UNIPRENE®…At A Glance

What Is Uniprene®?Uniprene® is a specially designed thermoplastic vulcanizate (TPV).

It performs like cured EPDM with the feel of thermoset rubber…butprocesses with the ease and speed of a thermoplastic olefin (TPO).Uniprene® TPVs have mechanical and recovery properties comparableto most vulcanized elastomers and are superior in performance to mostthermoplastic elastomers (TPEs).

What Are The Material Characteristics Of Uniprene®?• High elastic recovery.• Non-hygroscopic characteristics, eliminating the need for

predrying under normal conditions.• Light natural color. Excellent whitening index permitting

easy precoloring or recoloring and reduction of colorloading requirements.

• Wide service temperature range.• Excellent compression set at room and elevated temperatures.• Recyclability.• Easy processability on standard thermoplastic equipment.

What Grades Of Uniprene® Are Available?Standard Uniprene® TPVs are available in a hardness range of

35 Shore A to 50 Shore D. However, both harder and softer grades canbe formulated to meet your specific application.

All Uniprene® grades are available in natural (colorable) and black.Uniprene® can also be provided in custom colors, matched to meetmost needs.

The performance benefits of Uniprene®

Uniprene® TPVs are composed of a fully cross-linkedelastomeric phase finely dispersed in a thermoplasticmatrix. The result is functional performance similar tothe high elastic recovery of vulcanized rubber but withthe processability of plastic.

Because Uniprene® compounds are cross-linkedelastomers, soft grades provide a linear stress-strainrelationship, thereby providing rubber-like performancecharacteristics. Low compression sets create the opportunityfor replacing thermoset rubber in applications such asweatherstripping, gaskets and seals.

Uniprene® provides better retention of shapeupon ejection than conventional TPEs, especiallyon larger injection molded parts. Because of lowerspecific gravity, part weight reductions can beachieved versus thermoset rubbers. A wideservice temperature range of -60 degrees Cto +135 degrees C makes Uniprene® suitablefor performance under many static anddynamic conditions as well as applicationsrequiring tight sealing.

The aesthetic benefits of Uniprene®

The light natural hue of Uniprene® results in bright,vibrant colors. Because Uniprene® exhibits less inherentyellowness than most commercial TPVs, lower loading ofpigments or color concentrates are required for coloring.

The combination of aesthetics and functionality canprovide improvements in product appearance, ergonomics,noise and vibration dampening. This is especially true in

soft-touch applications requiring two-shotinjection, overmolding or coextrusion.

The processing benefits of Uniprene®

Uniprene® compounds can be processedon standard thermoplastic equipment and providesizable gains in productivitycompared to thermoset

Ideal for pre-colored, “soft-touch” and engineered custom applications.

rubber compounds. Due to its non-hygroscopic nature,Uniprene® can normally be processed without the pre-drying necessary for conventional thermoplastic vulcanizates.

Because of its excellent melt strength, Uniprene®also provides good part shape retention in unsupportedblow molding and thermoforming applications.

Uniprene® is recyclable and can be reprocessedseveral times without significant property losses.

All grades of Uniprene® thermoplastic vulcanizatesare suitable for both molding and extrusion processes.Processing guidelines are available fromTeknor Apex.
