TPU
Brief introduction:
Thermoplastic polyurethane (TPU) is a block copolymer consisting of alternating sequences of hard and soft segments. Its adaptability is due to the presence of both these hard and soft segments in its chemical structure. The proportion of hard and soft segments can be manipulated to produce a wide range of hardness. A greater ratio of hard to soft segments will result in a more rigid TPU.the hard segments are isocyanates, and can be classified as either aliphatic or aromatic depending on the type of isocyanate. The soft segments are made of a reacted polyol. In addition to the ratio of hard to soft segments in a given grade of TPU, the type of isocyanate and polyol are responsible for the properties of the resulting TPU.

Note:
▲ Ensure that the material stays in the dryer for 4h, because the tpu raw material is easy to absorb moisture; the viscosity of the material is very sensitive to temperature and its changes. It is necessary to pay attention to the temperature during the reaction and the local temperature control of the die head.
▲ The structural design of the mold should ensure the smooth passage of the materials and do not allow the stagnation of the materials; due to the characteristics of the tpu material, the transmission power of the processing equipment is 1.5 to 2.0 times larger than the transmission power of some general plastic processing
