Laminates

Laminates can be either high Pressure Laminates (HPL) or Low Pressure Laminates (LPL). HPL are more durable, have greater impact strength. These laminates are used in furniture tops and laminate floors, Wall cladding, Cabinets in wood-based panels.

Adhesives

Melamine adhesive resins are mixed with waste wood or wood chips to produce particle board (PB), medium density fibreboard (MFB), which are used extensively in construction works.

Flame retardant coatings

Melamine resins are used in making highly durable, flame retardant coatings. Melamine based flame retardants are preferred over the halogen based retardants because they are environment friendly and cost effective.

Melamine History

In the 17th century, an Englishman, John Osborne made moldings from the natural polymer, horn. By the 19th century, the molded horn industry was thriving and geared to sell mass produced items to the emerging middle classes.

With his brother Charles, Thomas Hancock worked extensively with this material but is now best known for his discovery (1839) of the vulcanization of rubber whilst Goodyear independently discovered it in America. Theirs was the first deliberate chemical modification of a natural polymer to produce a molding material.

Lepage worked in France with albumen and wood flour to produce his decorative Bois Durci plaques, and many others worked with a wide variety of ingredients including seaweed, peat, paper and leather. Nearly 10% of all British patents issued in 1855 referred to molding materials but the major breakthrough was in the modification of cellulose fibers with nitric acid to give the first semi-synthetic plastics material, cellulose nitrate.

Melamine Product

Melamine resin is manufactured by mixing urea with formaldehyde under heat and pressure. The substances begin to polymerize and are forced into a mold which will create the desired shape. Under pressure, melamine releases water, which could make the plastic unstable if it is not removed. The materials finish polymerizing and create a finished product, melamine resin.

Melamine resin is known as a thermoset plastic, because the plastic is fixed after molding. If exposed to enough heat, melamine will melt. For this reason, melamine dishware should not be exposed to high temperatures like those in the oven and microwave. However, the plastic is able to withstand higher temperatures than other plastics. Because it is a thermoset plastic, melamine resin is difficult to recycle.

Melamine can be made into a foam product. Melamine foam has a distinctive structure composed of stacked bubble shapes, which are extremely hard and therefore can easily clean a wide variety of substances. Melamine foam is marketed under a variety of commercial names including Magic Eraser, a cleaning tool well known for removing scuffs and dirt from a wide range of surfaces.

DESCRIPTION OF MELAMINE

Melamine is an organic compound that is often combined with formaldehyde to produce melamine resin, a synthetic polymer which is fire resistant and heat tolerant. Melamine resin is a very versatile material with a highly stable structure. Uses for melamine include whiteboards, floor tiles, kitchenware, fire retardant fabrics, and commercial filters. Melamine can be easily molded while warm, but will set into a fixed form. This property makes it ideally suited to certain industrial applications.
