PU FOAM

INTRODUCTION-

Polyurethane (PU) is a polymer primarily composed of organic units interlinked by urethane links.

There are two types of pu.

(1)Thermosetting PU (Do not melts on heating)

(2)Thermoplastic PU

PU formation takes place by reacting a di or poly isocyanate with a polyol.

APPLICATION-

Polyurethane products have numerous uses. Over 75% of PU global consumption is used for foams.products is in the form of foams, both rigid and flexible types being roughly equal in market size. In both cases, the foam is usually behind other materials.

·         flexible foams are for furniture.

·         rigid foams for walls of most refrigerators and freezers & in thermal insulation panels in the construction sector.

·         PU  are used in garments.

·         Polyurethane are used in lining the cup of brassieres.

·         Polyurethane is also used for moldings which include door framess, window headers, pediments.

Polyurethane formulations cover an extremely wide range of stiffness, hardness, and densities. These materials include:

·         Low-density flexible foam used in upholstery, bedding, automotive and truck seating.

·         Low-density rigid foam used for thermal insulation.

·         Soft solid elastomers used for gel pads.

·         Low density elastomers used in footwear

TYPE OF TESTING-

·         Determination of linear dimensions

·         Determination of density

·         Tension test

·         Indentation load deflection test

·         Shear fatigue test

·         Compression test

·         Humidity ageing test

·         Heat ageing test

·         Test for flammability

·         Compression test

·         FITR test

·         Customized tests

·         Failure analysis
