Our hearts beat for Caprolactam
When we talk about chemicals, we talk about our passion for one specific chemical first.
The heart of our 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).
Apart from continuous process monitoring and final testing of further quality parameters, a Caprolactam specific gaschromatographic (GC) analytical system is used for trend examinations. This examination method permits the identification of trace impurities of type and quantity.
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.
The storage temperature should not exceed 45 °C.
