tpr a collagen material? The answer is yes. There are many ways to wrap the glue with TPR\TPE, and the glue-encapsulation process is very mature. As a glue-encapsulation material, TPR mainly improves the feel and comfort of plastic products, anti-slip, aesthetics, and anti-collision effects. Lien TPE manufacturer will talk about several ways of coating for your reference.
The most common coating method: secondary injection molding. TPE is bonded to plastic by injection molding. This bonding is mainly due to the hot melt adhesiveness of the TPE itself, and does not melt the two materials at the coating interface. TPE and metal coating are also adhesive. However, metal and TPE cannot be directly adhered, so the metal surface needs to be coated first, and then a layer of TPE soft material is outsourced. The coating layer on the metal surface acts as a dielectric, thereby achieving TPE and metal coating.
TPE Another way of coating: fusion. It refers to the melting bond between TPE and the coated part at the coating interface at the high temperature. It usually occurs between TPE with close polarity and compatibility and plastic parts. During injection molding and coating, TPE and plastic are at the coating interface. At the microscopic, the two materials are intertwined at the molecular chain level. At the macroscopic level, the material penetrates through melting at the interface, thereby producing excellent binding force at the coating interface.
TPE material adhesive wrapping method: embed. Sometimes the TPE and plastic or other materials are not covered with firmness, so you can make holes at the appropriate position of the covering part, and make rough, concave and concave surfaces, concave and concave grooves, etc. This increases the bonding firmness between the TPE material and the coated part.
TPE material coating method: wrap. TPE completely covers the entire surface of the plastic part (made). Since it is a whole package, there is no problem of not being able to cover it. However, for some parts with irregular surfaces and edges, it is recommended to use TPE with higher hardness to make the combination of TPE and the parts more stable. Is
tpr a collagen material? Through the above various coating mechanisms, TPE and most plastics such as PP, PC, ABS, PA, PS, PE, POM (polyformaldehyde), can be coated and coated, which provides more possibilities for innovative applications of TPE.
