2:1 Halogen-Free & Red Phosphorus-Free Ultra-Thin Heat Shrink TubeReturn
This halogen-free and red phosphorus-free ultra-thin heat shrink tubing is manufactured from radiation-crosslinked polyolefin material, offering superior performance with low smoke and toxicity during combustion. Ideal for high-end fire safety and environmentally sensitive applications including wire insulation, solder joint protection, mechanical shielding, and cable bundling. Widely used in modern high-tech sectors such as subway systems, high-speed trains, aircraft, and IT/digital device manufacturing.
With premium environmental ratings and complete absence of red phosphorus, it eliminates risks of phosphoric acid or phosphine generation in high-temperature/humidity conditions, ensuring maximum safety and reliability.
