Products Description
Caprolactam-Grade Ammonium Sulfate Fertilizer Technical Profile
Derived as a high-purity byproduct from nylon-6 (polycaprolactam) manufacturing processes, our caprolactam-grade ammonium sulfate (NH₄)₂SO₄ meets stringent industrial purity standards while delivering superior agricultural performance. This dual-nutrient fertilizer contains 21% nitrogen (in ammonium form) and 24% sulfur (as sulfate), making it particularly effective for sulfur-deficient soils and high-value crops.
