PES Hot Melt Film

PES hot melt adhesive film is made from high-performance polyethersulfone (PES) material, featuring excellent high-temperature resistance, superior mechanical strength, and outstanding chemical stability. The film melts quickly upon heating, creating a strong, heat-resistant bond after cooling, suitable for demanding industrial and electronic applications.

PES hot melt film withstands high temperatures up to 200℃ and above, offers excellent corrosion resistance and dimensional stability, and is solvent-free and environmentally friendly. It is widely used in electronics, automotive, aerospace, high-end manufacturing, and medical device industries.
