Applications. Melamine resins are used for the manufacture of many products, including kitchenware, laminates, overlay materials, particleboards, and floor tiles. Melamine and its salts are also used as fire-retardant additives in paints, plastics, and paper. Melamine foam is a special form of melamine resin.A complex, interlinked polymer that cures to a clear, hard, chemically resistant resin, melamine formaldehyde is employed in plywood and particleboard adhesives, laminated countertops and tabletops, dishwasher-safe tableware, and automotive surface coatings.The principal use of melamine resin is as the main constituent of high-pressure laminates, such as Formica and Arborite, and of laminate flooring. Melamine-resin tile wall panels can also be used as whiteboards. Melamine formaldehyde is used in plastic laminate and overlay materials.

What are some uses for phenol formaldehyde and melamine formaldehyde?
The resultant polymers—known as phenol-formaldehyde resin, urea-formaldehyde resin, and melamine-formaldehyde resin—are widely used as adhesives in plywood and other structural wood products.
Why is formaldehyde used in resin?
The largest application for formaldehyde is the production of urea formaldehyde (UF) resins. These amino resins are made by combining urea and formaldehyde heated with a mild acid catalyst like ammonia. UF resins are high performance, low-cost, thermosetting adhesives with excellent abrasion resistance.
Where is formaldehyde used?
Formaldehyde is a strong-smelling, colorless gas used in making building materials and many household products. It is used in pressed-wood products, such as particleboard, plywood, and fiberboard; glues and adhesives; permanent-press fabrics; paper product coatings; and certain insulation materials.

What is formaldehyde used for in medicine?
Health Care Applications
Formaldehyde has a long history of safe use in the manufacture of vaccines, anti-infective drugs and hard-gel capsules. For example, formaldehyde is used to inactivate viruses so they don’t cause disease, such as the influenza virus in making the influenza vaccine.
What is formaldehyde used for in a science lab?
It is also one of the most-used chemicals in research laboratories, where we encounter it in everything from tissue fixation to benchtop perfusions to instrument sterilization and use it to preserve everything from cell cultures to whole-organ specimens.
What is formaldehyde used for in cosmetics?
Formaldehyde-releasing ingredients (eg. Imidazolidinyl Urea, Diazolidinyl Urea, DMDM Hydantoin) are used as preservatives in cosmetic products. Their function is to prevent microbiological growth and spoilage of cosmetics by releasing small amounts of formaldehyde over time.
Which material is used to make electrical switches?
Before the current plastic switches that we are familiar with today, switches were made of porcelain. Then later, Bakelite, which was an early form of brittle plastic, made from formaldehyde and phenol. More recently and increasingly popular, switches are made of thermosetting plastic.
What plastic is used to make electric switches?
PVC is widely used to insulate electric wiring, while thermosets (which can withstand high temperatures) are used for switches, light fittings and handles.
