AVKOSEAL® - Cold Flow Resistant PTFE Sealing Tape

Published 06 March 2015 | By AVKO

It is well known that the standard PTFE, that does not have porous structure and is either moulded or extruded, has some bad mechanical characteristics such as very low tensile strength and low resistance to cold flow. The cold flow, especially when pressure is applied, is a particularly serious problem for standard PTFE seals because they tend to flatten under the stress which in time reduces their sealing efficiency. That is why, despite of its exceptional qualities, PTFE is mainly used in situations where high tensile strength and resistance to cold flow are not required.
