Pharmaprene® Santoprene ®


Pharmaprene® is designed as a specific ‘drop-in’ alternative material for Santoprene®. It exhibits many similar visible properties to Santoprene®. Its characteristics include very good chemical resistance to fluids such as alcohols, ozone, aqueous systems and corrosive aqueous systems. Furthermore Pharmaprene® exhibits good flow consistency for peristaltic pump applications. 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. It is ideal for use in peristaltic pump systems as a direct replacement for Santoprene®.

It is free of latex and any substances of animal origin. It is fully RoHS compliant and the material contains no Substances of Very High Concern (SVHCs) as classified by the REACH environmental regulation.

Where using Pharmaprene® the Customer must notify Gradko of any FDA Class I and/or European Union Class I medical devices for each specific product and application.


Santoprene® exhibits many similar properties to Silicone tubing. 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.

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. 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.
