Hot-melt adhesive can be said to be PE wrinkle free shirt tape a very widely used "explosion" adhesive that is rarely known by the public. It is widely used because I can easily find several items containing hot melt glue from your side; it is not well-known because most of them do not know that there is such a glue that requires heating to produce viscosity . For most people, hot melt adhesives are really "both familiar and unfamiliar"! What materials can be glued to hot melt adhesives has always been a concern of everyone.
Whether it is out of curiosity about hot melt adhesives, or it is really necessary to use hot melt adhesives, a simple understanding of it is still necessary. If you want to know which materials the hot-melt adhesive can adhere to, you need to start with the type of hot-melt adhesive, because the properties of different types of hot-melt adhesives are different, and the performance of bonding with the material is a problem of compatibility.
Why do some people feel that the bonding effect is not good when using hot-melt adhesive bonding materials, it may be that the type selection is wrong, resulting in incompatibility between the two. The material type of hot melt adhesive is mainly divided according to its raw materials, which can be divided into pa hot melt adhesive with adhesive film and omentum.
Pes hot melt adhesive with adhesive film and omentum, tpu hot melt adhesive with Adhesive film and omentum, eva hot melt adhesive with adhesive film and omentum, eaa hot melt adhesive. Each of the above types of hot-melt adhesives can be divided into different models based on melting point, width, thickness, or weight, etc. At the same time, their properties are also different:
(1) Pa-type hot-melt adhesive: It has the characteristics of resistance to dry cleaning and washing, low temperature resistance of minus 40 degrees and high temperature resistance of more than 120 degrees; functional pa hot-melt adhesive is flame retardant and resistant to boiling at 100 degrees;
(2) Pes hot-melt adhesive: it has the characteristics of water washing resistance and dry cleaning resistance, low temperature resistance of minus 30 degrees, high temperature resistance of more than 120 degrees, and high bonding strength;
(3) Eva hot-melt adhesive: slightly weak in washing resistance, not dry-cleaning resistant, low melting point, low temperature resistance of minus 20 degrees, high temperature resistance of 80 degrees;
(4) Tpu hot-melt adhesive: It has the characteristics of resistance to washing and dry cleaning, low temperature resistance of minus 20 degrees, high temperature resistance of 110 degrees, good tensile properties and softness;
(5) Eaa type hot melt adhesive: good viscosity, strong tensile strength, resistance to minus 40 degrees low temperature, can be punched.
