TPU is a kind of thermoplastic elastomer with excellent comprehensive performance. It has high strength, good elasticity, outstanding abrasion resistance, and excellent chemical resistance.
-
Processing Properties
- Good Fluidity: TPU used for injection molding has good fluidity, which allows it to fill the mold cavity quickly and accurately during the injection molding process, enabling the production of complex – shaped parts with high dimensional accuracy.
- Wide Processing Window: It has a relatively wide processing temperature range, which provides convenience for the injection molding process. It can be processed at different temperatures according to specific product requirements and mold characteristics, while still maintaining good molding quality.
- Fast Cycle Times: TPU has a fast solidification rate after being injected into the mold, which shortens the cooling time and thus enables shorter cycle times for the injection molding process. This helps to improve production efficiency and reduce production costs.
-
Mechanical Properties
- High Tensile Strength: The injection – molded TPU parts have high tensile strength, which can withstand large tensile forces without breaking. This makes it suitable for applications that require high – strength materials, such as in the automotive and industrial fields.
- Excellent Elasticity: TPU exhibits excellent elastic properties, being able to recover its original shape quickly after being deformed. This makes it ideal for applications that require repeated deformation and recovery, such as in footwear and sports equipment.
- Good Impact Resistance: It has good impact resistance, which can effectively absorb impact energy and protect the product from damage when subjected to external impacts. This property is very important in applications where the product may be subject to sudden impacts, such as in electronic device casings.
-
Chemical Resistance
- Resistant to Oils and Solvents: TPU has good resistance to oils and many solvents. This makes it suitable for use in environments where it may come into contact with oils and chemicals, such as in the automotive and mechanical industries.
- Weather Resistance: It has excellent weather resistance, being able to withstand long – term exposure to sunlight, rain, and other outdoor environmental factors without significant degradation in performance. This makes it suitable for outdoor applications, such as in outdoor furniture and building materials.
In summary, injection – molded TPU offers a combination of excellent processing properties, mechanical properties, and chemical resistance, making it a versatile material for a wide range of applications in various industries.
