What is Gilsonite Grade A?

Gilsonite Grade A is the highest-quality form of natural bitumen (uintaite), specifically selected and processed for applications requiring stringent quality control. Sourced from the richest veins and processed with precision, this grade features:

  • Purity over 85–90%
  • Extremely low ash content (often <5%)
  • High softening point (typically >200°C)
  • Excellent solubility in aromatic and aliphatic solvents
  • Low moisture and volatile content

These characteristics ensure maximum consistency and compatibility with sophisticated formulations and performance-focused industries.


Why Choose Gilsonite Grade A?

Key Benefits

  • Superior performance under high-pressure, high-temperature conditions
  • Uniform particle distribution for predictable formulation behavior
  • Improved bonding, sealing, and waterproofing characteristics
  • Minimal impurities for cleaner processing and reduced by-products
  • Reliable global availability with scalable supply

Applications of Gilsonite Grade A in Industry
