Lightly Bonded Mattress
The uniformity of
fiber distribution, the diameter of fibers, the fiber lay pattern and
bulk density are some special features of Sunrock LRB Mattress. Sunrock
rockwool lightly resin bonded mattresses (LRB) consists of fine fibers
spun from selected rocks melted at high temperature and bonded with a
thermosetting resin. They are Machine laid fiber lay pattern and are
backed to form mattresses of predetermined density and thickness.
Mattresses are then
chopped slit and stitched to specified dimensions. Sunrock LRB has
excellent stability. It has controlled thickness and density resulting
in predictable heat losses.
Applications
Sunrock
LRB mattresses are used for Hot and Cold Insulation to Conserve Energy.
it helps to maintain temperature and prevent condensation in process
Industries. Sunrock also reduces noise levels when applied on such
Machine and Buildings. Sunrock also provides human safety from Hot/Cold
Parts. Sunrocks LRB mattress are mainly used for Boilers, Equipment's.
E.S.P. Ducts. Ovens, Furnaces Tanks, Pipe Lines, Distillation Towers,
Chemical Vessels etc.

Thermal Conductivity
Sunrock
mattresses have extremely low K values for wide range of temperatures.
Typical thermal conductivity values for various densities and mean
temperatures are shown in the graph.
Compression Resistance
Sunrock mattresses
offer high resistance to compression. It has good resilience and regain
their nominal thickness after removal of normal compressive load.
Moisture Resistance
Sunrock
LRB Mattresses are good resistant to water vapour, most common salts
and chemicals. It is moisture resistant and do not absorb mositure form
atmosphere.
Corrosion Resistance
Sunrock mattresses do not cause, initiate or promote any kind of corrosion.
Flexibility
Sunrock
mattresses are very flexible. They will essentially retian thickness
while conforming to any irregular shape. Retention of fibers by the
wire mesh prevents cracking or breaking of mattresses.
Fire Resistance
Incombustible when tested as per IS: 3144 (Melting Point of fibers is above 1000oC (1825oF)..
