Can you keep a**.

You can consult here.

The formula is incomprehensible.

I am also producing EVA adhesive films, but the quality is not stable.

That's it, dear.

No, you can't, pro violation.

The raw material I use is PE recycled material + EVA material

EVA and PEVA do not easily form a strong bond. After EVA is formed, the polymerization has been completed and is no longer re-melted, so it cannot be directly "ironed". EVA and PEVA must be "polished" and then bonded with acetone series of "EVA special laughing adhesive".

Note: Brush and apply the glue twice, the first time with an infrared lamp to irradiate most of the dry and then apply the second time of the glue, the second time the glue irradiates to most of the dry as soon as possible, compact for 3-5 seconds (no square centimeter pressure of about 10kg) after the release of the line, you can install the phase.

How to use hot melt adhesive film: hot melt adhesive film is solid at normal temperature, and must be heated to the corresponding temperature to become sticky, put the hot melt adhesive film in the middle of two materials that need to be glued and pasted, and make it sticky by applying heat and pressure to the hot melt adhesive film.

Hot melt adhesive film is a film product with or without release liner that can be conveniently operated continuously or intermittently. It can be widely used in all kinds of fabrics, paper, polymer materials and metal bonding. Major international brands and models:

In terms of use, it is mainly used as an adhesive for products and materials, which is what we often call adhesives!

1.The hot melt adhesive has 100% solid content and void filling, which prevents edge rolling, bubbles and cracking, and the distortion, displacement and shortening of the adhered object. Because there are no solvents, the moisture content of the wood does not change, and there is no risk of fire or poisoning.

2.The bonding speed is fast, the process from gluing to the completion of bonding does not take more than a few seconds, the saw head and trimming can be completed in about 20-24 seconds, no drying time is required, and it can be used for continuous and automated wood bonding lines, which greatly improves the production efficiency and saves the cost of the plant.

3.It is widely used and suitable for bonding various materials.

4.It is possible to carry out multiple bonding, that is, the hot melt adhesive applied to the wood, and when it is cooled and cured to meet the requirements, it can be reheated for secondary bonding.

Hot melt adhesives. Adhesive fabric is possible, but you need to choose the right hot melt adhesive. There are many types of hot melt adhesives, including hot melt adhesive particles, hot melt adhesive blocks, hot melt adhesive sticks, hot melt adhesive films, hot melt adhesive web films, and hot melt adhesive powders.

The bonding process of the cloth is relatively easy, and the hot melt adhesives used are mostly hot melt adhesive web film and hot melt adhesive film. Here are some simple examples:

1) The bonding composite of non-woven fabrics is mainly made of hot-melt adhesive web film and unadhesive;

2) Hot melt double-sided tape used in garment processing.

In fact, the adhesive lining is also made of hot melt adhesive web film slitting;

3) Cloth lamination for flocking transfer printing and textiles can be made with either hot-melt adhesive film or hot-melt adhesive web film, depending on the process.

4) In the composite of automotive interior fabrics, the application of hot-melt adhesive web film is more extensive!

The hot melt adhesive film can bond most of the cloth, and there is generally no problem, but it still depends on the specific material and application, and not all hot melt adhesive films are suitable for the bonding of cloth. For another example, if cloth bonding is in the field of clothing, it needs to have washable requirements, then it may be necessary to use TPU hot-melt adhesive film, and hot-melt adhesive film of other materials may not meet the washing requirements.
