Ceramic Fiber Paper
Thin ceramic fibre paper for gaskets, expansion joints and launder back-up
Overview
What it is and where it works
Thin, flexible ceramic fibre sheet made from alumina-silicate fibres with minimal binder, used where a thin insulating layer or seal is needed: gaskets, expansion joints, parting layers and back-up lining for metal troughs. The binder burns out in service. We supply rolls and pre-cut sheets.

Frequently Asked Questions
Can paper be in direct contact with molten aluminium?
It is mainly used as a gasket and back-up layer; direct metal contact depends on the grade and position. Tell us the application and we confirm suitability.
Why does it smoke at first heat-up?
The organic binder burns out cleanly in service, which is normal on the first heating.
