RS Pro Clear Flexible Polyolefin Heat Shrink Tubing, 2：1 Ratio
From RS Pro a range of high quality, easy to use heat shrink tubingmAde from flexible, transparent polyolefin
This clear heat shrink tubing allowsmArker tags and identificationmArks on cables and wires to be viewed through the tubing after it has been applied
The shrink ratio of this clear heat shrink tubing is 2：1 which means it shrinks to half of its original diameter and is SAE-AMS-DTL-23053 approved
What is Heat Shrink Tubing?
Heat shrink tubing is a type of extruded plastic tubing that can be cut to size and fitted over a wire or cable joint to protect and insulate the connection
When heated is applied the tubing shrinks permanently providing a protective seal
The amount it shrinks depends on its shrink ratio
When you buy the tubing it is in its expanded state, this expanded tubing has memory so when it is heated it returns to its original state
Larger shrink ratios are required to covermAterials with a greater size variation
Features and Benefits of Flexible Polyolefin Heat Shrink Tubing
Flexible Polyolefin is amAterial derived from polyethylene and is one of the most commonly used insulatingmAterials being both highly flexible, fast shrinking and durable
When heated this polyolefin tubing shrinks radially to half its original diameter hence the ratio of 2：1
Flexible Polyolefin tubing has the following properties：
Very flexible 2：1 shrinkage ratio, shrinks to half its original diameter Operating temperature range of -55 to +135°C Shrink temperature of 110°C minimum Excellent electrical insulation properties Resistant to common fluids and solvents Excellent abrasion resistance SAE-AMS-DTL-23053/5 Class 2 approved
What is Polyolefin Heat Shrink Tubing Used For?
This polyolefin heat-shrinkable tubing is very versatile and is used in military and aerospace applications, industrialmAchinery, electronics and constructionmAchinery
Heat shrink tubing is used for protecting and sealing cable joints and in-line components such as disconnect terminals and wire splices
It can also be used to carry out repairs on existing worn or torn cable or wiring insulation
Applications include the following：
Electrical insulation and protection of resistors and capacitors Environmental protection against moisture, dust, and chemicals
Mechanical protection to wires and small parts from abrasion Mechanical strain relief on cable and connector joints to prevent damage caused by flexing or bending Bundling and organizing harness wires, cable, and tubing
How to use Heat Shrink Tubing
The diameter of the wire or cable is measured and the correct sized heat shrink tubing selected
A piece of the tube is cut to size which is long enough to cover the connection or joint after heating
This then slides onto the wire
After the cable or wire has been joined the piece of heat shrink shrinkable tube is moved over the joint and heated with a heat gun until it shrinks and forms a tight wrapping around the joint.
