uPontTM Surlyn? 9910
Description
Product Description DuPontTM Surlyn? 9910 thermoplastic resin is an advanced ethylene/methacrylic acid
(E/MAA) copolymer, in which the MAA acid groups have been partially neutralized
with zinc ions. The amount of MAA and neutralization levels for this grade result in a
combination of high clarity, stiffness and abrasion resistance, along with a very low
melt flow index of 0.7. The resin can be extruded, blow molded, and injection molded.
In golf ball covers, it provides excellent durability, especially when blended with other
grades of Surlyn? made with different cations. It complies with the provisions of U.S.
Food and Drug Administration (FDA) Title 21 Code of Regulations 177:1330.

Processing Information
FDA Status Surlyn? industrial resins are available that comply with US FDA 21 CFR 177.1330.
For more information contact your DuPont sales office.
Safety & Handling Surlyn? 9910 as supplied by DuPont is not considered a hazardous material. As with
any hot material, care should be taken to protect the hands and other exposed parts
of the body when handling molten polymer. At recommended processing
temperatures, small amounts of fumes may evolve from the resins. When resins are
overheated, more extensive decomposition may occur. Adequate ventilation should
be provided to remove the fumes from the work area. Disposal of scrap presents no
special problems and can be by landfill or incineration in a properly operated
incinerator. Disposal should comply with local, state, and federal regulations. Resin
pellets can be a slipping hazard. Loose pellets should be swept up promptly to
prevent falls.
For more detailed information on the safe handling and disposal of DuPont resins, a
Product Safety Bulletin and OSHA Material Safety Data Sheet can be obtained from
the DuPont Packaging Products sales office serving you.
