Polybond Rockwool Lightly Resin Bonded mattress

          Polybond Rockwool LRB mattress is made of fine fibers spun from selected rocks melted at high temperature and bonded with a thermosetting resin. The uniform distribution, the fine diameter and flexibility of fiber are the unique characteristics of 'Polybond' Rockwool Lightly Resin Bonded mattress.
          The properties are controlled to form mattress of predetermined density and thickness. The flexibility of mattress enables it to be application curved surfaces & hence are ideal for industrial boiler insulation, hot air duct insulation, tank insulation.
           It can be faced on one side or both sides to form a firm and flexible multipurpose insulating media. The facings may be Aluminium Foil or Galvanized wire mesh or Stainless Steel wire mesh of different specifications. The mattress provides excellent stability, due to uniform thickness and density, resulting in prevention of heat losses.

Polybood LRB mattress

Applications:

Rockwool LRB mattress are recommended for use in the thermal insulation of large vessels, boilers, machinery, equipment’s, ducts, flanges, valves and plates operation at high temperatures. These mattress are exclusively suited for wrapping curved surfaces or for cutting to fit over irregular shapes. Rockwool LRB mattress are user for both hot and cold insulation to conserve energy, maintain process temperature, provide protection from heat and reduce noise level. Rockwool LRB mattress are used for thermal insulation of large diameter pipe, tanks, boilers, ventilation ducts, Refinery Insulation, ovens, furnace and fire insulation of fire doors.
