PTFE tape, also called Teflon tape, is uneven in quality, although there are the large number of suppliers on the market. Therefore, the new industry entrants often cannot distinguish between true and false, and they often end up in the standard of measuring quality by price. Stickiness is one of the most important characteristics of the tape, so it is especially important to learn to test.
When the average customer gets the tape at their hands, their first reaction is to look at the viscosity. Unfortunately, most of their test methods are not right. For example, if a customer gets a roll of tape to hand, their first thing is to test the stickiness with his own hand, but in fact, this method is wrong.

As high temperature resistance of our tape, the viscosity is divided into initial adhesion and high temperature adhesion. The initial adhesion refers to the degree of stickiness at room temperature, and the high temperature adhesion refers to the degree of stickiness in a high temperature working environment. The visual test method of the initial adhesion is relatively simple, that is, the adhesive is applied to the adhesive, and then pulled apart. The greater the strength, the greater the viscosity. Professional specific initial adhesion data requires instrumentation to test out.

Our test method for PTFE tape is to stick it on the high temperature steel surface. This is a more formal test method, but the surface of the steel must be cleaned, the temperature range must be controlled, and professional equipment must be used to measure.

PTFE tape is not so good that it can't be based on initial adhesion, but it should be placed in a high temperature environment for observation and testing. Too strong viscosity can easily cause the glue to peel off, while too weak viscosity cannot make it permanently attached to the surface of the object. PTFE tape we produce is suitable for most customers and we promise that it does not cause any degumming.
