* The expert panel made no distinction between glass ionomer resin
modified sealant and resin sealants in the guideline.
* Enhanced capabilities for DuPont Surlyn ionomer resin
and Vamac ethylene acrylic elastomers from DuPont Performance Elastomers and upgrades to improve energy efficiency at DuPont's Sabine operation in Orange, Texas.
EasyUp adds easy opening to the strength of collation shrinkwrap because of a specific development based on a Surlyn /PE combination that offers high tear-resistance lengthwise and low transverse tear strength based on the molecular structure of the DuPont ionomer resin
and a patented extrusion process.
That's such a strong selling point for Surlyn ionomer resin
that its manufacturer, DuPont Packaging and Industrial Polymers, Wilmington, Del., has put together a software package touting it.
An ionomer resin
was used to compatibilize the polypropylene-nylon 66 interfaces.
The Spanish company LMG Suner SA has used a laminate of co-extruded OPP film, metallized Mylar polyester film and a seal layer of co-extrusion Surlyn ionomer resin
to develop a high performance flexible packaging structure for cocoa powder.
In a previous paper (1), the morphologies of a ternary blend of nylon 66 and polystyrene in a polypropylene matrix with and without compatibilization by an ionomer resin
(for nylon 66 and polypropylene) and a styrene-block-ethylene-co-butylene-block-styrene copolymer (for polystyrene and polypropylene) were investigated by transmission electron microscopy.
Others types of specialty resins include ion-exchange resins and ionomer resins
. In water treatment, ion-exchange resins are used for the removal of certain metals from industrial and municipal wastewater.
Cyclic olefin/PE films can compare favorably in both cost and performance to packages made with nylon or ionomer resins
, as well as PE-only films.
Surlyn ionomer resins
provide low-temperature impact properties in nylon 6 and nylon 66.
