Sodium Grade Foundry Clay Casting Additives Binding Capacity Bentonite for Iron Casting

Sodium Grade Foundry Clay Casting Additives Binding Capacity Bentonite for Iron Casting. High Wet Compressive Strength: Provides sufficient wet strength to prevent sand mold deformation during transportation and boxing. Excellent Thermal Stability: Prevents adhesive film failure under high-temperature molten metal, reducing sand flushing defects. High Reusability Rate: Low 'dead clay' formation rate significantly reduces per-unit bentonite consumption. Superior Breathability: Proper particle size ensures mold permeability and easy shake-out for cleaner casting surfaces. Proven Manufacturer: Source manufacturer with over 15 years experience, self-operated mining, and 5000+ tons annual capacity. Flexible Packaging Options: Available in 25kg woven bags or 1-ton ton bags to optimize handling and reduce costs. Global Export Experience: Products exported to over 60 countries including Southeast Asia, Middle East, and Europe. Strict Quality Control: Full chain control from mining to processing with lab testing and support for third-party retesting.
