Description

RSY round Heat Shrink Tube to seal dome type fiber optic splice closure-FOSC

Customized length & size available

Tianyi RSY round heat shrink tube is a medium wall, heat-shrinkable polyolefin tubing with large expansion ratios and an inner liner of hot melt adhesive. Tianyi RSY heat shrink tube provides good electrical insulation and, at the same time, resists abrasion and corrosion. The material is tough and provides good mechanical support and strain relief. Typical applications include covering of splices and electrical terminations. RSY heat shrink tube provides seals with a variety of synthetic sheath materials and most metals, including lead, aluminum and steel.

Material:
• Outer: irradiation cross-linked modified polyolefin material
• Inner layer: hot melt adhesive
• Single-wall type thick-walled tube does not involve the inner layer

Shrink ratio: 3.5: 1 or 4: 1
Features:
• High shrink ratio, the greater the diameter of the quilt was coverage;
• Black sleeving, has excellent UV resistance;
• Semi-rigid walled polyolefin material has excellent electrical insulation propertiesand mechanical protection properties;
• Minimum fully shrink temperature: 135 ℃.
Application:
High rate of heat-shrinkable tubing of polyolefin material with good electrical insulation properties and mechanical protection properties, the high rate shrinkagecharacteristics for a wide range of sizes harness connection or component connection, internal corrosion sealant make it particularly suitable for corrosion protection of metal pipe connections.
