Application of soft materials for auto armrest cup holders

There are many types of soft materials. When choosing a material suitable for an auto armrest cup holder, you need to consider its physical properties, comfort, durability, and compatibility with other in-car materials. Common soft materials include:
Rubber: Rubber materials are widely used in car cup holders due to their good elasticity and anti-slip properties. Rubber can effectively absorb vibration and impact, protect beverage containers, and prevent scratches or damage inside the cup holder. The high coefficient of friction of rubber materials can prevent beverages from sliding during driving, improving safety.
Silicone: Silicone has high elasticity and good hand feel, is resistant to high temperatures and chemical corrosion, and is non-toxic and odorless, making it very suitable for parts that come into contact with food. The silicone cup holder lining is not only comfortable and durable, but also easy to clean and suitable for long-term use.
Thermoplastic polyurethane: TPU has both the flexibility of rubber and the strength of plastic, and is suitable for parts that require wear resistance and impact resistance. Its high transparency and easy processing make TPU an ideal material for soft parts in automotive interiors, providing good protection and comfort for cup holders.
Functional design of soft materials
The application of soft materials in car armrest cup holders not only improves the touch and comfort, but also enhances the user experience through functional design
Anti-slip function: The high friction coefficient of soft materials plays an important anti-slip role in cup holders. By lining the bottom and side walls of the cup holder with soft rubber or silicone, the beverage can be effectively prevented from sliding during driving, especially in sharp turns or bumpy roads.
Buffering and shockproof functions: During driving, the car body will inevitably vibrate, and soft materials can absorb and disperse these vibrations through their elasticity to prevent the beverage container from being subjected to excessive impact or collision. In particular, the use of soft materials on the inner wall, bottom and edge of the cup holder can greatly reduce the risk of beverage spillage caused by vibration.
