The market hot melt adhesive film demand for low melting point tpu hot melt adhesive film is still quite large. At present, the tpu hot melt adhesive film with a relatively low melting point is a model type hot melt reticulated film, and the melting point temperature is about 65 degrees.
For hot-melt adhesive film composite materials with such a low melting point temperature, can hot-melt adhesive be used to hot melt the hot-melt adhesive, thereby degumming the material? I believe most people will definitely say The melting point of this hot melt adhesive film is only degrees, hot boiling water will definitely be able to iron it, and the material will be degummed after being hot!
If you think so, it can only show that you really know nothing about the low melting point tpu hot melt adhesive film! Those materials that use a low-melting hot-melt adhesive film as an adhesive, even if it is scalded in 100-degree boiling water, will indeed make the hot-melt adhesive film melt again, but there is no need to worry about the phenomenon of degumming.
The main change of hot water is the shape of the hot melt adhesive film. Although it melts again, it still adheres to the material and still has good adhesion! If the product has special requirements for boiling water resistance, then it will not use low-melting hot-melt adhesive film. The use of functional hot-melt adhesive film resistant to washing and boiling water is the king!
