CYG-MWT(FR) Heat Shrink Flame-retardant Medium Wall Sleeving
Category: Heat Shrink Medium Wall and Heavy Wall Sleeving
Material:
Outer: irradiation crosslinked modified polyolefin material
(Single-wall type thick-walled tube does not involve the inner layer)
Shrink ratio: 3.5: 14: 1
Features:
• Products meet UL224VW-1 flammability rating;
• 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 properties and mechanical protection properties;
• Minimum fully shrink temperature: 135 ℃.
Application:
High magnification of the polyolefin heat-shrinkable tubing material with good electrical insulation properties and mechanical protection properties, its high rate shrinkage characteristics, particularly suitable for a wide range of sizes harness connection or component connection, the thicker type of wall thickness characteristics, especially for electrical insulation protection and mechanical protection.
