Description

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.

Expanded Graphite Sheets
Sealrite expanded graphite sheets is made from pure mineral graphite and formed into sheets through a laminar process. Commonly used for gaskets for flanges and connections in demanding application or as an asbestos gasket substitute. Sealrite offers expanded graphite sheets in the following styles:
Style 188: Pure homogeneous expanded mineral graphite
.This style offers the highest temperature rating for inert or reducing environment of up to 2000oC
Style 388: Expanded mineral graphite with steel foil sheet reinforcement
The steel foil insertion allows for better handling and higher operating pressure
Style 488: Expanded mineral graphite with tanged stainless steel 316 reinforcement
Stainless Steel 316 sheet allows the material to achieve substantially higher dynamic loading giving it a high blow out resistance and mechanical strength. The insertion also allows for better handling.
