• MIL-DTL-23053/5 Class 1 and 3 Heat-Shrinking Tubes Heat-Shrinking polyolefin tubes in DYMO are designed to provide a permanent solution for both cable identification and protection. The tubes can be printed directly with any DYMO industrial labeling tool and do not disappear when exposed to solvents, fuels, or oils. The printed sleeve is installed before the connection and fully secured when the heat gun is used to shrink the sleeve after the connection.
• Features and benefits: Thermal shrinkage of 3:1 (tube shrinks to 1/3 of original diameter when heated) Polyolefin material - commonly used insulation, flexible and durable Print content without fading or blurring Even in contact with abrasives, cleaning solvents or industrial liquids Print content is legible Flame retardant Shipping length: 1.5 m
• What does a thermal shrinkage ratio of 3:1 mean?
• With a shrinkage ratio of 3:1, tube heating shrinks to 1/3 of its original diameter. The original tube is three times the size of the shrunken tube.
• Please tell me how to shrink the tube.
• A heat gun or heat shrink oven is the best way to shrink tubes. Be sure to know the correct heating temperature of the tube before heating.　Remember to check all health and safety precautions before using the heating device.
