          Vistalon 7602
Vistalon 7602 EPDM is a high ENB polymer with low ethylene content and a medium Mooney viscosity. It has a broad molecular weight distribution for excellent compounding and processibility.

Vistalon 7602 is designed for extruded applications like weatherseals and glazing seals that require a fast cure tate and good compression set. It may also be used in molding applications requiring fast cure rates.

          Vistalon 8800
Oil-extended EPDM grade of high molecular weight with a low ethylene content and high diene level. Developed as a sponge grade to provide short mixing cycles and outstanding dispersion for compounding ultra soft profiles.

          Vistalon 1703P
Designed for wire and cable insulation, this EPDM grade's low level of VNB diene, combined with the need for lower curative levels, results in an exceptionally low dissipation factor during aging compared to other leading dienes. Has and exceptional retention of physical properties. Sold in pellet form.

          Vistalon 2502
Vistalon 2502 is an amorphous EP(D)M grade specially developed for molded goods and extruded profiles, with the following features:

• Low Mooney, low ethylene, medium diene EP(D)M polymer.
• ExxonMobil proprietary metallocene based technology allows for precise control of the molecular composition.
• Offers benchmark low-temperature properties with high cure rate and high cure state.
• Compared with present Vistalon 2504, Vistalon 2502 offers a lower ethylene content with similar molecular weight and slightly increased diene content.

          Vistalon 2504 (EVA Release)
          Vistalon 2504 (PE)
This low-viscosity EPDM is recommended for molded goods, sponge, extrusions and low voltage electrical insulting materials. It is fast-curing, easy processing, and exhibits ozone heat, weather, sunlight and chemical resistance. It has good low temperature flex, good resilience, and low compression set.

          Vistalon 3702
A metallocene catalyst based ethylene-propylene-diene terpolymers designed primarily for roof membrane applications. This polymer, a lower molecular weight analog of Vistalon 9301, has a low level of unsaturation, a high molecular weight, and a low level of crystallinity. Its molecular architecture has been specifically tailored to facilitate formulation, processing and conversion into thermoset roof membrane compounds, and is used in low slope flame retardant (LSFR) membrane applications.

          Vistalon 5601 (Pellets)
High Mooney viscosity metallocene EPDM for molding and extrusion. Offers superior processing compared to typical narrow MWD grades for smooth and fast extrusions, improved mixing, mill handling and physical properties. Develops very high tensil strength during curing. Applicable for industrial and automotive hoses, extruded profiles and molding. Fast curing, with improved oil aged retention and cure bloom in compounds.

          Vistalon 6505 (PE)
Intermediate Mooney viscosity, very fast curing EPDM. Can be blended and covulcanized with most other commonly used elastomers. Has excellent comopression set and ozone resistance. Has good heat resistance, excellent adhesion to brass and polyurethane coatings. Used in sponge, gasket and molded goods. Performs as an antiozonant for high-unsaturation rubbers.

          Vistalon 6602
Vistalon 6602 is designed for general purpose dense profile extrusions and extruded hose applications. Its amorphous structure, with a high molecular weight and fast cure rate, makes it efficient for continuous vulcanization operations, as well as molding applications, while providing for improved elasticity at low (-20 C) and high temperatures.

Vistalon 6602's high and relatively broad molecular weight, combined with a medium diene content, makes for easy compounding and processing to provide for high extrusions rates and smooth surface aspects. Compared to bimodal Vistalon 7500, Vistalon 6602 has a higher cure state and faster cure rate (even with a lower ENB content), while having similar physical properties, with higher tear resistance. Vistalon 6602 also has a higher compound Mooney viscosity, due to its narrower MWD (lower MRA value), resulting in:

• Higher elasticity at high deformation speed (extrusion)
• Lower elasticity at low deformation rate

          Vistalon 7001 (Pellets)
Intermediate Mooney viscosity, fast curing and fast extruding, tailored MWD high ethylene EPDM. Used in many applications including hose and tubing, electrical insulation, thermoplastic polyolefins, weatherstrip and molded goods.

          Vistalon 7500
Fast curing grade recommended for molded and extruded goods application. Provides consistant quality of mixed compounds, with improved productivity of mixing, extrusion and molding.

          Vistalon 8600
High molecular weight and very fast curing EPDM in especially suited for sponge applications. Also recommended for use in molded or extruded products applications.

          Vistalon 8731
A polymer with a broad molecular weight distribution, moderate branching and low diene content, with low level of ionic impurity, for medium and low voltage electrical compounds. The branched architecture of this grade provides easy processing and smooth extrusions. The relatively low diene content provides excellent heat-aging properties.
