|---|---|---|
| Thickness | mm | 0.5-1.2 |
| Density | g/cm³ | 1.1-1.3 |
| Hardness | Shore A | 70-90 |
- Thickness: The thickness of TPU composite silver fox fur fabric is usually between 0.5 and 1.2 mm, a range that ensures the flexibility of the material and provides sufficient cushioning.
- Density: Its density is about 1.1 to 1.3 grams per cubic centimeter, which is lighter than traditional silicone materials, while maintaining higher strength.
- Hardness: When measured with Shore A hardness meter, the hardness range of TPU composite silver fox fur fabric is 70 to 90, indicating that it has a certain degree of rigidity and softness.
In addition, the addition of silver fox velvet fabric makes the surface of the material have a delicate fleece texture, which significantly enhances the tactile experience, and also enhances friction and prevents electronic devices from sliding off.
(Bi) Chemical Properties
The chemical properties of TPU composite silver fox fur fabric are mainly manifested in chemical corrosion resistance and environmental protection, which is an important guarantee for its long-term and stable use in various environments.
- Chemical corrosion resistance: TPU film itself has strong oil resistance, acid and alkali resistance and ultraviolet resistance, and can withstand the corrosion of various chemical substances that may be exposed to in daily use. According to the research results of literature [1], after one year of exposure in simulated outdoor environment, TPU materials have reduced their mechanical properties by less than 5%, showing excellent durability.
- Environmental: Silver fox velvet fabric is made of natural or recycled fibers, which meets the needs of modern consumers for sustainable development. At the same time, TPU film can be recycled and reused to further reduce the environmental burden.
(III) Mechanical properties
The mechanical properties of TPU composite silver fox fur fabric are the core of its cushioning technology, mainly including indicators such as tensile strength, tear strength and rebound.
| parameter name | Unit | Typical value range |
|---|---|---|
| Tension Strength | MPa | 20-40 |
| Tear Strength | kN/m | 20-35 |
| Resilience | % | 85-95 |
- Tenable strength: The tensile strength of TPU composite silver fox fur fabric can reach 20 to 40 megapas, which is much higher than that of ordinary silicone materials, ensuring that it is not easy to break when subjected to external forces.
- Tear Strength: Its tear strength range is 20 to 35 kN/m, indicating that the material has strong tear resistance and can maintain overall integrity even if it is locally subjected to stress.
- Resilience: The rebound of up to 85% to 95% allows the TPU composite silver fox sued fabric to quickly return to its original state after absorbing the impact, thereby achieving the buffering effect of multiple cycles.
To sum up, TPU composite silver fox fur fabric has become an ideal material choice for electronic equipment protective covers with its superior physical, chemical and mechanical properties.
3. The buffering mechanism of TPU composite silver fox sued fabric
The key to the TPU composite silver fox fabric being able to shine in the field of electronic equipment protective covers is its unique buffering mechanism. This mechanism is mainly achieved through three links: energy absorption, stress dispersion and dynamic recovery, thereby effectively reducing the damage caused to the equipment by external shocks.
(I) Energy absorption
When the electronic device falls unexpectedly, the TPU composite silver fox fur fabric will first absorb part of the impact energy through its own elastic deformation. As the core layer of the material, the TPU film contains a large number of flexible segments in its molecular chain structure, which will deform when subjected to external forces, convert kinetic energy into internal energy and store it inside the material. This part of the energy will then be slowly released in the form of thermal energy to avoid direct damage to the equipment.
According to the research data in literature [2], the energy absorption efficiency of TPU materials can reach more than 60%, which is much higher than that of traditional rubber materials. Table 1 shows the comparison of the ability of different materials to absorb energy under the same conditions:
| Material Type | Energy Absorption Efficiency (%) |
|---|---|
| TPU composite silver fox fur fabric | 65 |
| Ordinary silicone | 42 |
| Foaming EVA | 50 |
(Bi) Stress dispersion
In addition to energy absorption, TPU composite silver fox fur fabric can further reduce local pressure through stress dispersion mechanism. The porous structure of the silver fox velvet fabric makes the material surface have a larger contact area, thereby evenly distributing the impact force concentrated at a certain point to a larger range. This dispersion effect not only reduces the risk of damage caused by excessive stress on a single point, but also extends the service life of the material.
Study shows that the stress dispersion coefficient of TPU composite silver fox velvet fabric is about 1.8, meaning that it can disperse the impact force to a region 1.8 times the original value. In contrast, the stress dispersion coefficient of ordinary silicone materials is only 1.2, showing the significant advantage of the former in impact resistance.
(III) Dynamic Reply
After
, the dynamic recovery capability of TPU composite silver fox fur fabric adds icing on the cake to its cushioning performance. Thanks to the high resilience of the TPU film, the material can quickly return to its original state after absorbing the impact, and will not permanently deform due to long-term compression. This feature is especially important for electronic devices that need to withstand repeated shocks frequently, as it ensures that the protective case is always in good condition.
Experimental data show that after 10,000 cycle compression tests, the TPU composite silver fox fur fabric has a dimensional change rate of only 0.5%, while the ordinary silicone material has a 2.8%. This shows that the TPU composite silver fox fur fabric shows extremely high stability in dynamic resumption.
