What is TPU( thermoplastic polyurethane) granules ?
TPU name is thermoplastic polyurethane elastomer rubber, this material can soften at a certain heat, but can remain unchanged at room temperature. Used in shoes to stabilize the role of support.
The so-called elastomer refers to the glass transition temperature is lower than the room temperature, the elongation at break is >50%, and the resilience is relatively good after the external force is removed.
What is the difference between Polyether TPU and Polyester TPU?
There are significant differences in the characteristics of polyether-type and polyester-type TPU. Polyether TPU has high strength, hydrolysis resistance and high resilience, and good low temperature performance. Polyester TPU has better tensile properties, flexural properties, wear and tear resistance, as well as solvent resistance and resistance to higher temperatures.
In the production of raw materials and formulations, the differences between polyether TPU and polyester TPU are mainly reflected in the composition of raw materials, molecular mass distribution and influencing factors.
Polyether TPU in the soft section of the molecular weight distribution is narrower, polyester TPU soft section is wider distribution. Polyether TPU shows excellent tensile strength, tear strength and abrasion resistance in mechanical properties, while polyester TPU has more advantages in drug resistance, transparency and bacterial resistance.
In terms of hydrolytic stability, polyester-type TPU has improved hydrolytic resistance after carbodiimide protection. And at high temperature, polyether ester type TPU and polyether type TPU have the best hydrolysis resistance.
Polyester TPU is susceptible to water molecules and fracture, and the acid generated by hydrolysis can catalyze further hydrolysis of polyester. An increase in the number of methylene groups in the polyester glycol raw material improves the water resistance of the resulting polyester-based polyurethane elastomers. TPU with smaller ester group content also has better water resistance. Similarly, the water resistance of polyurethane elastomers made from polyesters synthesized using long-chain dibasic acids is better than that of polyester-type polyurethanes with short-chain dibasic acids.
Polyester-type soft TPUs can be attacked by microorganisms in prolonged contact with moist soil, whereas polyether-type soft or rigid TPUs as well as polyether-type TPUs are usually not attacked by microorganisms.
What is the hardness range of TPU resin ?
As an elastomer, TPU is a material between rubber and plastic, which can be seen from its rigidity, which can be measured by the elastic modulus. The elastic modulus of rubber is usually 1~10 MPa, TPU is 10~1000Mpa, and plastic (nylon, ABS, PC, POM) is 1000~10000Mpa.
The hardness range of TPU is quite wide, from Shore A 60 to Shore D 80, and it has high elasticity in the whole hardness range. TPU has a wide temperature range of -40~120 ° C and is flexible without the need for plasticizers. TPU has good resistance to oils (mineral oils, animal and vegetable oils and lubricants) and many solvents; TPU also has good weather resistance and excellent resistance to high-energy rays. The well-known wear resistance, tear resistance, flexion strength are excellent; High tensile strength, large elongation and low long-term compression permanent deformation rate are the significant advantages of TPU.
Product name |
TPU resin thermoplastic polyurethane granules /pellets |
Appearance |
High transparent/white ,customized color |
Characteristics |
1. A wide range of hardness: by changing the ratio of each reaction component of TPU, products with different hardness can be obtained, and with the increase of hardness, the product still maintains good elasticity and wear resistance.
2. High mechanical strength:TPU products have outstanding bearing capacity, impact resistance and shock absorption performance.
3. Outstanding cold resistance: The glass transition temperature of TPU is relatively low, and it still maintains good elasticity, flexibility and other physical properties at minus 35 degrees.
4. Good processing performance :TPU can be processed by common thermoplastic material processing methods, such as injection molding, extrusion, calendering and so on. At the same time, TPU and some polymer materials can be processed together to obtain complementary polymer alloys.
5. Resistant to oil, water and mold.
6. Good reproducibility. |
