Is Caprolactam the same as Nylon 6?

No. Caprolactam is the cyclic monomer or precursor identified by CAS 105-60-2 and is polymerized into polyamide 6. It is not the finished Nylon 6 polymer product, so the quotation should distinguish monomer supply from polymer or compound supply.

Is Caprolactam supplied as flakes or molten liquid?

Both forms are traded. Flake Caprolactam is packed in moisture-resistant bags, while molten material requires a heated dedicated tank system. State the physical form, delivery temperature, quantity and receiving capability because the two delivery modes are not interchangeable without logistics changes.

Which specifications define polymer-grade Caprolactam?

Agree solidification point, water, color, permanganate index or number with its method, volatile bases, acidity, alkalinity, absorbance at 290 nm, ash, iron and insoluble matter. Nylon-6 production requires a complete impurity profile, so compare methods and limits rather than assay alone.

What are the key physical properties of Caprolactam?

Caprolactam has molecular formula C6H11NO and molar mass about 113.16 g/mol, with melting/solidification point around 68-70 C and boiling point about 267-270 C. Flake bulk density is commonly about 600-700 kg/m3, while the solid or melt density is near 1.02 g/cm3.

How should Caprolactam be stored and handled?

Store flakes in a cool, dry, well-ventilated area in tightly closed moisture-barrier packaging away from strong acids, oxidizers and heat. Molten Caprolactam needs maintained temperature and nitrogen protection where specified. Review the current safety information and process safety requirements before transfer.
