Hot melt TPU Film Characteristics
◆ Good strength washable
◆ Low operating temperature
◆ High adhesion
◆ Better feeling
Hot melt TPU Film advantages:
1. Hot melt TPU Film is environmentally friendly and has no harmful substances: polymer hot melt adhesive is an environmentally friendly material and has no harmful solvents.
2. Fast bonding speed: heating and pressing, cooling and sticking.
3. Normal temperature and no stickiness: The film is solid at room temperature and does not stick to the hand. The film can be sold together with the product for convenient transportation and storage.
4. Hot melt TPU Film have better bonding properties than other adhesives in some areas.
5. Temperature, washing resistance, corrosion resistance, aging resistance, flame retardant and other characteristics: can be modified according to customer needs.
