Polybond Resin Bonded Slabs

Polybond’s Resin Bonded Slabs provide the best combination of thermal insulation, fire protection and sound absorption properties conforming to standards IS: 8183:93, ASTM C 612 and BS-3958B-5. RB slab is made of fine fibers spun from selected Minerals melted at high temperature and bonded with a thermosetting resin. The uniform distribution, the fine diameter, fiber lay pattern and flexibility of fiber are the unique features of 'Polybond' Resin Bonded Slabs. The properties are controlled to form slabs of predetermined density and thickness. These are quite versatile, easy to transport and easy to cut, fit and handle.


RB slab can work at both high and low temperatures and provide excellent acoustical absorption, Refinery Insulation, noise reduction & sound insulation. These can be used on both flat and slightly uneven surfaces for thermal and acoustical insulation of ductings, ovens, vessels, tanks, cavity walls, curtain walls, sandwich panels and industrial equipment, insulation of flat surfaces of furnaces, ship decks and boilers. 'Polybond' Resin Bonded Slabs can also be used for fire and personnel protection RB slab is used for building application like wall insulation and sound proofing of partitions and false celling’s, air-conditioning duct insulation and industrials insulation like chimney insulation, furnaces insulation, industrials ovens etc. Polybond RB slabs are used in acoustic insulation work for auditorium, theatres, public place and industrial areas where noise reduction is required. RB slab is used in DG canopy and compression canopy, using RB slabs dampens the sound and provide much clan & silent work place.
