How to choose the right TPU hot melt adhesive film

There are several factors to consider when selecting the right hot melt adhesive film to ensure it meets the needs of a particular application.

First and foremost, understanding the type of material used in the hot melt adhesive film is key. Common hot-melt adhesive films are polyester type, polyethylene type and polyurethane type, etc., and different materials have different adhesive properties, temperature resistance and chemical resistance. For example, polyurethane-type hot-melt adhesive films generally have high flexibility and impact resistance, making them suitable for use in applications where elasticity is required.

Secondly, it is necessary to choose the corresponding bond strength according to the application. If the adhesive film needs to be used in a high-load or high-pressure environment, it is wise to choose a hot melt adhesive film with high bond strength. At the same time, it is important to consider the opening time and curing time of the adhesive film to ensure that there is sufficient operating time during processing.

In addition, different application scenarios have different requirements for temperature and water resistance. For applications that are exposed to high temperatures or humidity, a hot-melt adhesive film that is resistant to high temperatures and water is more suitable.

Finally, it is advisable to conduct a small range of experiments in the actual application to ensure that the selected hot melt adhesive film can meet the actual needs. In addition, it is also a good option to communicate with suppliers to get professional advice and samples. This can be experimentally verified to ensure that the selected hot melt adhesive film performs well in a wide range of conditions.
