Characteristics of TPU hot melt adhesive film—how is TPU hot melt adhesive film used?
TPU hot-melt adhesive film possesses the excellent properties of conventional TPU films, as well as the heat-melting adhesion performance characteristic of hot-melt adhesive films. Conventional TPU films exhibit high tensile strength, good flexibility and bendability, weather resistance, water resistance, hydrolysis resistance, transparency, resistance to yellowing, comfort when in contact with human skin, ease of processing, and many other advantageous features.

The difference between TPU and PVC
TPU and TPV are essentially similar materials—both are thermoplastic elastomers. TPU is a replacement product for PVC. TPU is not a plastic but rather a resin. Its advantages include oil resistance, cold resistance, and resistance to aging. Its performance is dozens of times better than that of PVC.

The colorless, transparent two-component adhesive is primarily prepared by dissolving TPU resin. There are not many TPU options available on the market; currently, the main ones used are 6023 and 6029 from Jintang Technology. The ratio of 6023 to 6029 is approximately 16:9, with a total solid content ranging from 22% to 28%. Solvents commonly used include dichloromethane, DBE, acetone, methyl ethyl ketone, and toluene. The viscosity of the resulting adhesive is controlled within the range of 5,000 to 9,000 mPa·s. This adhesive features a long open time, good initial tack, high production efficiency for users, and prevents edge warping.

The domestic adipic acid market has been experiencing a narrow downward trend, with an overall subdued market atmosphere. Downstream inquiries are generally moderate, and buyers are primarily focused on securing supplies for immediate needs. Traders are in a pessimistic mood. Quotations from the East China, North China, and South China regions have all shown downward fluctuations. It is expected that the adipic acid market will continue to consolidate weakly in the near future.
