Wheel and Gears Materials Play An Essential Role in Automotive Interiors

As the most frequently touched interface between driver and vehicle, the coverings on the steering wheel and gear shift lever are vitally important. The materials chosen must therefore fulfill a complex set of criteria, combining long-term durability with a comfortable and secure grip, all while contributing to the cabin's overall aesthetic.

Why Do Classic Covering Choices Pose Safety and Comfort Risks?

Genuine leather, often premium top-grain hide, is a traditional and classic choice found in everything from mid-range to luxury vehicles. While it imparts a timeless, upscale ambiance, it presents practical drawbacks. The primary safety concern is its significant loss of grip when wet or damp from perspiration, making the steering wheel slippery and potentially compromising steering precision, especially in critical situations. Over time, exposure to friction, sweat, and oils can cause the leather to wear, develop an undesirable shine, and become slick, further diminishing both its luxurious feel and safe handling characteristics.

Polyurethane (PU) or Polyvinyl Chloride (PVC) synthetic leathers are common cost-effective alternatives. However, lower-quality options, particularly those using PVC, may contain plasticizers like phthalates. When a car interior heats up, these chemicals can volatilize, contributing to the "new car smell" and potentially releasing unpleasant or irritating odors. Furthermore, most PU/PVC materials are non-breathable. This lack of breathability can lead to clammy and slippery hands during summer drives, even with air conditioning, undermining comfort and the sense of a premium driving experience.

Thermoplastic Elastomers (TPE) ,although some are recyclable and soft, they have limitations in automotive applications. A key weakness is their relatively low resistance to scratching and poor aging performance under high temperatures. Prolonged exposure to intense summer UV radiation and ozone within the cabin can cause the material to become sticky, harden, discolor, or lose elasticity. This degradation not only affects the comfort of the grip but can also pose a safety risk over time.

Discover How Si-TPV Provides Better Wear Resistance, Slip Resistance and Comfort

Better Wear Resistance and Long-Term Durability
The steering wheel and gear shift knob endure constant exposure to friction, hand perspiration, and oils. Si-TPV， as an innovative elastomer, it excels in resisting wear, fading, and material degradation, guaranteeing that these critical components retain their aesthetic appeal and functional integrity for the entire lifespan of the vehicle.

Great Anti-Slip Performance
As the paramount safety consideration, a secure grip is essential. Si-TPV provides sufficient frictional force to ensure stable control, even during prolonged driving when hands may become sweaty. This is due to its excellent anti-slip properties, particularly its reliable anti-slip performance in wet conditions.

Comfort Extreme and Soft Touch
Si-TPV is characterized by its soft touch, and premium matte finish. These properties provide a comfortable and non-slippery grip on steering wheels and shift levers, enhancing both aesthetic quality and driving comfort with stable performance across varying temperatures.
