Defence & Nitrocellulose Industry
Parason manufactures disc refiners and cotton linter processing equipment for propellant-grade nitrocellulose production — achieving 99% alpha-cellulose purity for defence applications.
Cotton Linter Processing Equipment for Nitrocellulose Production
Parason provides disc refiners and complete cotton linter processing systems for nitrocellulose manufacturers. Our equipment enables the alkaline cooking, bleaching, and refining stages that achieve 98-99% alpha-cellulose purity — the critical specification for propellant-grade nitrocellulose.
With decades of refiner manufacturing expertise, Parason develops specialized plate patterns for cotton linter fiber development. Our systems support both ECF (Elemental Chlorine Free) and TCF (Totally Chlorine Free) bleaching processes, delivering pulp with 88%+ ISO brightness while maintaining cellulose fiber integrity.
