Santoprene ®, Pharmaprene® and Clearaprene® (Autoclavable)

Santoprene® exhibits many similar properties to Silicone tubing but at a more competitive price. Its characteristics include very good chemical resistance to fluids such as alcohols, ozone, aqueous systems and corrosive aqueous systems. Furthermore Santoprene® exhibits good flow consistency for peristaltic pump applications and low friction to abrasive materials. It performs well under vacuum conditions. 

This is tough tubing, showing good anti-ageing properties in harsh weather, sunshine and saline applications. Its operational temperature range is wide and it exhibits excellent environmental stability under changing temperatures.

Santoprene® is a proprietry thermoplastic elastomer developed by ExxonMobil Corporation. It is available in 64 Shore A hardness and offers the most effective tubing for small-bore peristaltic pump use.

It is latex-free, RoHS compliant and the material contains no Substances of Very High Concern (SVHCs) as classified by the REACH environmental regulation.  Tested for toxic metals migration according to EN71-ASTM F963-95; BS5665 Part 3. 

We also offer Santoprene® pump tubing that is equivalent to other pump manufacturers ranges.

Santoprene® is a Registered Trade Mark of Exxon Mobil Corporation

Pharmaprene® is a similar product range to Santoprene® and is also offered by Gradko.

Clearaprene® is Gradko's new thermoplastic elastomer (TPE) with very similar performance characteristics, chemical resistance and temperature tolerance as Santoprene®.  This Autoclavable product has the exceptional additional benefit of being clear and with a very smooth surface finish (similar to that of PVC).  This will reduce chemical and particle pickup and internal spallation caused by aggressive particulate media. 

At this time, Clearaprene® products are available by special order only.
