PEBA RO Compounds

On Demand and Off the shelf Pebax® & Barium Sulfate compounds

Pebax® polyether block amide (PEBA) is a plasticizer-free thermoplastic elastomer that offers remarkable processing ease. The Pebax® product range extends from a hardness of 25 shore D (74 shA) to 72 shore D. This wide range of physical and mechanical properties make Pebax® MED an excellent choice for extrusion of medical grade tubing or film applications.

Barium Sulfate (BaSO4) is a mined earth mineral being the most widely used radiopacifier in the medical device industry because of its ease of processing and economically friendly pricing compared to other radiopacifiers. Its white color makes it easy to custom color and it provides better heat and UV stability than other options. However, the lower density of Barium Sulfate (4.5 g/cm3) requires a higher loading to achieve the radiopacity of other options. Typical loading percent in medical plastics is 20wt% – 40wt%.

In an effort to reduce lead times, Compounding Solutions now offers Pebax® SAO1 Med compounds with 20wt% BaSO4 off the shelf. The Pebax® and BaSO4 used are both ISO/USP biocompatible and are of superior quality in dispersion characteristics. This means the compounds can be used for your most difficult applications requiring very thin wall sections.
