Armaflex AC is a Class O flexible, closed cell, CFC-free (ozone depletion potential of zero), elastomeric nitrile rubber pipe insulation. It is black in colour and is manufactured in pre-formed pipe sections and sheets. Armaflex AC has low thermal conductivity and high resistance to water vapour transmission. These properties make Armaflex AC particularly suitable for condensation control on chilled water and refrigeration systems.
When evaluated using standard fire tests the material achieves a Class O rating as defined by the Building Regulations Approved. (Please refer C1 for further details.) These tests indicate that in the critical early stages of a sustained fire the use of Armaflex AC will make only a minimal contribution to the overall heat release and spread of flame.
Being flexible the material is easy to install; it is not fibrous and creates no dust during installation or use
Armaflex AC is particularly suitable for buildings with high occupancy levels where a very high standard of fire performance is required, e.g. hospitals, schools, hotels, supermarkets & offices.|
Armaflex AC may be used for pipes, valves, ducts or vessels since it is flexible and easily fabricated. It is particularly suitable for the thermal insulation of complex shapes.
Armaflex AC is used for condensation control, energy conservation and frost protection, in the temperature range -200°C to + 105°C
When used to insulate flat surfaces where the Armaflex AC insulation is adhered directly on to the surface, the operating temperature should not exceed + 85 °C. Sheet with a self adhesive backing is also available.
When Armaflex AC is used outdoors or exposed to Sun Light / UV radiation, it should be protected using Armafinish FR paint. Where Armafinish FR paint is used the overall fire rating of A
