What is the reason why TPE plug material and wire are not tightly bonded

Why are some TPE wires not firmly bonded to the plug? TPE wire and plug are usually bonded by wrapping adhesive. If the wrapping adhesive is not firm, the bonding between wire and plug will not be firm. Therefore, the source of the problem starts from the encapsulation. The difference between wire and plug material is the main reason why the encapsulation is not firm, which is the compatibility problem of the encapsulation materials we often say. Compatibility of materials generally refers to the ability of the components of a blend to accommodate each other to form a uniform material. The compatibility between different polymers is different. Some materials have excellent compatibility, but some materials have almost no compatibility. Let's give a simple example.
If your wire is made of TPE material and the plug is made of PVC material, the formula components of TPE material and PVC material are polar, and the adhesive will easily fall off. If you choose TPE wire and TPE plug, the same material has the same polarity, and the wrapping adhesive will be firm and will not fall off. However, there is another point that needs to be paid attention to. When selecting the same material, the formula of the material should also be taken into consideration. The composition and structure of different formulas of the same material will also lead to the phenomenon that the coating is not firm and falls off. Therefore, Xiaobian suggests that you must choose the same material with the same formula when wrapping the wire and plug. If you cannot do this, you must also choose two materials with similar polarities!
