About

About

Octudex is the official Korean distributor of Ningbo Linstant Polymer Materials and a medical polymer tubing brand run by people who know the material. Its parent, Octud Co., Ltd., is the Korean authorised distributor for BASF polysulfone and Joyrun PEEK; the tubing itself is manufactured by Ningbo Linstant Polymer Materials.

Medical polymer tubing

A distributor that knows the material

Material expertise

In a catheter, material decides performance more than geometry does. At the same dimensions, PEEK and PEBAX give different torque transmission and kink resistance.

Octudex is run by Octud Co., Ltd., the Korean authorised distributor for BASF Ultrason® polysulfone and Joyrun PEEK, and a supplier of Avient Colorant Chromatics™ high-temperature colour solutions. The company that has been supplying the resin now supplies the tubing drawn from it.

01

Polymer expertise

Our people came up through global chemical companies. What they know about resin goes straight into reviewing a tube specification.

02

Material selection consulting

Tell us the thermal, chemical and mechanical demands and we narrow it to a grade — from before the dimensions are fixed.

03

Proven global sourcing

A supply chain connected directly to BASF, Joyrun and Avient — resin and tubing through one contact.

04

Alternatives, ahead of time

When regulation forces a material change — PFAS, for instance — we propose the replacement grade and the matching tube specification together.
