Braid-Reinforced Shaft for Catheter Manufacturing

Are you having difficulties with catheter manufacturing?

Coating thickness inconsistencies make your manufacturing difficult.

Poor blood vessel trackability can occur due to sudden changes in stiffness at welded points of the manually assembled tube.

Manual manufacturing can significantly increase the complexity of the catheter's manufacturing process.

Our innovative process solves the difficulties.

Ultra-thin PTFE liner with tighter tolerances maximizes the deliverability of your catheter.

Excellent blood vessel trackability due to its linear transition from a soft tip to the hard proximal end.

A streamlined process for your catheter manufacturing, which minimizes labor, can be more easily validated and is less susceptible to lot-to-lot variations.

How we make it come true?

Our continuous spooling process ensures exceptional consistency with streamlined production.

Ultra-Thin Wall PTFE Catheter LINER for Manufacturing

Asahi PTFE catheter liner features an ultra-thin wall (8μm).

Our innovative process minimizes labor and makes streamlines your catheter manufacturing.

Are you in trouble with catheter liner?

Do coating thickness inconsistencies make your manufacturing difficult?

Do you need a thinner catheter liner to increase space and ensure a smooth delivery?

Our innovative process realizes ultra-thin wall and maximizes consistency.

The continuous spool-to-spool process realizes a liner with an ultra-thin wall with tight tolerances, both maximizing the ID and minimizing the OD of your catheter. 

A streamlined process for your catheter manufacturing, which minimizes labor, can be more easily validated and is less susceptible to lot-to-lot variations.

How consistent is wall thickness?

The actual measurement data of a PTFE Liner is below.

 - Specification:  Wall thickness = 8μm ± 2μm

 - Actual value:   98.6% within spec range (σ = 1.1μm)

For more detail, please see the white paper.

How we make it come true?

Our automated manufacturing process dips a silver-plated copper-core mandrel through a PTFE emulsion, 

realizing both significant streamlining and reduction of cost through the entire catheter assembly process. 

To control quality, we monitor the outer diameter and check the pinhole over the entire length of the manufacturing.

Product specifications

  - Ultra thin wall:     8μm - 13μm (0.0003” - 0.0005”)

  - Wall tolerance:    ±2μm (±0.00008”)

  - Inside diameter:   0.3mm - 2.8mm (0.01” - 0.11”)

  - Excellent lubricity and chemical resistance.

  - Supplied on spool with silver-plated copper-core mandrel (lengths up to 1500 meter)

Optional Tie layer enhances Adhesion

PTFE liner can be supplied with etched or a thin thermoplastic Tie layer (8μm) to enhance adhesion. 

Option of cut lengths or continuous-spooled lengths is available. 

Please see the datasheet for more detail.
