Thermoformed acryHc sheet is displacing gel coats in some bathtub appHcations spas have converted almost exclusively to formed acryHc sheet reinforced with glass-reinforced polyester laminations due to higher temperatures and higher stmctural requirements. 

The printing ink industry uses P.Y.120 primarily for decorative printing inks on laminated melamine and polyester resin sheets. In terms of lightfastness, 8% gravure prints in 20 and 40 pm cells on such plates correspond to step 8 on the Blue Scale. Plate-out is not observed. P.Y.120 is insoluble in monostyrene and acetone (Sec. 1.8.1.2). 

The list of applications also includes decorative printing inks for melamine based laminated plastic sheets. It should be noted, however, that P.B.15 1 may not be used in decorative printing inks for polyester-based sheets, because the pigment... 

Decorative laminate is defined in ISO 472 but in common usage has come to mean sheet materials consisting of decorative surface papers impregnated with melamine resin and consolidated under heat and pressure with plies of core paper permeated with phenolic resin. In a wider sense the term can be applied to many associated products—including laminates in solid colour laminates with facings such as metal foils, textiles, or wood veneers polyester laminates direct faced boards and composite boards comprising thin laminates bonded to substrates of various kinds.

Multi-layer epoxy laminates demand excellent electrical insulation and the high purity of FR-1524 (TBBA) used in their production. The flame retardant of choice for transparent, UV stable, polyester resin sheet for the building industry is FR-522, a brominated aliphatic diol that guarantees low discoloration of the sheets during long sun and light exposure.

Sheet products made from mineral-filled LC polyesters variants or multilayer copper and LC polyester laminates have been used for thermoforming and electroplating for printed circuit board. 

Typical Use Foams - polyurethane, PVC, phenolic-resin. Polyester, thermosetting plastics. Laminated sheets. Wood products. Ceramics, concrete, masonry. Metals (aluminium, steel, etc.). ... 

Polyester and polypropylene films have been laminated (ca 1991) to base steel sheet to impart protection to the metal. These laminated metals are used to make two-piece drawn cans. 

In other areas, POD has been used to improve the wear resistance of a mbber latex binder by incorporation of 25% of Oksalon fibers. Heat-resistant laminate films, made by coating a polyester film with POD, have been used as electrical insulators and show good resistance to abrasion and are capable of 126% elongation. In some instances, thin sheets of PODs have been used as mold release agents. For this appHcation a resin is placed between the two sheets of POD, which is then pressed in a mold, and the sheets simply peel off from the object and mold after the resin has cured. POD-based membranes exhibit salt rejection properties and hence find potential as reverse osmosis membranes in the purification of seawater. PODs have also been used in the manufacturing of electrophotographic plates as binders between the toner and plate. These improved binders produce sharper images than were possible before. 

Fleece-Back Sheet. A fleece-back sheet is a nonreinforced polymeric membrane that has had a nonwoven mat made of polyester, weighing 101.7—203.4 g/m, laminated to the back of the sheet. The prime use of the fleece-back sheet is in the fully adhered roofing systems. The fleece provides the chemical separator, which eliminates the need for an adhesive that is compatible with the specific membrane or a compatible substrate. 

The conditions to be met in decorative printing are particularly demanding. Decorative papers for gravure and flexographic printing are used to produce laminated plastic sheets. Pigment selection is a matter not only of the type of resin (melamine or polyester), but also a function of the processing method.
