Comparative analysis of mainstream materials for phone cases

There are various material choices for phone cases, and different materials have their own characteristics in terms of protection, feel, and durability. The following is a comparative analysis of mainstream materials:

1. Liquid silicone gel
   Advantages: Soft and drop resistant, with a jelly like texture, strong resistance to fingerprints and dirt.
   Disadvantages: Easy to stick to hair, light colored styles may dye.
   Applicable scenarios: Users who pursue bare metal feel and high protection.
2. TPU (thermoplastic polyurethane)
   Advantages: High elasticity, impact resistance, transparent design can display the original color of the phone.
   Disadvantages: Long term use is prone to yellowing and has average wear resistance.
   Applicable scenarios: Users who prefer transparent or lightweight designs.
3. PC (polycarbonate)
   Advantages: Lightweight and transparent, restoring the natural color of the phone, and resistant to deformation.
   Disadvantages: Easy to scratch, oil stains, and fingerprints.
   Applicable scenarios: Hard shell requirements that focus on appearance restoration.
4. Metal material
   Advantages: Good heat dissipation and high-end texture.
   Disadvantages: Heavy weight, may affect signal.
   Applicable scenarios: Business or high heat dissipation demand scenarios.

5. Genuine leather/plain leather
   Advantages: The more you use it, the more textured it becomes, suitable for business style.
   Disadvantages: Afraid of water and oil, requiring regular maintenance.
   Applicable scenario: Users who pursue high-end texture.
6. Composite materials (such as TPU+PC)
   Advantages: Combining the anti drop properties of TPU with the anti yellowing properties of PC.
   Disadvantages: High cost.
   Applicable scenarios: Balancing protection and durability.
7. Kevlar aramid fiber
   Advantages: The anti drop performance is close to metal, lightweight and does not change color.
   Disadvantages: High price, few styles.
   Applicable scenarios: High end users who pursue ultimate protection.
   Other special materials
   Acrylic: The light transmittance is close to glass, but it is prone to fingerprints.
   Glass: Tempered glass shell has high strength, but is heavy.
   PP material: lightweight and anti fingerprint, but with weak protection.
   When choosing, it is necessary to weigh the protection, feel, and budget according to the needs. Liquid silicone and TPU are the mainstream choices, while composite materials and Kevlar are suitable for specific scenarios
