Tag Archives: PTFE fasteners for corrosion

Q: I’m using PEEK fasteners in hydrochloric acid but am seeing a slight bit of corrosion or degradation of the fastener. Can you recommend a better polymer for resistance? A: For corrosion in HCL, a better choice may be PTFE screws. PTFE fasteners are virtually inert to most organics, acids … Continue reading
