Polyurethane Evolution

SINCE 1969 OMS GROUP HAS CONCENTRATED ITS ACTIVITIES ON EVERY TYPE OF POLYURETHANE APPLICATION TE-

CHNOLOGY WITH A SPECIAL ATTENTION IN RESEARCH AND DEVELOPMENT OF NEW MACHINERY

AND PRODUCTION METHODLOGIES.

TODAY, OMS CONTINUOUS PANEL LINES ARE AMNGST THE BEST KNOWN AND WELL ACCEPTED ON THE

MARKET, THE MODULAR CONSTRUCTION CONCEPT OF OUR PLANTS ALLOWS EACH COSTUMER TO CHOOSE

THE CORRECT EQUIPMENT CONFIGURATION AND LEVEL OF AUTOMATION APPROPRIATE TO HIS PRODUCTION

REQUIREMENTS.

CONTINUOUS LINES ARE AVAILABLE FOR THE PRODUCTION OF PANELS WITH FLEXIBLE OR RIGID FACINGS AND CORE

INSULATION IN PUR/PIR POLYURETHANE FOAM, PHENOLIC FOAM OR ROCKWOOL BONDED WITH TWO

COMPONENT POLYURETHANE ADHESIVE.

ENERGY SAVING COMBINED WITH THE NEED FOR GREAT ATTENTION TO SAFETY WILL CONTINUUE TO EXERCISE

AN IMPORTANT ROLE FOR THE FUTURE OF BUILDING CONSTRUCTION. PANELS IN POLYURETHANE WITH RIGID

OR FLEXIBLE SUBSTRATES HAVE EARNED ENOURMOUS SUCCESS IN THE SECTOR OF THERMAL INSULATION OF BUIL-

DINGS, IN THE FIELD OF INDUSTRIAL REFRIGERATION AND ALSO IN THE TRANSPORT AND PACKAGING

INDUSTRIES.

THE SUCCESS IS DUE TO THE FUNDAMENTAL PROPERTIES OF THIS MATERIAL, TO BE PRECISE:

OPTIMUM THERMAL INSULATION DETERMINED BY THE LOWESST POSSIBLE CONDUCTIVITY

LIGHTNESS

ELEVATED MECHANICAL PROPERTIES

GOOD DIMENSIONAL STYABILITY AT HIGH AND LOW TEMPERATURES

EASE OF USE

OPTIMUM PROCESSIBILITY WITH MOST MATERIALS USED IN

BUILDING CONSTRUCTION

EXCELLENT RESISTANCE TO FIRE

GOOD ENVIRONMENTAL IMPACT

THE FINAL SURFACE QUALITY OF THE PU SANDWICH PANELS DEPENDS MAINLY ON

THE ACCURACY AND THE CONSTRUCTION CHARACTERS OF THE DOUBLE BELT

CONVEYOR.

OMS HAS DEDICATED GREAT ATTENTION TO THIS

PARTICULAR ASPECT.

LATERAL FOAM PRESSURE AND TO GUIDE THE UPPER

AND LOWER FACINGS.

LEFT AND RIGHT MOTORISED CHAIN SYSTEM,

SYNCHRONIZED WITH THE MAIN DOUBLE BELT CONVEYOR

SPEED.

EACH SYSTEM IS ADJUSTABLE IN HEIGHT AND IN WIDTH,

IN ORDER TO OPTIMIZETHE PRODUCTION.

FOR ENERGY SAVING AND AT THE SAME TIME, FOR

A SAFE WORKING ENVIRONMENT, THE DOUBLE

BELT CONVEYOR IS FULLY ENCLOSED WITH A

THERMAL INSULATED TUNNEL ENCLOSURE.

AUTOMATIC UP-DOWN MOVEMENT

SYSTEM FOR THE UPPER CONVEYOR

BELT, WITHOUT USING ANY CALIBRATION

SPACERS AND WITHOUT ANY MANUAL

INTERVENTION ON THE DOUBLE BELT
