Santoprene™ brand thermoplastic vulcanizates (TPVs) are a series of high-performance elastomers which combine the desirable characteristics of vulcanized rubber, such as flexibility and low compression set, with the processing ease of thermoplastics. Fitting into the mid-range cost and performance spectrum of both thermoplastic and thermoset rubbers, Santoprene TPV is accepted for a broad range of industrial and consumer product applications.
Its unique combination of material properties and processing ease permits the processor to achieve such critical goals as lower production costs, consistent quality and improved production performance. Santoprene TPV can be processed on standard thermoplastic equipment. It can be injection molded, extruded, blow molded and thermoformed with the efficiency and economy associated with thermoplastic materials. In addition, clean scrap from these operations can be reprocessed.
Santoprene TPVs have environmental resistance comparable to general purpose EPDM rubber compounds, while fluid resistance is comparable to general purpose polychloroprene rubber compounds; a unique combination that lends itself to a broad range of applications. Its unmatched colorability, feel and aesthetics open new design opportunities in consumer applications.
Performance through heat and cold. Parts made from Santoprene TPV offer a constant service temperature range from -60 to 135°C (-81 to 275°F) with no cracking or tackiness. Excellent heat aging combines with resistance to oil and grease for outstanding durability.
Durability for the tough jobs. Santoprene TPV has excellent resistance to cut growth while flexing, high tear strength and excellent resistance to fatigue, and good resistance to many acids, bases and aqueous solutions.
Broad range of flexibility. Flexibility of Santoprene TPV ranges from supple, conformable 35 Shore A to tough, durable 50 Shore D. General purpose grades are suitable for most applications, and FDA-compliant, NSF-listed and medical grades are also available. Flame retardant grades meet Underwriters Laboratories requirements. These grades have UL 94 V-0 or UL 94 HB ratings.
Easier design for complex parts. Design tolerances can be two to three times more precise than with EPDM or polychloroprene rubber. Design parts with thick or thin walls; simplify multi-part designs; eliminate metal inserts. Create dual durometer parts from two hardness grades.
