Gilsonite Grade C
Introduction
Not all industrial applications require top-tier materials. For many projects, the focus is on cost-effectiveness, operational efficiency, and functional performance. This is where Gilsonite Grade C shines—offering a reliable, budget-friendly option for industries looking to optimize processes without sacrificing basic quality.
Gilsonite Grade C is ideal for applications with less stringent technical specifications. From mass-scale road construction to general waterproofing and insulation materials, this grade provides excellent value in high-volume, cost-sensitive environments.
What is Gilsonite Grade C?
Gilsonite Grade C is a naturally occurring asphaltite selected for its affordability and functionality in broad industrial uses. While it contains more ash and impurities than Grades A or B, it still retains many of the natural properties that make Gilsonite desirable—especially in formulations where ultra-high purity is not essential.
Key Characteristics
- Purity: 60–70%
- Ash content: 15–25%
- Medium solubility in hydrocarbons
- Softening point: ~160–180°C
- Affordable pricing for bulk consumption
Benefits of Gilsonite Grade C
- ✅ Low-cost material for budget-conscious projects
- ✅ Functional performance in general applications
- ✅ Easy availability in high volumes
- ✅ Compatible with traditional asphalt, bitumen, and binders
- ✅ Eco-friendlier than synthetic alternatives in some uses
While not suitable for high-spec chemical or drilling applications, Grade C Gilsonite is a practical choice for many industries seeking affordable solutions for sealing, binding, and enhancing materials.
Applications of Gilsonite Grade C
Road Construction and Asphalt
Gilsonite Grade C is commonly used in road construction projects with standard performance needs. It enhances:
- Pavement stiffness for light to medium traffic roads
- Resistance to water ingress
- Adhesion between aggregates and binder
- Base-level aging and oxidation resistance
It is also widely used in developing regions or in rural road networks where performance demands are moderate, but cost control is critical.
Bituminous Compounds
Used in formulations such as:
- Asphalt primers
- Emulsion mixes
- Patching materials
- Driveway and walkway surfacing
It provides cohesive strength and waterproofing in economically optimized road and roofing products.
Waterproofing and Insulation
In construction and building materials, Gilsonite Grade C contributes to:
- Waterproof coatings for non-critical applications
- Protection layers in underground foundations
- Thermal insulation panels and filler compounds
- Pipe coatings for general protection
It is especially favored in hot-applied waterproofing compounds and low-cost bituminous mastics.
Industrial Fillers and Additives
Due to its affordability, Grade C Gilsonite is used as:
- A filler in rubber and plastic industries
- A binding aid in low-end construction chemicals
- An extender in roofing felts and protective wraps
It helps reduce formulation costs while maintaining basic mechanical properties.
Packaging and Formats
Gilsonite Grade C is available in various industrial forms to suit manufacturing and blending processes:
Formats Available
- Lump – For bitumen processing and insulation compounds
- Granules – Ideal for asphalt plants and waterproofing systems
- Powder – Available in lower mesh sizes for fillers and simple mixes
Packaging Options
- 25 kg polypropylene bags
- 500–1000 kg jumbo bags
- Bulk container shipments for high-volume buyers
Who Should Use Gilsonite Grade C?
Gilsonite Grade C is the smart choice for:
- Contractors managing budget-restricted infrastructure projects
- Manufacturers producing mass-volume waterproofing products
- Asphalt companies looking for base performance modifiers
- Exporters seeking a low-cost product for emerging markets
