Al-Etihad Top-Line is a range of asbestos-free sealing products comprising compressed fibre and modified PTFE materials designed to cater for the majority of gasket applications.
Top-Sil-ML1
A unique multilayer material designed to utilise the benefits of NBR and HNBR rubbers. NBR is used in the binder system for many compressed fibre grades due to its good chemical and temperature resistance and good binding properties and is used for the main body of Top-Sil-ML1. HNBR offers greatly improved resistance to thermal degradation and is used in the top and bottom layers to protect the main body of the material from thermal degradation. This multilayer structure affords the material improved temperature resistance and is able to main flexibility when used at higher temperatures than the majority of compressed fibre materials.
Top-Sil-ML1 has WRAS approval for use with potable water, is fire-safe to API 607 and also has TA-Luft (Clean Air) approval.
Al-Etihad Top-Graph-2000
Top-Graph-2000 combines the ease of installation, cutting and handling associated with Al-Etihad-sil materials with the improved thermal and chemical resistance offered by graphite based materials.
Al-Etihad Top-Graph-2000 meets the requirements of BS 7531 Grade X and has TA-Luft (Clean Air) approval.
Al-Etihad Top-Chem-2000
Top-Chem-2000 is a heavy-duty modified PTFE material manufactured with the addition of silicon carbide to improve the mechanical properties of the PTFE base material. Top-Chem-2000 has greatly increased compressive strength and resistance to creep and maintains the excellent chemical resistance. The use of PTFE allows use in food, pharmaceutical and chemically aggressive applications.
Top-Chem-2000 is fire-safe according to API 6FA and ISO 10497 and has TA-Luft (Clean Air) approval.
Al-Etihad Top-Chem-2003
Top-Chem-2003 is a modified PTFE designed for use in low gasket load applications. Glass microspheres aid the compressibility and general mechanical strength with detrimental affecting the material’s chemical resistance and has been developed to be used with glass-lined flanges and other circumstances where compressive load is limited. Top-Chem-2003 can be used for food, pharmaceutical,
Top-Chem-2003 has TA-Luft (Clean Air) approval.
Al-Etihad Top-Chem-2005
Top-Chem-2005 is a modified PTFE optimised for use in acidic applications. The addition of glass improves the mechanical properties of PTFE and increases the operational range of PTFE based materials. Top-Chem-2005 is designed for use in acidic environments and cannot be used with strong alkalis.
Top-Chem-2005 has TA-Luft (Clean Air) approval.
Al-Etihad Top-Chem-2006
Top-Chem-2006 is a modified PTFE optimised for use in alkaline applications. The addition of barium sulphate improves the mechanical properties of PTFE and increases the operational range of PTFE based materials. Top-Chem-2006 is designed for use in alkaline environments and cannot be used with strong acids.
Top-Chem-2006 has TA-Luft (Clean Air) approval.
Al-Etihad Soft-Chem
Soft-Chem is a pure, expanded PTFE material designed for use in low bolt load applications. The multidirectional structure of the PTFE matrix improves the compressive strength and improves resistance to creep. Soft-Chem is based on pure PTFE and is suitable for use in food and pharmaceutical duties and can be used in glass-lined, plastic flanges and steel flanges.
