Grade Selection
Find your grade
Two ways in: start from your end product, or from the viscosity tier your process calls for. Every route points to a recommended series — our lab confirms the exact grade from your target spec.
By Viscosity / Process
Grade numbers encode the viscosity tier — low number, low viscosity. Exact viscosity windows ship with the TDS.
Low viscosity · M5–M30
Short-chain, fast-reacting grades for MCC and low-DP ether / ester routes.
Recommended: M Series →Viscosity window: Ask for latest specMedium viscosity · M50–M200
The workhorse tier for construction-grade HPMC / HEMC and general etherification.
Recommended: M Series →Viscosity window: Ask for latest specHigh viscosity · M400–M1000
High-DP grades for high-viscosity ethers and demanding specialty formulations.
Recommended: M Series →Viscosity window: Ask for latest specSheet pulp
Board-format feedstock with controlled DP for acetate, viscose and sheet-fed lines.
Recommended: Specialty Cotton Pulp →DP range: Ask for latest specRecommendations reflect common industry practice — send your target specification and our technical team confirms the matching grade.
Product Lines

X Series — Nitrocellulose
High-alpha-cellulose pulp with low impurities and consistent nitration performance for reliable nitrocellulose production.
View Specs →
C Series — Cellulose Acetate
Cotton-linter based grades engineered for high-purity downstream uses where feedstock quality is decisive.
View Specs →
Specialty Cotton Pulp
Sheet-form cotton pulp for processes requiring board-format feedstock and controlled degree of polymerization.
View Specs →Grade Naming
How to read our grade names
Grade numbers encode viscosity tier — no arbitrary marketing names. Exact viscosity windows for each grade are shown on the TDS.
Prefix M — full viscosity line
The M prefix identifies our standard refined cotton range. The number that follows is the viscosity grade index: the larger the number, the higher the viscosity tier.
M5 — low viscosity tier
Grades such as M5, M15 and M30 sit at the low-viscosity, low-DP end, selected by processes calling for shorter cellulose chains and faster reaction kinetics.
M1000 — high viscosity tier
Grades such as M400, M650 and M1000 sit at the high-viscosity, high-DP end, covering the upper steps of the range for high-molecular-weight downstream routes.
X / C — specialty prefixes
X denotes specialty-process refined cotton grades with tight viscosity control; C denotes high-purity cotton-linter grades. Grade sheets are available on request.
