Applications of IONOL CP:

Polymers:
IONOL CP is used for the stabilisation of plastics, natural and synthetic rubber, waxes, synthetic and natural resins as well as for articles and mixtures which are produced from any of the above.
The stabilisation with IONOL CP starts with the production of plastics and ensures, dependent on the dosage quantity, the storage stability of the polymer raw material until processing to the finished article. 

During the processing of the polymer raw material to the final product, an additional long-term stabilisation with IONOL CP can be very effective.
The application field of IONOL CP is widespread because of IONOL CP excellent cost-efficiency ratio as well as IONOL CP almost universal application possibilities in plastics, particularly for articles requiring approval as defined by food contact legislation.

Adhesives and hot melts:
Adhesives and hot melts are also subject to autoxidative damage caused by mechanical stress, heat and light. 
IONOL CP is used for process as well as for long-term stabilisation.

Odorous substances:
In odorous substances, e.g. body-care products, IONOL CP prevents autoxidation processes which lead to undesired and unpleasant smelling decomposition products.

Foodstuffs:
In foodstuff IONOL CP decelerates the damaging effect in fats, carotenoids, vitamins as well as in further essential food constituents caused by oxidation with atmospheric oxygen.

Polyols:
Polyols are subject to oxidative damages by light and heat in the presence of oxygen due to radical reactions. 
By using IONOL CP the reactive radicals are captured and transformed into non-reactive compounds. 

The chain reaction is stopped and a further damage is avoided.
IONOL CP is used as a long-term stabiliser in order to protect the polyols during storage (e.g. before use in polyurethanes) against decomposition reactions. 
Depending on application, the optimum dosage amounts to 0.1 - 1.0 %.

Further Applications of IONOL CP:

Polyurethanes:
IONOL CP is used for polyurethanes as a processing and long-term stabiliser.
Particularly in the production of polyurethane foams, IONOL CP is more efficient than many other antioxidants. 
Due to the high temperatures which arise inside the block foams during production, partially strong scorching can occur. 

IONOL CP is very efficient and mobile, and prevents scorchingeffects. 
Hence, the production of undamaged and non-discolouring foams made possible.

Depending on the application, the optimum dosage amounts to 0.1- 1.0 php. 
According to the BfR regulations chapter XXXIX BHT is recommended as an anti-ageing agent for finished articles produced from polyurethanes.

Printing inks:
The shelf life of printing inks can be shortened by oxidation. 
Physical changes during processing may occur. 

The use of IONOL CP has a positive effect on the stability, levelling resistance as well as on the brightening and hardening properties of printing inks.
In lithographic printing IONOL CP prevents skin formation and accelerates the drying process. 
The average quantities to be employed amount to 0.5 – 1.0 %.

Uses of IONOL CP:
IONOL CP is an oil-soluble antioxidant widely used at home and abroad. 
Although IONOL CP is toxic, IONOL CP has strong antioxidant ability, good heat resistance and stability, no specific odor, no color reaction of metal ions, and low price, only 1/8~1/5 of BHA. 
Generally IONOL CP is used in conjunction with BHA, and citric acid or other organic acids as a synergist. 

China's provisions can be used for edible oil, fried food, biscuits, instant noodles, nuts canned, dry fish products, the maximum use of 0. 2g/kg. 
IONOL CP also has a certain antibacterial effect, but weaker than BHA.

Used as rubber,
Plastic antioxidant,
Gasoline, 
Transformer oil, 
Turbine oil, 
Animal and vegetable oil, 
Food and other antioxidants.
