Optical fiber connection box heat shrinkable tube

Optical fiber connection box heat shrink tube   The thick wall adopts a composite structure of "semi-hard insulating polyolefin (PE) outer layer + hot melt adhesive (EVA or PA) inner layer", which can provide excellent mechanical protection for the connection between the optical cable splice box and the cable, effectively resisting external force impact, vibration and other environmental influences. The inner layer hot melt adhesive adopts either a spiral or direct coating process, both of which have the functions of bonding and waterproof sealing. Compared with the direct coating type, the spiral coating type has no risk of slippage during construction, and has better air retention and sealing performance. Its high shrinkage rate performance can closely adhere to irregular interfaces and large-sized connection parts, achieving a more reliable protective effect.   Characteristics and Advantages   1.Shrinkage ratio: 3:1, UV-resistant   2. Efficient electronic insulation protection and…
