TPU stands for thermoplastic polyurethane elastomer rubber. It\u2019s not a textile in the traditional sense, let alone leather. TPU overcomes many of the shortcomings of PVC, PU leather, and PU coating, and has made major breakthroughs in the application of waterproof and breathable fabrics.<\/p>\n

TPU not only has most of the characteristics of rubber and ordinary plastics, but also has excellent comprehensive physical and chemical properties. It is a new type of polymer environmentally friendly material between rubber and plastic. It has both the softness of rubber and the hardness of hard plastic.<\/p>\n

\u30ce\u30ba\u30eb\u6e29\u5ea6\uff1a<\/strong> The nozzle temperature is usually slightly lower than the maximum temperature of the barrel to prevent the molten material from drooling out of the straight-through nozzle.<\/p>\n

\u91d1\u578b\u6e29\u5ea6\uff1a<\/strong>The mold temperature is very important for the intrinsic performance and appearance quality of TPU products. It is determined by many factors such as the crystallinity of TPU and the size of the product. The mold temperature is usually controlled by a constant temperature cooling medium such as water.<\/p>\n

The mold temperature of TPU products is generally 10~60\u2103.When the mold temperature is low, the melt freezes prematurely and produces streamlines, which is not conducive to the growth of spherulites, resulting in low crystallinity of the product and a late crystallization process, which causes post-shrinkage and performance changes of the product.<\/p>\n

The pressure in the injection molding process includes plasticizing pressure (back pressure) and injection pressure. When the screw retreats, the pressure on the top melt is the back pressure, which is adjusted by the overflow valve.<\/p>\n

Injection pressure is the pressure applied by the top of the screw to TPU. It\u2019s used to overcome the flow resistance of TPU from the barrel to the cavity, increase the rate of melt filling, and compact the melt.<\/p>\n

In other words, melt viscosity is determined by temperature and pressure, as well as TPU hardness and deformation rate. The higher the shear rate, the lower the viscosity. When the shear rate remains unchanged, the higher the hardness of TPU, the greater the viscosity.<\/p>\n

When the shear rate is constant, the viscosity decreases as the temperature increases, but at high shear rates, the viscosity is not as affected by temperature as it is at low shear rates. The injection pressure of TPU is generally 20~110MPa.<\/p>\n

Products with internal stress often experience a decrease in mechanical properties during storage and use, silver streaks on the surface, and even deformation and cracking. The way to solve these problems in production is to anneal the product. The annealing temperature depends on the hardness of the TPU product.<\/p>\n
