufacturing.
With high environmental standards and free from red phosphorus, it does not produce phosphoric acid or phosphine in high-temperature/high-humidity environments, ensuring superior safety and reliability.
