Santoprene™ | Zatkoff




Santoprene™ is a crosslinked thermoplastic elastomer. It processes as a plastic, yet performs with the flexibility and durability of rubber. This unique combination of features provides advantages in both performance and cost.

The Santoprene™ family of elastomers gives you a material with a broad spectrum of performance characteristics well suited for a variety of end use applications. It is available in general purpose and specialty grades, each with a wide range of hardnesses and consistent physical properties. It also offers excellent performance through a wide temperature range (-81°F to +275°F), is fluid, chemical, and ozone resistant, imparts no taste or odor, and has low long-term compression set. The material is lighter than conventional rubber and is 100% recyclable.

Zatkoff Seals & Packings offers Santoprene™ die cut to shape, or slit to a specific width and thickness in coils. Available with or without adhesive.
