DESCRIPTION

TEADIT 24B is a multi-puropose joint sealant manufactured from 100% expanded PTFE fluorocarbon material, supplied as a continuous low density cord with a self-adhesive backing strip. It is soft and resilient, allowing it to conform easily to all surface irregularities and to compress to a thin ribbon under pressure.

The unique characteristics of PTFE contribute to the long life of joints made with TRADIT 24B.

CHEMICAL

RESISTANCE

Because TREDIT 24B is manufactured form 100% PTFE, it is an inert material which can be used in many applications against corrosive media, except molten alkali metals and elemental fluorine.

Resistant to weathering and uv-radiation, non-ageing.
