What is TPU? - TPU stands for thermoplastic polyurethane and is a block copolymer consisting of alternating sequences of hard and soft segments. The proportion of hard and soft segments can be manipulated to produce a wide range of hardness. Different ratio of hard to soft segments will result in different hardness TPU. Its hardness can be highly customized and are available in a hardness range of 60A to 80D. TPU can be as soft as rubber or as hard as rigid plastics.  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. The hard segment defines the TPU's processing temperatures, its continuous and upper use temperature limits, tensile strength, chemical resistance, and adhesion characteristics. The soft segment determines the TPU's lower service temperature limits, hardness, flexibility and compression set. TPU offers flexibility without the use of plasticizers. TPU resin, Thermoplastic polyurethane possesses the high toughness, mechanical strength, bio-compatibility, and resistance against oil, chemical, hydrolysis, and bacteria. The soft segment is either a polyester or polyether type polyol. Polyester-based TPU's are preferred for applications requiring optimal physical properties and resistance to oil and hydrocarbons, while polyether-based TPU's should be considered for parts used in moisture- rich and cold temperature environments. TPU main features: · Abrasion, impact and puncture resistance · Antimicrobial and fungal resistance · Recyclable · Chemical and hydrolysis resistance · Easy-to-extrude · High moisture vapor transmission · Optical clarity · Skin contact approved · Soft · Elastic · UV resistant Thermoplastic Polyurethane can be processed easily via conventional processing methods like injection molding, extrusion, blow and compression molding etc. They are easily molded into shapes to produce shoe sole, medical castor, air tube and several other applications as discussed above. It can also be compounded to create robust plastic moldings or processed using organic solvents. TPU features with both superior performance and processing flexibility is the ideal polymer for applications in a wide variety of markets. Such as footwear, tube, castor, wire and cable, film and sheet, compounding, adhesives and specialty molded parts. Limitations of Thermoplastics Polyurethanes Drying time is required before processing can beginNot as cost-effective as other alternativesNarrower hardness range than other TPEsNarrow temperature range for processingPlease note: Drying is a critical step in ensuring TPU’s process effectively and that a good part is obtained upon molding. If moisture is not removed from the polymer effectively before processing, drying of molded parts would not take effectively leading to loss ...

Thermoplastic polyurethane is a product between rubber and plastic. It not only has high resilience and resistance to bending, tearing, impact, some non-corrosive chemicals, oils, but also has wear resistance, aging resistance, low temperature resistance, stretch resistance. As can be 100% incinerated into ash it’s a recognized recyclable environmental protection material. These properties of TPU imparts a variety of Outstanding properties to the pneumatic tube: 1.The pipe wall is smooth and uniform, the size of tube OD is stable, and the working life is long 2.Good resilience, small bending radius, easy to install and cut 3.Wear resistance, excellent mechanical properties 4.The transparent tube has high transparency and  internal fluid of tube can be clearly visible 5.Superior color capabilities and does not fade for a long time 6.Working pressure is 1.0MPa and burst pressure is 3.5MPa in Normal woking temperature (23℃) 7.Normal operating temperature range -20℃~+80℃ 8.The recommended temperature range for long-term use is -10℃~+60℃ TPU hoses are widely used for liquid transportation in general working pressure in industries, agriculture, food, medicine, civil engineering, fishery, aquaculture, garden irrigation and other fields. Such as: pneumatic pipes, hydraulic pipes, garden water pipes, oil and water pipes, oil exploration pipes, etc. Pneumatic tube is also called trachea and pneumatic hose.  TPU pneumatic tube has stable quality, high pressure resistance, weather resistance, abrasion resistance, tortuous resistance, smooth and flexible tube body, bright color, high elasticity, and bending resistance. The bending radius is small. TPU is divided into many types such as polyether TPU, polyester TPU, polycaprolactone TPU, and modified TPU. Commonly used are polyether, polyester and modified TPU. Different kinds of TPU can suit for kinds of pneumatic tubes’ special requirement. The air-passing equipment mainly uses polyester pneumatic tubes, the air-passing and water-passing equipment mainly uses polyether pneumatic tubes, and the special hoses mainly use modified TPU. Pneumatic pipes are mainly used for pneumatic and pneumatic tools, gas pipelines, instruments, machinery, lubricating oil transmission lines, circulation of non-corrosive chemical objects, process adjustment and control, automated assembly lines, laboratories, robotics, general industrial water and gardening. The production of TPU pneumatic tube requires TPU to have good plasticizing effect, no crystal point particles, and stable OD. Kunsheng K798 and K795 are specially developed and applied to pneumatic tubes, which can solve these production problems well, make the on-site production operation simple and controllable, and make the products free from defects.
