The Flexibility to Provide Customized Solutions
Daikin can provide DAI-EL fluoroelastomer in exactly the form that you need: As a base
polymer (gum), a cure incorporated precompound or a full compound. So whether you mix your own
compound or have someone else do it, consider the benefits of using our custom compound facility.
Perfect Chemistry
All of our manufacturing, research and development, sales and marketing teams are
linked by a common pursuit: To better serve our customers so our customers can better serve theirs.
At Daikin, we strive to be proactive instead of reactive. We try to learn all we can about our

Safe Handling
1. Compounding agent and facility: The common fillers and facilities for commodity rubber can be
used for DAI-EL. The mixing mill needs to be cooled. Finely divided metallic powder or filler,
such as aluminum and magnesium, or amine compounds of more than 10% should not be used as compounding agents for DAI-EL because such materials are known to decompose vigorously at
moderately elevated temperature.
2. Storage and remixing: Store the compound in a tightly closed package in a cool and dry place.
Another milling before use is recommended when the compound is left for more than three days. Too
tight a nip between the rolls in the mixing mill may cause scorching. Be sure to cool the rolls well
whenever the compound is milled with tight nip.
3. Molding/Curing: The work area should be adequately ventilated at all times because a
small amount of toxic gases (e.g. HF, acetone, methanol, acetaldehyde, methyl iodine and carbon
monoxide) may be evolved during curing.
4. Material handling: A slight amount of hydrogen fluoride vapor may be produced during the use
at high temperatures(above 200ºC). The room should be well ventilated. Do not smoke in the work
area as harmful vapors may be inhaled when cigarettes are exposed to the powder of DAI-EL. After
handling the powder of DAI-EL, knock off any dust from your hair or clothing and wash your face and
hands thoroughly before smoking.
5. Disposal: Do not incinerate DAI-EL as this can produce harmful vapors. Disposal should be
done in accordance with local laws and regulations.
