TPU has been providing benefits to designers, manufacturers and end users for over 50 years. The proportion of hard and soft segments can be manipulated to produce a wide range of hardness.
The look and feel of TPU is just as versatile. Data are obtained from specimens extruded under carefully controlled conditions from representative samples of the materials described herein. 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.
Processing Grades of TPU exist for every method of thermoplastic processing. For outdoor applications requiring a clear, nonyellowing product, our aliphatic TPUs are preferred.
TPU Film Manufacturer A variety of tpu films are derived from three different TPU chemistries, all of which are easily manufactured, formed and fabricated by conventional methods and are receptive to Radio Frequency RF welding.
Chemistry A TPU is a block copolymer consisting of alternating sequences of hard and soft segments. TPU is ideal for water circulation devices and other medical applications such as hot and cold therapy devices due to its ability to maintain performance over a wide range of temperatures.
TPU is particularly suited for hot and cold therapy devices because of its ability to maintain performance over a wide range of temperatures.
Compared to other polymers, TPU-based film exhibit outstanding toughness, flexibility, and abrasion resistance. TPU is compatible with a variety of processing equipment.
No assurance can be implied that all articles will have the same properties as those listed.
Wiman TPU film is ideal for water circulation devices and other medical applications. Our ether-based grades resist mold and hydrolysis when exposed to water and high humidity environments, while our ester-based grades are generally preferred for applications where the film will be in contact with oils or fuels.
The soft segments are made of a reacted polyol. Different specifications of TPU are optimized for processes such as injection moldingextrusionblow moldingovermoldingand calendaring.Partly bio-based segmented thermoplastic polyurethane (TPU) formulations were developed to fulfill the thesis of segmented TPUs starting from an aliphatic diisocyanate, a polyether polyol as macrodiol and a bio-based short diol as chain extender (CE), in pres - ence of a catalyst.
For further application, the sys. Thermoplastic Polyurethane (TPU) is a highly versatile material with superior physical properties but high cost.
Melt blending of TPU with Polyolefins (PO) can lower the cost and improve mechanical and chemical properties. Since TPU and PO are completely immiscible polymers, property enhancement cannot be attained.
TPU Film – Thermoplastic Polyurethane Film Wiman Corp is ideal for a wide variety of thermoplastic polyurethane applications.
Compared to other polymers, TPU-based film exhibit outstanding toughness, flexibility, and abrasion resistance. Thermoplastic polyurethane elastomers (TPU) for its thermoplastic polyure-thane elastomers (TPU). The material Elastollan has especially good physical pro-perties, making it suitable for thermoplastic polyurethane (PU).
