Application of Water-Resistant Hot-Melt Adhesive Film in the Hat-Making Industry

Application of Water-Resistant Hot-Melt Adhesive Film in the Hat-Making Industry

Water-washable hot melt adhesive films represent a relatively prominent subcategory within the hot melt adhesive film category. They are widely used in processes such as garment manufacturing, footwear production, and hat making. The hot melt adhesive product line encompasses a wide variety of types, including hot melt adhesive sticks, hot melt adhesive pellets, hot melt adhesive films, hot melt adhesive mesh films, and double-sided adhesive interlinings for hot melt bonding.

What should you pay attention to when choosing hot melt adhesive?

What should you pay attention to when choosing hot melt adhesive?

The adhesion of hot-melt glue is divided into initial adhesion and final adhesion. Only when the initial adhesion and final adhesion are consistent can the hot-melt glue maintain stable bonding with the adhered material. During the production of hot-melt glue, it is essential to ensure that the glue possesses antioxidant properties, resistance to halogens, acid-alkali resistance, and plasticizing ability. Since the adhesion performance of hot-melt glue varies depending on the material of the adhered object, it is crucial to select the appropriate hot-melt glue based on the specific material being bonded.

Feasibility Study on the Application of TPU Polyurethane Elastomers in Tires

Feasibility Study on the Application of TPU Polyurethane Elastomers in Tires

TPU (Thermoplastic polyurethanes) is a thermoplastic polyurethane elastomer rubber. It is primarily categorized into polyester-based and polyether-based types. TPU boasts a wide hardness range (60 HA to 85 HD), excellent wear resistance, oil resistance, transparency, and superior elasticity. As a result, it finds extensive applications in fields such as daily-use products, sporting goods, toys, and decorative materials. Halogen-free flame-retardant TPU can also replace soft PVC to meet the growing environmental requirements across various industries.

When choosing between TPE and TPU for elastomer products, which would you select?

When choosing between TPE and TPU for elastomer products, which would you select?

Both TPE and TPU are soft materials, both possessing excellent rubber-like elasticity. In comparison, TPE excels in terms of tactile comfort, while TPU demonstrates superior elasticity and strength. For products with lower hardness (such as below 30A), TPE is the preferred choice, as it can provide anti-slip, cushioning, shock-absorbing, and resilient effects. On the other hand, for products requiring high elasticity at higher hardness levels (80A and above), TPU is the better material to use.

The principle and structure of TPE/TPU products that change color in response to temperature at 31°C

The principle and structure of TPE/TPU products that change color in response to temperature at 31°C

Thermochromic pigments are prepared from electron-transfer-type organic compound systems. Electron-transfer-type organic compounds are a class of organic chromophoric systems characterized by a unique chemical structure. At a specific temperature, electron transfer causes changes in the molecular structure of these organic compounds, thereby triggering color transitions.
