Which Hot-Melt Adhesive Film Should Be Used For the Heating Film?

To understand which hot-melt adhesive film and omentum are more suitable in the field of heating sheets, we must first understand the material composition to be bonded.

If you intend to use it on the inner layer of the heating sheet, if your bonding needs are: PET film with graphene or conductors and conventional PET film, then it is recommended that you choose the model TJS125 PES hot melt adhesive film and The model is TWS105 PES hot melt adhesive mesh. Because the main component of the PES film and the omentum is copolyester, and the component (polyester) of the PET film has similarities in the molecular formula, so the adhesion between them will be very good. In the field of heating film, PI film is also used instead of PET film. At this time, the hot melt adhesive film of SWA120 and the hot melt adhesive film of XJA110 are also a good choice, because the composition of PI film is polyimide, and The main component of SWA120 and XJA110 is copolyamide, and there are similarities in the molecular formula.

Tip: In the bonding of the inner layer of the heating sheet, many friends are worried that the adhesive film will affect the conductivity of the product, and our test shows that no matter what kind of hot melt adhesive film will not affect this aspect, there is no need to worry too much.

And if your requirement is to be used on the outside of the heating film, when PET film (PI film) is bonded with textile fabrics or leather and other materials, then our standard for choosing hot melt adhesive film and omentum is to choose those that can be glued. The product model that can hold the PET film (or PI film) and stick to the outer material.

For example, when you plan to bond PET film and fabric, you can choose HJU120 with TJS125, TWS105, and TPU components; and if the fabric is PP non-woven fabric, then you must choose HJV85 film with EVA and LWV65 mesh. Because the melting point of PP material is low, other high-temperature adhesive films are not suitable; if it is PET film and leather bonding, it is necessary to choose SWA120 omentum and XJA110 film, because TJS125, TWS105 and other components of the omentum film The stickiness of leather is average.
