Bleached Cotton Linters

Bleached Cotton Linters (BCL)/ Cellulose Pulp is a high viscose fluffy high value fiber consists of highest proportion of cellulose with minimum amounts of non-cellulosic material as compared to other source of Cellulose like Wood Pulp. BCL a wide range of applications and they are:

  • Cotton linters pulp with medium to low viscosity used for manufacturer of Propellant Grade Nitrocellulose
  • BCL Pulp with high brightness us used for production of speciality Papers, Boards & Pads.
  • Very high to medium Viscosity Bleached cotton linters are used for manufacture of Cellulose Ethers such as CMC, PAC etc.
  • Purified cellulose for production of Industrial Notrocellulose, Cellulose Acetate & Speciality Papers.
