About Melting Point and Operating Temperature of Hot Melt Adhesive Film

Hot-melt adhesive film products are one type of hot-melt adhesive products. Hot-melt adhesives are made into films, and kept the basic characteristics the same hot-melt adhesives. Melting point is one of the parameters of hot melt adhesive film products, which means the hot melt adhesive film will melt at a specific temperature.

The hot melt adhesive film is a kind of mixture, the melting is a process, no exact temperature point. The melting point temperature of hot melt adhesive film is mean temperature range, such as 70℃~85℃. 

For example, the melting point range of TPU hot melt adhesive film is 120℃~140℃, which means the TPU hot melt adhesive film starts to melt from 120℃, and completely melts until 140℃. Therefore, the operating temperature should to be at minimum 120 ℃ to make the hot melt adhesive film completely melt, the actual operating temperature is 140 ℃ higher than the melting point temperature about 20℃, better effect. 

POLYSAN is professional China plastic film factory TPU hot melt adhesive film, EVA hot melt adhesive film, PES hot melt adhesive film, laminated with different material, with different melting point and operating temperature.
