PTFE liner vs UHMWPE liner — what to use after PFAS regulation

Can a PFAS-free UHMWPE liner replace PTFE? Compared on friction, wall, bonding and regulation.

Design2026.09.24

Carriers, wires per band, PPI, wire size — the braid terms a quote needs, and how a 4.9 Fr OD stacks up.

Materials2026.09.23

PET stays on the device, FEP is peeled after reflow — use, ratio, temperature and documents in one table.

Design2026.09.22

Why ±0.03 mm is standard, what ±0.02 mm costs in yield, and how to specify small bore and straightness.

Documents2026.09.21

From TDS and MSDS at quotation to ISO 10993 at submission — what to request, and when.

Materials2026.09.20

Four radiopaque fillers, loading by polymer, and the effect on hardness, tolerance and surface.

Design2026.09.19

Fr 1–24 to mm, working inch sizes, guidewire-compatible bores and shrink-ratio maths in tables.

Materials2026.09.16

PA for flexibility and cost, PI for thin-wall strength and heat — decided by temperature, tensile and price figures.

Design2026.09.15

Cutting speed, tooling, cooling, cleanroom machining and batch traceability — the basics of medical PEEK parts.

Design2026.09.09

Start from the clinical task, then set liner, reinforcement, jacket and tolerances — in that order.

Materials2026.09.02

No plasticisers, BPA-free, ISO 10993 passed, bone-like modulus — why PEEK is a medical material.

Materials2026.08.20

From thin-wall tensile strength to braid and coating compatibility — seven reasons PI keeps winning microcatheter liners.

Shows2026.03.23

One booth with Linstant in COEX Hall D. Most asked: small-bore PEEK tolerance, PI tubing, PET heat shrink and PFAS-free liners.
