Application of flexible leather composite TPU film fabric in electronic equipment protective cover
Introduction
With the rapid development of technology, electronic devices such as smartphones, tablets and laptops have become an indispensable part of people’s daily lives. To extend the service life of these devices and improve their aesthetics, protective covers become an essential accessory. Flexible leather composite TPU film fabrics have gradually become an ideal choice for high-end electronic equipment protective covers due to their excellent performance and unique design. This article will introduce in detail the application of flexible leather composite TPU film fabric in electronic equipment protective covers, and will quote famous foreign literature for support.
1. Overview of flexible leather composite TPU film fabric
1.1 Material composition and characteristics
The flexible leather composite TPU film fabric consists of two parts: the upper layer is a soft and textured leather material, and the lower layer is a thermoplastic polyurethane (TPU) film. This combination not only retains the natural beauty and touch of the leather, but also gives the product excellent wear and impact resistance. In addition, the TPU film has good flexibility and resilience, so that it can closely fit the shape of the electronic device and provide all-round protection.
Table 1: Main characteristics of flexible leather composite TPU film fabric
| Features | Description |
|---|---|
| Abrasion resistance | High strength and wear resistance, suitable for frequent use of electronic equipment |
| Impact resistance | Excellent impact resistance, effectively prevent damage caused by accidental drops |
| Flexibility | Excellent flexibility and resilience ensure that it is not easy to deform after long-term use |
| Touch | Soft touch similar to natural leather, enhance user experience |
| Waterproof | TPU membrane has certain waterproof functions to prevent liquid intrusion |
| Environmental | Use environmentally friendly materials to reduce the impact on the environment |
1.2 Current status of foreign research
Flexible leather composite TPU film fabrics perform excellently in durability and comfort, according to research reports from the American Society for Materials Testing (ASTM). The European Federation of Chemical Industry (CEFIC) also pointed out that this material has broad application prospects in the field of electronic equipment protection. A Royal SocietyA study shows that the physical properties of TPU membranes can be optimized by adding different types of additives to meet the needs of specific application scenarios.
2. Application advantages of flexible leather composite TPU film fabric in electronic equipment protective covers
2.1 Provide comprehensive protection
Flexible leather composite TPU film fabric can provide all-round protection for electronic devices, especially for vulnerable screens and corners. The high elasticity and impact resistance of the TPU film enable the protective case to quickly return to its original state when impacted, avoiding damage to the internal equipment. At the same time, the addition of the leather layer improves the durability of the product and reduces wear caused by friction.
2.2 Enhance user comfort experience
The soft leather surface not only increases the aesthetics of the protective cover, but also enhances the user’s grip and touch. Research shows that protective covers using flexible leather composite TPU film fabrics are more willing to hold for a long time than traditional plastic or silicone products. In addition, the sweat-absorbing and breathable nature of the leather also helps keep the hands dry and reduce the risk of sliding.
2.3 Enhance brand value
Protection covers using flexible leather composite TPU film fabrics are often regarded as high-end products, which can significantly enhance the brand’s market competitiveness. Data from the TÜV certification agency in Rhine, Germany, showed that protective covers using this material scored higher in consumer satisfaction surveys, especially among young consumer groups. This shows that high-quality materials can not only improve the actual performance of the product, but also enhance brand image and user loyalty.
3. Technical parameters and manufacturing processes of flexible leather composite TPU film fabric
3.1 Technical parameters
The specific technical parameters of flexible leather composite TPU film fabric are shown in the following table:
Table 2: Technical parameters of flexible leather composite TPU film fabric
| parameter name | Unit | Typical | Testing Standards |
|---|---|---|---|
| Thickness | mm | 0.5 – 1.2 | ISO 4762 |
| Tension Strength | MPa | 20 – 30 | ASTM D638 |
| Elongation of Break | % | 400 – 600 | ASTM D638 |
| Hardness (Shaw A) | 80 – 90 | ASTM D2240 | |
| Surface resistivity | Ω/sq | 10^8 – 10^10 | IEC 61340-5-1 |
| Chemical resistance | Good | ISO 4628-1 |
3.2 Manufacturing process
The manufacturing process of flexible leather composite TPU film fabric mainly includes the following steps:
- Raw Material Preparation: Choose high-quality natural leather and TPU resin as the basic material.
- Pretreatment: Clean, degreas and soften the leather to ensure smooth and free of impurities.
- Coating and Compounding: TPU resin is uniformly coated on the leather surface through advanced coating technology and is combined with high temperature and high pressure equipment.
- Currecting and forming: Put the composite material into the mold and cure it at a certain temperature and pressure to form the required shape and size.
- Quality Inspection: Conduct comprehensive quality inspection of finished products, including appearance inspection, physical performance testing and functional verification.
IV. Market prospects and development trends
4.1 Market demand growth
In recent years, the rapid development of the global electronic equipment market has promoted the demand for high-quality protective cases. According to the forecast of International Data Corporation (IDC), the global electronic equipment protective case market size will grow at an average annual rate of 8% in the next five years. Among them, flexible leather composite TPU film fabric is expected to occupy an important share in the high-end market with its unique advantages.
4.2 Trends of Technological Innovation
With the continuous emergence of new materials and new technologies, flexible leather composite TPU film fabrics are also constantly innovating and developing. For example, researchers are exploring how to further improve the wear and impact resistance of materials through nanotechnology; at the same time, the introduction of intelligent functions has also brought new development opportunities to the material. A study by the Massachusetts Institute of Technology (MIT) shows that future protective cases may have self-healing capabilities, thereby extending their service life.
4.3 Environmental protection and sustainable developmentExhibition
Around the world, the increased environmental awareness has prompted manufacturers to pay more attention to material selection and the sustainability of the production process. Flexible leather composite TPU film fabrics also show obvious advantages in this regard. On the one hand, TPU is a recyclable material that meets the requirements of a circular economy; on the other hand, by optimizing the production process, energy consumption and waste emissions can be effectively reduced. The European Commission’s relevant policies also encourage enterprises to increase investment in R&D in environmentally friendly materials and promote green transformation in the industry.
