Product Info
What is CMC FVH9?
CMC FVH9 is a food-grade, high-viscosity cellulose gum used primarily as a thickener, binder, and stabilizer in foods and beverages.
How is CMC FVH9 made?
| Step No. | Production Stage | Key Action | Control Point & Note |
|---|---|---|---|
| 1 | Alkalization | Reacting purified cellulose (wood pulp or cotton linter) with a sodium hydroxide (NaOH) solution. | The concentration of NaOH, temperature, and reaction time are critical. This step swells and activates the cellulose, making it receptive to the etherification agent. |
| 2 | Etherification | Adding a carboxymethylating agent, typically Sodium Monochloroacetate (SMCA), to the activated alkali cellulose. | This is the core reaction. The ratio of SMCA to cellulose determines the Degree of Substitution (DS), a primary characteristic of CMC. Strict temperature control is essential to ensure uniform reaction and prevent by-product formation. |
| 3 | Purification (Washing) | Neutralizing excess alkali and washing the crude CMC with an aqueous alcohol solvent (e.g., ethanol/water) to remove salts and by-products. | The number of washing cycles and solvent composition directly impact the final product purity (assay). For food-grade CMC FVH9, purity must be at least 99.5% to meet regulatory standards. |
| 4 | Drying | Removing the solvent and water from the purified CMC product, typically using a flash dryer or rotary dryer. | Final moisture content must be controlled (typically <10%) to ensure product stability and flowability. The drying temperature must be managed carefully to avoid product degradation or discoloration. |
| 5 | Milling & Sieving | Grinding the dried CMC to a fine powder and then sieving it through specific mesh screens. | Particle size distribution is a key parameter that affects the product's dissolution rate and handling. The sieving process ensures product uniformity and removes any oversized particles. |
| 6 | Quality Control & Packaging | Conducting comprehensive laboratory analysis on the final powder and packaging the approved product into sealed, multi-layer bags. | Each batch is tested for critical specifications: viscosity, purity, pH, Degree of Substitution (DS), and microbiological limits. The product must meet all food-grade standards (e.g., FCC, E466) before being released. |

Applications & Usage
Common Applications:
No application data available.
Mechanism of action:
| Parameter | CMC FVH9 |
|---|---|
| Functional Category | Thickener; Viscosity Modifier; Stabilizer; Water Binding Agent |
| Key Ingredients | Sodium Carboxymethyl Cellulose (Cellulose Gum, E466) |
| Mechanism of Action | Hydrates rapidly in aqueous systems. The anionic carboxymethyl groups along the cellulose backbone cause electrostatic repulsion, forcing the polymer chain to uncoil and extend. These extended chains entangle, forming a three-dimensional network that immobilizes water molecules, thereby significantly increasing viscosity and building structure. |
| Application Effect in Product | Provides high viscosity and rich mouthfeel in liquids (e.g., beverages, sauces); prevents syneresis by binding free water; stabilizes emulsions and suspensions (e.g., dressings); inhibits ice crystal growth in frozen desserts; improves moisture retention and volume in baked goods. |
Comparison:
| Product Name | Category/Type | Key Features | Strengths (vs peers) | Weaknesses (vs peers) | Best Use Cases | Why Choose |
|---|---|---|---|---|---|---|
| CMC FVH9 | Rotary-Wing Flight Helmet | Lightweight composite shell, modular design (NVG, comms), improved center of gravity, optional maxillofacial shield. | Very lightweight and well-balanced, significantly reducing pilot neck strain and fatigue; highly modular platform. | Newer system with a smaller operational footprint and logistics chain than incumbent helmets; potentially higher cost. | Long-duration missions, special operations, crews prioritizing comfort and modularity for advanced equipment integration. | To minimize pilot fatigue and maximize adaptability with a modern, purpose-built lightweight design. |
| Gentex HGU-56/P | Rotary-Wing Flight Helmet | Kevlar composite shell, dual visor system, customizable TPL/SCL liners, widespread compatibility. | Extremely proven and reliable (decades of service), robust global logistics and parts support, lower acquisition cost. | Heavier than modern composite helmets, less optimized center of gravity can increase neck strain over time. | Standard military aviation, large fleet operations, missions where cost and proven reliability are the top priorities. | For a battle-tested, cost-effective, and universally supported standard helmet system. |
| Thales Scorpion HMD | Helmet Mounted Display System | Full-color symbology and video display, motion tracking for targeting/navigation, can be fitted to existing helmets. | Provides unparalleled situational awareness with integrated flight/sensor data; enables "eyes-out" operation. | Significantly higher cost and complexity; adds weight and requires specific aircraft integration. | Attack, reconnaissance, and advanced utility helicopters with integrated sensor suites requiring enhanced targeting and data display. | When the mission requires the highest level of integrated digital information and targeting capability presented to the pilot. |
| Alpha 900 Rotary Wing Helmet | Rotary-Wing Flight Helmet | Lightweight aramid/carbon fiber shell, multiple liner options, quick-release communications and visor systems. | Excellent balance of light weight, protection, and comfort; highly regarded and used extensively outside of US DOD. | Less integrated into the US military logistics chain compared to the HGU-56/P. | Military and civilian SAR, EMS, and law enforcement aviation; European military forces. | For a proven, high-performance alternative to US-centric designs, with a strong focus on pilot comfort and fit. |
| LIFT Airborne H-VIS | Rotary-Wing Flight Helmet | Carbon fiber composite shell, BOA dial-fit system, modular accessory mounts, multiple visor options. | Extremely lightweight and stable due to the modern fit system; excellent ventilation and comfort. | Primarily focused on civilian/paramilitary markets; less established in frontline military roles compared to peers. | Search and Rescue (SAR), HEMS (air ambulance), law enforcement, and general aviation where comfort is paramount. | For maximum comfort, stability, and minimal weight in non-combat or specialized para-public roles. |
