PVC is very popular for tubing due to its wide chemical resistance, excellent pumping life and highly competitive price. However many PVC materials contain Phthalate plasticisers, which are increasingly becoming a concern under REACH regulation.

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.
