 Sealing
materials and supplies

Graphite
Material
Pure expanded mineral graphite products provides an excellent
gasket material for high temperature, high pressure applications
or for applications where the gasket width is relatively narrow.
The material is resistant to most organic and inorganic acids and
is suitable to seal a very wide range of media. It is almost completely
impermeable to gases and fluids and is commonly used in very demanding
application where low emission is paramount.The material have no
ageing or embrittlement problems common with elastomeric based materials
and displays long term stability of compressibility and recovery
over a wide temperature range. Graphite however is not suitable
for use with very strong oxidising compounds like highly concentrated
nitric acid or chromic acid. |

PTFE Material
PTFE´s high chemical resistance against a wide spectrum of different mediums makes it an exceptional sealing material for aggressive fluids. Altona stocks pure PTFE gaskets and PTFE materials for a wide range of applications.

Cellulose
Fibre Jointing
This is a very economical sealing material. It has excellent oil and fuel resistance and has a maximum continous service temperature of 120oC. |

Compression
Packing
Sealrite provides a comprehensive range of compression packings
for a wide range of applications. Compression or mechanical packings
may be used for both static and non-static sealing functions depending
on the nature of the materials used and the construct of the packing. |

Rubber Material
Rubber
and other rubber like elastomers possesses mechanical properties
that make them excellent for use in a wide range of general industrial
applications including fluid sealing. Many synthethic elastomers
in particular are engineered to resist a range of chemicals and
reduce the ageing effect common to natural rubber. This makes
these materials suitable for use as gaskets, seals, covers, linings
and mats. Sealrite offers a wide range or rubber materials in
sheet or roll form. They may be used for a wide range of applications
as well as sealing material.
