How TPU hot melt adhesive film manufacturers can improve product performance
Adhesive film adhesion is poor.
In the process of applying TPU hot melt adhesive film to composite materials, it is necessary to heat the film to a certain temperature in order to give full play to its adhesiveness. If the composite temperature is not up to standard, it is easy to affect the overall bonding effect. Generally speaking, the contact area of the entire roller surface of the old roller laminating machine is relatively large, and the heat dissipation speed is relatively fast, so it is easy to cause the lamination temperature to fail to meet the standard in the subsequent lamination. For this type of problem, equipment temperatures above the melting point of typical thin films are required.

TPU hot melt adhesive film manufacturers will improve product performance in the following ways during the production of films.
add lubricant
Appropriate addition of lubricants in the production process of TPU hot melt adhesive film can improve the release performance of the film during heating and plastic molding, and make the final film surface smoother. It should be noted that the amount of lubricant added should not be too much, otherwise it will affect the viscosity of the entire film. Common additives such as paraffin and synthetic waxes.
Add colorant
In the production of TPU hot melt adhesive film, the purpose of adding colorant is to change the color of the finished film. Different companies have certain requirements for the viscosity and aesthetics of the entire film when purchasing the film. About 80% of plastic products are colored.
Add filler
TPU hot melt adhesive film manufacturers add an appropriate amount of fillers during the production of the film, the purpose is to reduce the shrinkage and viscosity of the entire film, increase its gap filling, and also reduce the production cost of the entire product. The amount of filler added should be appropriate, adding too much will affect its fluidity and adhesion.
