5 issues worth paying attention to about TPU hot melt adhesive film
The application of TPU hot melt adhesive film can be said to be more and more extensive. It can be seen in clothing, shoe materials, bags, plastics, and even high-end products. When applying TPU hot melt adhesive film, how many of you Issues that have to be paid attention to.
1. The advantages of TPU hot melt adhesive film
Washing resistance, bending resistance, cold resistance, good adhesion, hydrolysis resistance, easy processing, stable quality, favorable price, wide application
2. TPU hot melt adhesive film The compounded viscose material is easy to wrinkle, and the reason why the bubbles of the TPU hot melt adhesive film are not glossy
The temperature of the TPU hot melt adhesive film is too high, and the temperature needs to be adjusted to match the melting point of the TPU hot melt adhesive film.
3. The finished shoes made of TPU hot melt adhesive film will be degummed when passing through the oven
1. The melting point of the TPU hot melt adhesive film used is too low.
2. The drying temperature used is too high and the thickness of the TPU hot melt adhesive film is not enough
3. It is necessary to choose a relatively stable TPU hot melt adhesive film and debug related processes
4. The stored TPU hot melt adhesive film will turn yellow and deteriorate
Generally, the yellowing resistance of TPU hot melt adhesive film is between grades 3, 5 and 4. If the product is sealed in a package, it can be stored for one to two years. If it is not packaged, its shelf life is three to three About five months, usually stored in a cool and dry place to avoid deterioration
5. Poor adhesion fastness of leather
1. The material used has the effect of anti-sticking
2. The thickness of the TPU hot melt adhesive film is not enough
3. Poor temperature operation process
4. Adjust the thickness of the TPU hot melt adhesive film according to the conventional process and the thickness of the TPU hot melt adhesive film used.
TPU hot melt adhesive film is divided into high, medium and low temperature. Different temperatures are selected according to different industry products. The use process is fast and convenient, and the cost is low. It is the best choice for composite bonding.
