Description and Uses
Caprolactam, CH2CH2CH2CH2CH2NHCO, is a solid material composed of white flakes. Caprolactam is soluble in water and has a specific gravity (in a 70% solution)of 1.05, which is heavier than water. It may also be encountered as a molten material. Caprolactam is toxic by inhalation, with a TLV of (vapor) 5 ppm in air and (dust) 1 mg/m3 of air. The primary uses are in the manufacture of synthetic fibers, plastics, film, coatings, and polyurethanes.
Monomer for manufacture of polycaprolactam (Nylon 6) used in carpets, textiles, clothing, and tires
