S3PS Optical cable terminal positioning glue coated heat shrinkable tube
Details
| Introduction | ||||
| Cross-linked polyolefin heat shrinkable tube, coated with hot melt adhesive on the inner wall. It has good air tightness, resistance to temperature cycling, and resistance to chemical corrosion. The surface is covered with temperature-indicating paint to avoid excessive heating. It is suitable for the sealing protection of the incoming and outgoing wires of the cap-type optical cable joint box. |
