• Fire Redundant
• Light Weight
• U.V. Stabilities
• Long life

Applications

• Chemical Plants
• Power Plants
• Effluent Treatment Plants
• Offshore Platforms
• Paper Plants
• Refineries

Corrosion resistance of resin System

Two standard composites resin system are available. For most of the application isopthlic Polyester fire retardant [FR-P] is widely used. A vinyl ester composites fire retardant resin system [FR-VE] is used where strong acid [ like hydrochloric acide ] , strong alkalis [ Caustic Soda], organic solvent and halogenated organic conditions exits. Sumip fiberglass cable tray incorporates a synthetic veil on the surface of all structural shapes which causes a resin rich layer which enhances corrosion protection. A abbreviated guide can be provided on request to assist in the selection of the proper resin system for individual application.
