Information

With the development of the society and the progress of technology, the application of new materials is more and more widely, TPU since the early 1980 s from the military to dual-use, and given priority to with civil, increasing product varieties brand, increasing the scale of production, in the national economy departments and the daily life of people has become increasingly important role in all respects.

TPU performance advantages

 

1. Wide hardness range: products with different hardness can be obtained by changing the ratio of each reaction component in TPU, and with the increase of hardness, the products still maintain good elasticity and wear resistance.

 

2. High mechanical strength: TPU products have outstanding bearing capacity, impact resistance and shock absorption.

 

3. Outstanding cold resistance: The glass transition temperature of TPU is relatively low, and it maintains good elasticity, flexibility and other physical properties at minus 35 degrees.

4. Good machining performance: common thermoplastic materials can be used for processing, such as injection molding, extrusion, calendering and so on. Polymer alloys with complementary properties can be obtained by processing with some polymer materials.

 

5. Oil resistance, ozone resistance, aging resistance, radiation resistance, low temperature resistance, good sound permeability, strong adhesion, excellent biocompatibility and blood compatibility. These advantages are the reason why polyurethane elastomers are widely used in military industry, aerospace, acoustics, biology and other fields

TPU is gradually replacing PVC in the field of medical devices

 

When selecting polymers to be used in the manufacture of plastic medical devices, such as medical bags and catheters, it is necessary to consider not only whether the polymeric materials can meet the functional requirements, but also the safety requirements of the final application. For decades, polyvinyl chloride (PVC) has been widely used in the manufacture of medical devices due to its low cost and excellent function after softening. But manufacturers around the world are starting to wean themselves off PVC for a variety of reasons, not least because medical devices containing PVC release harmful chemicals when used routinely and disposed of.

TPU is a reliable and high quality alternative to PVC. For many manufacturers, it can not only meet the needs of medical device applications, but also safer, is the ideal material to replace PVC

TPU is gradually replacing PVC in the field of film

 

 

PVC film is widely used in the fields of plastic film, plastic bag and plastic film depending on its low price. Even so, DUE to the incomparable advantages of PVC, TPU film is being replaced by PVC. TPU thin film has high strength, high toughness, abrasion resistance, oil resistance, cold resistance, aging resistance, environmental protection, non-toxic, degradable and other excellent characteristics that no other plastics and rubber can match. It has excellent properties of waterproof, moisture permeability, windproof, cold proof, anti-bacteria, anti-UV and so on, which can be applied in many industrial and civil fields. It is a kind of green film and an ideal substitute for PVC film.

TPU films have excellent properties and a wide range of hardness, resistance to deformation, nicks and scratches. Moreover, even under these enhanced conditions, TPU films still perform well in terms of elasticity and wear resistance. At the same time, TPU thin film has excellent performance in bearing capacity, resistance to strong impact force, and reduction and reduction of seismic activity. In a word, TPU thin film has high mechanical strength. Of course, PVC materials tend to harden in winter, and THE cold resistance of TPU film is very prominent. Elasticity, flexibility and other properties do not deteriorate, even at minus 35 degrees. And, its processing performance is good, through injection molding, extrusion, calendering can be formed, plus oil resistance, water resistance, mold resistance, good regeneration benefit, so the comprehensive efficiency is very excellent. PVC due to the need to add a lot of additives, environmental performance at a great discount is well known. TPU film not only has excellent properties of high tension, high tension, toughness and aging resistance, but also is a mature environmental protection material, which is very consistent with the psychological consumption demand of current consumers.

TPU film can be applied to trademark on the surface of the sole and shoes decoration, air bag, air cushion, wrapped, etc., coupled with the molding process is convenient, calendering, stretch film, blown film, preparation, coating process such as to be able to make the TPU film very widely applied on sneakers, and expanded to the medical equipment, fitness equipment, car seat materials, umbrellas, leather bags and other fields. The mechanical properties and elastic toughness of TPU film are beyond the reach of ordinary PVC products, and its good reaction at low temperature and excellent quality in environmental protection all indicate that TPU film has incomparable advantages over PVC

TPU Gradually replace PVC in the field of wire and cable

 

The cable sheath must protect the main insulating part of the interior from physical damage such as climate and moisture in the external environment and friction. Over the past few years, TPU has been gradually replacing many materials, especially PVC and synthetic rubber, in various cable applications. TPU provides tear resistance, wear resistance and bending characteristics. High and low temperature resistance is the key to cable performance. In the Chinese market, advanced cables such as control cables and power cables are only used with TPU protective covers to protect the designed complex wires and cables. TPU is used for cable sheath from low voltage to IKV due to its unparalleled hardness, low temperature flexibility, wear resistance, environmental resistance and weather resistance. These features extend the cable's durability and service life! The biggest advantage of using TPU materials lies in environmental protection!

The cable sheath must protect the main insulating part of the interior from physical damage such as climate and moisture in the external environment and friction. 1. Flexibility, mainly spring wire, computer wire, wire in power tools, mouse wire, USB cable, mobile phone data cable, etc. 2. Weather resistance, high and low temperature resistance is the key to cable performance, especially for cables operating in cold climates, such as cables dragged in ice and submarine cables. The material is required to maintain good elasticity, flexibility and other physical properties at minus 35 degrees. 3, hydrolysis resistant, mainly polyether type TPU4, antimicrobial, mainly used in medical equipment wire and cable, cable requirements antibacterial, mildew proof, no energy release. 5, fire retardant performance, can meet the requirements of V0-V2 fire, UL certification, yellow card, no halogen, little smoke toxic substances produced during combustion, with good fire resistance. TPU provides tear resistance, wear resistance and bending characteristics. High and low temperature resistance is the key to cable performance. In the Chinese market, advanced cables such as control cables and power cables are only used with TPU protective covers to protect the designed complex wires and cables. TPU is used for cable sheath from low voltage to IKV due to its unparalleled hardness, low temperature flexibility, wear resistance, environmental resistance and weather resistance. These features extend the cable's durability and service life! The biggest advantage of using TPU materials lies in environmental protection!

6. Good processing performance: Most Chinese enterprises that use TPU to produce wires and cables are small in scale, and TPU products are required to be processed by common thermoplastic material processing methods, such as injection, extrusion, rolling and so on. At the same time, the enterprise requires TPU and some polymer materials can be processed together to get complementary properties of polymer alloy, 7, wear resistance, polyester polyurethane is not resistant to hydrolysis, so the industry of wire and cable polyether polyurethane.
