SiSiC Silicon Carbide Composite Polyurethane Bushings are advanced hybrid wear-resistant sleeves, engineered by combining reaction bonded silicon carbide (RBSiC / SiSiC) with high-performance polyurethane elastomers. This dual-layer design leverages the extreme hardness and abrasion resistance of SiSiC with the shock-absorbing flexibility of polyurethane, creating a bushing solution ideal for dynamic material flow systems under severe wear and impact conditions.

These composite bushings are commonly used in mining, power generation, cement, and chemical processing, especially in applications involving abrasive slurries, ore transport, or cyclonic flow where both mechanical impact and chemical corrosion are major concerns.

Key Advantages

Silicon carbide products are an advanced material widely used in high temperature, high pressure and high frequency environments.:

High Strength

Composite structure with ordinary steel outer wall meets strength requirements for various industrial processes.

Exceptional Wear Resistance

Inner ceramic layer (≥95% content) provides 30x better wear resistance than carbon steel pipes.

Corrosion Immunity

Corrosion-resistant composite layer enables use in acid, alkali, and salt environments.

High Bond Strength

Organic polymer matrix with inorganic ceramic reinforcement provides 14-16 MPa peeling strength (100x stronger than ordinary lining).

Wide Temperature Range

Continuous operation from 40°C to 200°C, with peak resistance up to 260°C.

Extended Service Life

Elbows show no significant wear after 1-2 years, outperforming thick-walled cast steel by nearly 10x.

Performance Comparison

Silicon carbide ceramic-lined pipes offer superior performance compared to traditional materials:

  • Carbon Steel Pipes 30x less wear resistance
  • Wear-Resistant Alloy Cast Steel 10x less wear resistance
  • Cast Stone Pipes Brittle, prone to cracking
  • Rubber-Lined Pipes Limited temperature resistance
