TPU(thermoplastic polyurethanes) bridges the material gap between rubbers and plastics. Its range of physical properties enables TPU to be used as both a hard rubber and a soft engineering thermoplastic.TPU have achieved widespread usage and popularity in thousands of products, owing to their durability, softness and colorability among other benefits. In addition, they are easy to process.
As an emerging high-tech and environment-friendly materials, TPU has many excellent properties like wide hardness range, high mechanical strength, outstanding cold resistance, good processing performance, environmentally friendly degradation, oil resistance, water resistance and mold resistance.
Applications: Solvent Adhesives, Hot-melt Adhesive Films, Footwear Adhesive.

1. Avoid breathing thermal processing fumes and vapors
2. Mechanical handling equipment can cause formation of dust. Avoid breathing dust.
3. Use proper grounding techniques when handling this product to avoid electrostatic charges
4. Pellets on the floor may be slippery and cause falls
Storage recommendations: To maintain product quality, store product in a cool, dry area. Keep in a tightly sealed container.
1. Deteriorated TPU materials cannot be used to process products.
2. Before molding, it is necessary to fully dry, especially during extrusion molding, blow molding, and film blowing molding, with stricter requirements for moisture content, especially in humid seasons and high humidity areas.
3. During production, the structure, compression ratio, groove depth, and aspect ratio L/D of the screw should be considered based on the characteristics of the material. Injection molding screws are used for injection molding, and extrusion screws are used for extrusion.
4. Based on the fluidity of the material, consider the mold structure, size of the glue inlet, nozzle size, flow channel structure, and position of the exhaust port.
