Bleached Cotton Linters Bleached cotton linters are cotton linters that have been subjected to a bleaching process to remove any remaining impurities and achieve a uniform white color. Bleaching is done to improve the quality and appearance of the cotton linters and to make them suitable for use in high-end applications, such as currency, security papers, and other specialty papers. |

We provide 3 types of bleached cotton linters as per the customer’s requirement.
M1000: Highly purified cellulose for production of Industrial Nitrocellulose, Cellulose Acetate & Speciality Papers. X15: Cotton linters pulp with medium to low viscosity used for manufacturer of Propellant Grade Nitrocellulose.
X30 : Very high to medium Viscosity Bleached cotton linters for manufacture of Cellulose Ethers such as CMC, PAC, Explosive Grade Nitrocellulose, etc.
