The Sichem product range combines excellent chemical resistance with a wide temperature range from cryogenic to 260° C. It is optimised for applications with irregular sealing surfaces or compromised load capacity. Sichem is the choice when seal integrity is vital to achieve minimum leakage due to its close-cell structure.
Flexigraf is a range of products based on graphite laminate reinforced with stainless steel, among other materials. It is highly resistant to chemicals, temperatures up to 700° C and pressures of 200 bar. Unigraf is a graphite-based material that is very easy to process and cut, offering high chemical resistance, temperatures up to 650° C and pressures of 120 bar.
The Mica family are materials designed to withstand extremely high temperatures. Available as sheets and spiral wounds, they can be used in all critical applications where resistance, durability and reliability are required at temperatures up to 1000° C.
The Flexseals range is manufactured from a mix of organic fibres and rubber binders. Designed for maximum versatility, their use of different filler materials guarantees outstanding performance with a wide range of chemicals, temperatures and operating pressures.
