Our Agricultural Grade Caprolactam Ammonium Sulfate is a high-efficiency compound nitrogen fertilizer, refined from by-products of caprolactam production. This product combines the stability of ammonium sulfate with the special benefits of caprolactam
derivatives, providing an innovative fertilizer solution for modern agriculture.

Key Features:
* High nitrogen content (≥21%), providing essential nutrients for crop growth
* Contains sulfur (≥24%) to meet crop sulfur requirements
* Unique organic components improve soil structure
* Excellent water solubility with high absorption rate
* Low chlorine content, suitable for chlorine-sensitive crops
* Neutral pH, does not cause soil acidification
(1)Most of caprolactam is used to produce polycaprolactam, about 90% of which is used to produce synthetic fiber, and 10% is used as plastic, which is used to manufacture gears, bearings, pipes, medical devices, electrical and insulating materials. It is also used in coatings, plastic agents and a small amount of lysine synthesis.
(2)It is mainly used to make caprolactam resin, fiber and artificial leather, and also used as pharmaceutical raw materials.
