• Chronoprene® Medical Tubing

Chronoprene® Thermoplastic Elastomer Medical Tubing

Chronoprene® is a unique thermoplastic elastomer tubing product used in the medical device industry due to its combination of high elongation, high flexural modulus, and tensile strength. It is significantly less permeable than silicone, yet is heat-sealable, bondable, and formable. Chronoprene® can be sterilized by radiation or ETO and is abrasion resistant and UV stable.

In-House Chronoprene® Design, Engineering & Production Services

Our expert engineers and Chronoprene® medical tubing design specialists understand the advantages and limitations of working with Chronoprene® in comparison with other thermoplastic elastomer tubing system options. We provide our recommendations according to your performance and other specific requirements. Our team has experience blending and alloying Chronoprene® with other materials to create customized formulations for medical tubing products that have been engineered, tested, and proven to meet all the defined requirements.

Custom Chronoprene® Thermoplastic Elastomer Medical Tubing Advantages

Chronoprene® is available in hardnesses from 5A to 75A. We can extrude Chronoprene® to precise I.D., O.D., and wall dimensions. It is excellent for very low durometer applications, such as catheter outer shafts (for added flexibility) or in occlusion balloons.

With ultimate elongation over 1500%, the Material properties of Chronoprene® elastomeric resins enable novel applications and allow device designers to overcome the limitations of traditional materials. Additional Chronoprene® advantages include:

  • Can expand and hold pressures
  • Advantage over silicon (silicon is thermoset material, Chronoprene is thermoplastic)
  • Clarity- translucent
  • Able to bond to high performing balloon tubing
  • Chronoprene® is softer in durameter (down to 5A)

Vergo® Steerable Access Sheath Catheters with Chronoprene® Thermoplastic Materials

New to the market Vergo® catheters incorporate Chronoprene® thermoplastic elastomer materials into the valve design of the product. Vergo® steerable access sheaths enable OEM structural heart solutions for various applications. Vergo® steerable access sheath advantages include:

  • Hydrophilic coating on OD provides very low friction to aid navigation and PTFE liner for low friction ID
  • Tight bend radius designed for transseptal access to atria with 2-way deflection up to 160 degrees
  • Patented design provides precise tip control and stability
  • Sizes available from 18Fr - 32Fr
  • Multiple standard colors available as well as customized color selection
  • USP Class VI compliant
