Name: PTFE etching · secondary etching
Brand: Octudex

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.

Application

Applications

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.
