Silicon Carbide for Wear-Resistant & Anti-Slip Shoe Soles: Brief Introduction
Core Advantages: Featuring high hardness, excellent wear resistance, stable friction coefficient and acid & alkali resistance, silicon carbide serves as a premium functional filler and aggregate for high-performance wear-resistant and anti-slip shoe soles.
1. Working Principles
Improved Wear Resistance
With a Mohs hardness of 9.5, silicon carbide is far harder than base materials such as rubber, EVA and PU. When blended into sole materials, it effectively reduces wear caused by long-term friction and extends the service life of shoe soles.
Enhanced Anti-Slip Performance
Granular silicon carbide forms micro rough textures on the sole surface to boost ground grip. It maintains stable friction on dry, wet and oil-contaminated surfaces, making it ideal for safety shoes, work boots and outdoor footwear.
Excellent Environmental Resistance
It is resistant to oil, acid, alkali and extreme temperatures, and retains stable performance in harsh environments like outdoor sites, factories and construction sites.
2. Common Specifications for Shoe Soles
- Types: Green silicon carbide is the primary choice. It has a light color, balanced friction performance and good color matching compatibility. Black silicon carbide delivers higher hardness and is mainly applied to heavy-duty safety shoes.
- Grain Sizes: 80# – 320# are widely used
- Coarse grain (80# – 120#): Superior anti-slip effect, suitable for work and construction safety shoes.
- Medium & fine grain (180# – 320#): Balanced anti-slip performance, comfort and appearance, the mainstream option for casual and outdoor shoes.
- Particle Shape: Angular grains, which provide better anti-slip effect than round particles.
3. Application Methods
- Blending & Mixing: Mix silicon carbide powder or fine grains with raw materials including rubber, TPU and PVC for overall modification, achieving full sole wear resistance and anti-slip performance.
- Surface Coating & Embossing: Scatter silicon carbide particles on the sole surface during molding, or apply a composite anti-slip rubber layer to prioritize surface anti-slip capability.
4. Applicable Footwear
Industrial safety shoes, construction work shoes
Outdoor hiking shoes, work boots, kitchen anti-slip shoes
