ROCKWOOL FIBERTEX 650 / FIBERTEX R100 

INDUSTRIAL BLANKET AND BOARD 

 

Product Description Fibertex-650 is a high density mineral fibre for thermal and acoustical insulation.

 

It consists of long, fine fibres, spun from molten natural rock and formed into resinbonded slab and blanket. A suitable finish such as metal cladding is recommended to protect the insulation from weather or mechanical damage. 

 

Applications 

Fibertex-650 is ideal for the insulation where both high temperature and mechanical vibration conditions are present, e.g. Furnace, Boiler, Hot gas duct, Exhaust flues, Reactor. It is mostly used in Power generating, Metallurgical, Oil refining and Petro-chemecal plants and equipments.

 

Fibertex-650 is easily installed by impaling with pins and securing with speed clips. Detailed fixing recommendations are available from CSR offices. 

 

For small diameter vessels or irregular shaped surfaces, Fibermesh-650 is recommended in use. Furthermore, Fibertex-650 still provides superior sound absorption and used as fire-safe insulation. 

 

Nominal Density 100 kg/m 3 (6. 1/4 lb/ft 3) 

Maximum Service Temperature Recommended operating temperature up to 650 C (1202 F) Capability of handling intermittent temperature up to 1000 C (1832 F) 

 

Fusion Temperature 

Fusion temperature or Melting point of rockwool at 1350 C (2462 F) 

 

Thermal Conductivity 

0.034 W/mK at 20 C mean temperature 

(0.235 BTU in/ft 2h F at 68 F) 

 

Thermal conductivity of Fibertex-650 varies with the mean temperature as shown in graph according to BS 874-1973. 

 

Insulation performance requirements may be specified in many different ways such as Thermal conductivity, Thermal resistance, Process temperature, Allowable surface temperature or Heat loss. 

 

CSR Application Engineers will provide technical services and more details to meet any specification.

 

Factory Applied Facings 

Product is available to order with wide ranges of factory applied facings such as various grades of aluminium foil, glass floth, glass matt, polyester laminate. 

 

Fire Performance

Fibertex-650 achieves four zero Early Fire Hazard Indices when tested in accordance with AS 1530:Part 3-1976 (same as BS 476 : Part 5, 6, 7-1967) for non-combustible material. 

 

Moisture Resistance 

Exposure to an atmosphere of 50 C and 95% relative humidity for 96 hours results 

 

in moisture absorption of less than 0.2% by volume. Should insulation become wet, full thermal efficiency will be restored on drying out. 

 

Water repellent grade according to BS 2792 section 12 is available to order.

 

Corrosion Resistance 

Fibertex-650 is faintly alkaline and is incapable of corroding steel, copper, or aluminium. To maintain this condition, protection must be provided against contamination from external sources. When tested in accordance with BS 3958 : Part 5-1969, results in a range of pH 7.5-8.0. Fibertex-650 contains less than 15 ppm soluble chlorides. For critical applications involving austenitic stainless steel, a low chloride formulation is available to order.
