POM Resin for Medical Devices

Polyacetal resin (Polyoxymethylene, abbreviated as POM) possesses properties ideal for medical device applications, including strength, rigidity, impact resistance, low wear, low friction, resilience, and creep resistance. Especially in various mechanical components, smooth and quiet operation can be expected.

POM is primarily a thermoplastic resin composed of the structure (-CH₂O-). 
POM resins come in two varieties: homopolymers consisting only of the structure (-CH₂O-) which excel in strength and rigidity, and copolymers that include some (-CH₂CH₂O-) units, which have superior thermal stability.

In the polyacetal business field, Asahi Kasei is the world's only manufacturer* of both homopolymers (TENAC™) and copolymers (TENAC™ -C) with our own proprietary technology.

TENAC™ is a POM resin for medical devices that has been adopted for lancets, which require good moldability and good puncture performance (spring characteristics), and infusion pump guides, which require high friction and abrasion resistance.

​TENAC™ Q5010 has been added to our lineup as a new POM resin for medical devices.
TENAC™ Medical POM Q5010 is a medium viscosity homopolymer.
