Degree of polymerization, reactivity and cost compared — and the processes where cotton-based cellulose is not optional.
This comparison guide is being prepared by our technical team. The full article will cover DP distributions, α-cellulose fractions, reagent consumption behavior and end-product viscosity ceilings, with a side-by-side view of where refined cotton is technically required versus where wood dissolving pulp is a workable alternative.
Full article coming soon. In the meantime, send us your derivative process and target spec — our engineers will walk you through the feedstock choice for your line.
TechnicalA buyer's guide to refined cotton viscosity grades: low, medium and high viscosity ranges, how viscosity relates to degree of polymerization, and what alpha-cellulose, ash and iron mean for downstream etherification and esterification.
