In today’s life, ptfe heat shrink tubing has been widely used in the insulation protection of various wire harnesses, solder joints, inductors, rust and corrosion prevention of metal tubes and rods. Today, let’s talk to you about what we should pay attention to in the use of ptfe heat shrink tube?

First, pay attention to the ptfe heat shrink tube selection error: ptfe heat shrink tube has different heat shrinkage multipliers, ptfe heat shrink tube specifications are generally the product of the maximum inner diameter allowed after shrinkage of the casing and shrinkage multiplier. Then we must comply with the principle of the inner diameter of the sleeve body before shrinkage, as well as the inner diameter of the sleeve object after shrinkage, when selecting the type.

Second, pay attention to ptfe heat-shrinkable tube sleeve object edge is too sharp: when we cut the tube, the cut is not flat, or grinding is not smooth will lead to ptfe heat-shrinkable tube in the use of the process of cracking.

Third, pay special attention to the ptfe heat shrink tube heating temperature is much greater than the ptfe heat shrink tube shrinkage temperature: generally we use to heat the ptfe heat shrink tube is: heat gun, lighter, oven. Heat gun is a professional tool to heat ptfe heat shrink tube, commonly used heat gun temperature can reach 400 degrees, then we use the heat gun, pay attention to the time to keep turning the heat gun, so that the ptfe heat shrink tube overall heat to ensure that the ptfe heat shrink tube shrinkage after the shape. Lighter is our convenient and commonly used tool to heat ptfe heat shrink tube, but its temperature is up to thousands of degrees, far greater than the shrinkage temperature of ptfe heat shrink tube, then we must pay attention to moving back and forth when using the lighter to make ptfe heat shrink tube overall heat evenly to prevent burning ptfe heat shrink tube at the same time will not make the shape of ptfe heat shrink tube become very ugly. The oven is also a tool to heat the ptfe heat shrink tube, the normal shrinkage temperature of ptfe heat shrink tube is 125 ± 5 °, in higher than this temperature, if the mixture of irregular ptfe heat shrink tube placed in the oven shrinkage, will probably produce mutual adhesion together, resulting in product hole, then we must pay attention to the uniform arrangement, can not be stacked together.

PTFE Heat shrinkable tube is widely used in the medical field, such as the catheter of disposable electronic endoscope. The internal structure of the catheter is covered by multiple layers, which is used in the heat shrinkable tube.
