Other Industrial Applications

PVC Suspension Polymerization

METHOCEL™ is an essential processing aid for the manufacture of high-quality PVC. An important characteristic of polyvinylchloride (PVC) is its ability to absorb additives, such as plasticizers, stabilizers, and pigments, quickly and in sufficient quantities. To achieve this goal, a defined level of porosity is required which is often obtained at the expense of bulk density. The balance between porosity and bulk density is a constant issue and our METHOCEL™ products create the ideal balance enabling both process and finished product quality.

METHOCEL™ Product Features	Benefits
GMP manufacturing conditions Meets food grade specifications and testing requirements for Food grade packaging	Complies with food additive requirements Allows for food contact PVC
Surface activity	Reduced interfacial tension Facilitates dispersion
Suspension agent	Particle size control Uniform particle size distribution Reduced droplet size
Film forming	Encapsulates droplets in a protective film Prevents monomer droplet coalescence
Broad range of substitution levels	Provides consistent performance Enables custom porosity (final rigid / flexible PVC)
Synergies with other protective colloids	Control grain porosity and particle size

* Most of our recommended METHOCEL™ grades for PVC applications are food grade ; please consult your account manager for more information.

METHOCEL™ Product Selection Table

Recommended Product	Viscosity (cP) (2% in water)	Porosity	Performance in Use
METHOCEL™ E50	50	High	Low density, high porosity, allows for faster blending with plasticizer (flexible PVC), low VCM residuals
METHOCEL™ F50	50	Medium	General purpose suspending agent, moderate density
METHOCEL™ K100LV	100	Low	Rigid PVC, high density, low porosity, glassy

Pulp and Paper

In paper manufacturing, it is critical that additives, fillers, and fibers are retained on the paper machine web during the de-watering process. Their use in filler retention applications has also become increasingly important due to the demand for high-opacity, lighter-weight paper and the growing cost of pulps. Our METHOCEL™ products are used in paper coating applications to deliver a range of functional benefits.

Non-charged polymers	UCARFLOC™ is used as a retention aid for pulps containing anionic electrolytes
Film forming	METHOCEL™ offers oil barrier properties in paper coating applications POLYOX™ enhances the coating load and improves paper quality

GSS Product Selection Table

Recommended Product	Functional Benefits
METHOCEL™ E	Processing aid: reduces organic contaminants from recycled paper (pitch and stickies control)
UCARFLOC™	Flocculation and paper fines retention due to high affinity for pulps and fillers (silica, clays and linins)
SCOGIN®	Paper sizing: film-former, smooth surface, improves grease and solvent resistance, reduces air porosity Paper coating: improves coating uniformity and printing, reduces coating defects
ETHOCEL™ AQUACOAT®	Moisture barrier to protect paper surface

Ice & Gel Packs

Highly viscous solutions in water are produced by addition of WALOCEL™ CRT carboxymethylcellulose or METHOCEL™ cellulose ethers at 0.5 to 5%. When formulated with freezing point depressants such as salts, glycols, or alcohol, these mixtures can be placed into suitable packs which are more or less flexible in the frozen state. Such re-useable packs can be used as ice packs for food deliveries or as cold compresses for first aid. Gel packs can also be warmed up in a water bath or microwaved.

Typical Starting Formulations

Ice Pack

Component	Amount (wt%)
METHOCEL™ K15M Food Grade	4-5%
Propylene glycol	20-40%
Water	55-75%
Preservatives and additives	quantum satis

Gel Pack (Hot or Cold)

Component	Amount (wt%)
TEXTURECEL™*	0.5 - 3
Propylene glycol	10-20
Water	80-90
Aluminum sulfate	quantum satis

Lighting

Recent advances in lighting technology, such as CFL bulbs and fluorescent lamps, require the manufacturing of phosphor slurry and premium sacrificial binders.

POLYOX™ Product Features	Functional Benefits
High binding efficiency	Clean burn-out Rheological control
Excellent solubility	Tunable viscosity across a broad range Stable viscosity across a wide pH range
Solvent compatibility	Highly compatible with a variety of dispersants and antifoams
