IONOL 220 AH

IONOL 220 AH is dust-free version of IONOL 220, which significantly improves the handling properties of the products.
IONOL 220 AH is a non-staining antioxidant from the group of sterically hindered phenols.
Due to IONOL 220 AH low thermal volatility, IONOL 220 AH is especially suitable for oils exposed to high operating temperatures for a long time.

Molecular Weight: 424.659

IONOL 220 AH is FDA approved for some related applications.
The main applications of IONOL 220 AH are lubrication, stabilization of industrial oils such as turbine, transformer and hydraulic oils.
Other applications of IONOL 220 AH are adhesives, petroleum hydrocarbon resins and polyolefins.

IONOL 220, IONOL 103, IONOL 135 and IONOL 99 are highly effective antioxidants for multigrade Iubricants, automatic transmission fluids, differential fluids and turbine oils.

Also IONOL antioxidants have shown to increase the useful life of many industrial oils, reducing equipment downtime.
Applications include hydraulic fluids, transformer oils, spinning oils and metal rolling and cutting fluids.

IONOL antioxidants are excellent stabilizers for all grades of kerosene based Jet A1 fuel for civil and military use.
The concentration needed to protect and stabilize aviation fuels is also defined by these international specifications.
For example, DERD 2494 specifies an addition level in the range of 17.0 – 24.0 mg/L for hydrotreated fuels.

Uses of IONOL 220 AH:

Lubricants:
The continual development and improvement of the internal combustion engine has made increasing demands on Iubricants.
Increasing Crankcase oil temperatures and increasing longevity of vehicles in general require ever higher performance and stability from lubricating oils to prevent oxidation.

Oxidation contributes to piston ring sticking, formation of sludge within the oil, and an overall breakdown of the viscosity characteristics of the lubricant.
As free radical scavengers, one IONOL molecule can inhibit and help prevent the oxidation of many oil molecules, extending the useful life of lubricants and transmission fluids.

Polymer, Elastomers & Rubbers:
Oxidation is an important limiting factor in all thermoplastics and thermosetting resins.
IONOL 220 AH effects include adverse colour change, loss of flexibility, loss of tensile strength and elongation, reduced impact resistance, cracking and other surface deterioration.
Oxidation can also affect the molecular weight of a polymer, which in turn affects IONOL 220 AH other properties.

The oxidation of latex and rubber compounds can have different effects, depending on the type of polymer involved.
Problems include adverse colour changes, loss of flexibility, loss of tensile strength and reduced impact resistance, ageing, cracking and other surface deterioration.

IONOL products are widely used in polyols for flexible polyurethane foams, where IONOL 220 AH protects the polyol during production and long-term storage, as well as preventing scorching during the formation of the polyurethane foam.
Furthermore, IONOL products are also used in the production of colourless stabilized polyolefins as well as PVC and PVB films.

IONOL antioxidants are widely used in most natural and synthetic lattices and rubbers.

Biodiesel:
The IONOL BF range – 100% active, no harm approved stabilizers with superior performance.

In every phase of IONOL 220 AH lifecycle, from manufacturing to storage to combustion in the engine, biodiesel is subjected to oxidative influences.
The process starts with degradation reactions that cause undesired polymers, aggressive acids and peroxides.
Due to IONOL 220 AH natural composition, biodiesel ages a lot faster than fossil diesel and IONOL 220 AH use-by date is very often exceeded by the time the biofuel finally makes IONOL 220 AH to the end-user.

The international biodiesel norms, (e.g. EN 14214 or ASTM D 6751) demand the adherence to the specified oxidation stability.
The global specifications for fossil diesel (e.g. EN 590 or ASTM D 975) clearly prescribe that only in-spec biodiesel may be blended with fossil diesel.

Leather, Coatings and Inks:
During the process of tanning, fat is dissolved from the animal skin.
Further on in the process, the “wet-blue” has to pick up fat again.

These fats, made from different native fats, are called fat liquors.
IONOL Technical Grade, IONOL CPC or IONOL 135 are used to stabilize the feed stock of the fat liquors.

The addition of either IONOL Technical Grade, IONOL CPC or IONOL 135 helps maintain overnight stability, reduce run-resistance and improve gloss and hard drying properties in most general-purpose printing inks.
IONOL Technical Grade or IONOL CPC in lithographic inks also prevents skin formation and even promotes drying.
