How to Choose Between Silicone Tubing & TPE Tubing

Factors to Consider in BioPharm & Pharmaceutical Applications

tubingTubing used in critical applications like pharmaceutical and biopharm has particular requirements involving sterilization, performance, extractables and leachables.  How do you know whether silicone or thermoplastic elastomer (TPE) tubing is best for your application? Consider these similarities and differences to help make your decision….

Tubing manufacturing method:

Silicone is a thermoset material. Raw compound is extruded into tubing and heated.  It undergoes a chemical reaction that permanently sets the tubing’s shape.
TPE is a thermoplastic, a material that will change shape if reheated.  This is what makes TPE heat sealable and weldable.

Temperature resistance:

Silicone: AdvantaPure’s unreinforced silicone tubing (APST) handles temperatures from -100°F to 400°F (-73°C and 204°C).
TPE: AdvantaFlex TPE can be used between -88°F and 275°F (-66°C and 135°C).

Hardness:

Silicone: Shore A 50
TPE: Shore A 65

Validations and extractables:

Silicone: Platinum-cured silicone is inherently purer than perocide-cured silicone and offers fewer extractables (substances that can be drawn out of a material).  AdvantaPure’s APST has undergone testing involving USP, ISO, CFR, EP, 3-A and NSF standards.

TPE: AdvantaFlex biopharmaceutical grade TPE has underonce testing involving USP, ISO, CFR, and EP standards.

Connection methods:

Silicone: Attaches to other tubing and equipment by using sterile connectors.

TPE: Attaches with connectors like silicone but is also sterile weldable, thereby saving the expense of sterile connectors

TPE Tubing

TPE Tubing Features:
