EVA hot melt film melting point and melting temperature range

EVA hot melt film is a kind of hot melt film, which plays an indelible role in the material composite under low temperature conditions. In particular, the application on sponge and foam products is irreplaceable. Since it is also a hot melt adhesive, today we will understand what the melting point and melting temperature range of EVA hot melt adhesive film is.

EVA hot melt film is a low melting point hot melt film

The main component of EVA hot melt film is EVA, that is, vinyl acetate copolymer, because of the composition itself, the melting point temperature is only about 70 degrees Celsius, this temperature is already very low in the hot melt film, so EVA hot melt film belongs to the low melting point of the hot melt film, we call it low temperature EVA hot melt film.

The melting temperature range of EVA hot melt film is introduced

The melting point of the hot melt film is not a single value, we will add how many degrees Celsius or so when introducing, so the melting point of the hot melt film should be accurately called the melting temperature range. The melting range of EVA hot melt film is generally between 60℃-85℃, and there will be a slight difference according to the specific model, such as the melting range of HJV85 EVA hot melt film is 65℃-80℃, and the melting range (melting temperature) of HJV90 EVA hot melt film is 70℃-85℃.

There is also a difference between the melting temperature and the use temperature of EVA hot melt film

Under normal circumstances, the use temperature of hot melt film will be increased by 20-30 ° C on the basis of melting temperature, so as to ensure that the hot melt film will be completely melted to achieve the best bonding ability, EVA hot melt film is no exception, so its use temperature range is recommended between 90-120 ° C, different models of EVA hot melt film although the melting point is different. But the use of temperature need not be deliberately adjusted.
