Specifications

The heart of our Leuna production is Caprolactam, the most indispensable intermediate in the production of Nylon 6. Caprolactam is the core of our production. To insure the most pure and high-quality production possible, our Caprolactam quality is monitored and tested through a Caprolactam-specific gas chromatic (GC) analytical system.

We offer Caprolactam both in liquid form and in flakes (bulk density: 520 ± 10 kg/m³). The storage temperature should not exceed 45 °C.

Transport & Packaging:

Caprolactam is transported in a liquid state at temperatures of 75-90 °C under a N2 atmosphere (O2-content less than 50 ppm) in thermally insulated heatable rail tank cars, containers and road tank cars made of stainless steel. Solid Caprolactam in the form of flakes is packed in water impermeable polyethylene bags of 25 kg. The polyethylene bags are brought to shipping stretch-wrapped on pallets with a net weight of 1.00 / 1.25 / 1.50 mt. Normally 40 feet containers (maximum load 24 mt) are used for transportation overseas. Solid Caprolactam should be protected from direct sunlight and humidity.

Application

Caprolactam is mainly used for the production of polyamide 6 pellets as well as for N-Methylcaprolactam
