Caprolactam
CAS NO.: 2-105-60-2
EINECS NO.: 203-313-2
H.S. CODE: 2933710000
FLASH POINT: 125 °C
MF:C6H11NO


Features:
Caprolactam is colorless in liquid state and white in solid(flake), with a slippy touch and special smell. It is hydroscopic, and apt to dissolve in water and benzene. When it is heated, a polymerization will take place and it will conbust in fire.
Melting point : 68℃~69℃
Boiling point : 270℃ (at 760mmHg)
Density : 1010kg/m³ (at 85℃)

Application:
Caprolactam is largely used in producing nylon 6 which can be further processed into:
——Textile yarn: for making textile products, such as clothing, carpet, blanket and woven decoration materials etc.
——Technical yarn: for making tire cord fabric, canvases, conveying belts, fishing nets, ropes and parachutes etc.
——Engineering plastics: for making parts for machines, automobiles, electrical appliances and electronic products etc., and the material for making engineering pipes, bars, plates, and tapes etc.

Packing:
Packed in bags made of two layers of kraft paper with a PP woven bag in between and lined with PE film. Netweight of a full bag: 25kg.

Transportation and storage:
It must be stored in dry, clean storehouse to prevent from moisture, and isolated from heat and fire sources. Outdoor storage is forbidden. Do not transport it together with other hydroscopic stuffs, oxidants, acids and alkalis etc. Handle with care and do not damage the bags.

Storage period: 3 months.
