High-density fiber optic heat shrink tubing anti-marking in stock
High-density fiber-reinforced heat shrink tubing with anti-marking properties is available for immediate shipment, offering superior tensile strength, environmental protection, and customizable specifications.
Product Overview
High-density fiber optic heat shrink tubing is designed to protect and reinforce optical fiber splices while maintaining optical transmission performance. These tubes typically feature a cross-linked polyolefin outer layer, a hot melt inner tube, and a stainless steel or aramid-reinforced core, providing mechanical strength and preventing fiber damage during installation . The anti-marking design ensures that the tubing remains clean and intact, even under repeated handling or environmental stress.
Key Features
