The PTFE liner is a critical part of catheter construction, yet PTFE resists laminating and bonding to other polymers — raising processing difficulty and narrowing where it can be used. Etching and secondary etching solve that.
Process conditions are set against your tube specification and downstream steps.
Used on PTFE inner layers in braid and coil reinforced tubing, and on catheter liners — any PTFE part that has to bond to another layer. Etching activates the surface so adhesives and other polymers hold.
Primary etch for standard bonding; secondary etch for higher bond strength or demanding reflow liners.
Store dark and sealed; recommended use period is given in the TDS.
Yes. TDS · MSDS come with every specification reply. ISO 10993 biocompatibility data varies by grade and lot, so we confirm it with the factory (Linstant) and reply.
Standard sizes start with small sample lots. MOQ and lead time depend on dimensions, material and secondary processing — send OD · ID · wall · tolerance · length · quantity and we reply within one business day.
Inner diameter, wall thickness, length and operating environment — those four settle the item. We reply with TDS, MSDS and MOQ.
