Meaning and Definition
A synthetic resin made by the polycondensation of amines or amides with aldehydes, used especially in moulding powders and adhesives.
Any of a class of thermosetting resins derived from the reaction of an amine (such as urea or melamine) with an aldehyde (especially formaldehyde). These materials are known for their hardness, scratch resistance, and good electrical insulation properties.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or application. The term is used identically in both technical registers.
Connotations
Neutral technical descriptor in both variants. Carries connotations of mid-20th century industrial material development.
Frequency
Equally rare in both variants, confined to specialist literature. 'Amino resin' is a more common synonym in general technical discourse.

Common Mistakes When Using “aminoplast”
- Using 'aminoplast' to refer to any amine-containing polymer (it's specific to thermosets from aldehydes).
- Pronouncing the first syllable as 'am-' (like in 'ham') instead of the schwa sound 'uh-mee-noh-plast'.
- Treating it as an uncountable noun only (it can be countable when referring to types).
FAQ
Frequently Asked Questions
No. Bakelite is a phenolic resin (made from phenol and formaldehyde). Aminoplasts are a separate class made from amines/amides (like urea or melamine) and formaldehyde. Both are thermosetting plastics from the early 20th century.
You might find them as the hard, decorative surface layer on laminated furniture (like melamine), in some durable buttons, ashtrays, electrical sockets, or switch plates, and as a binder in plywood or particle board.
In general industry, broader terms like 'amino resins', or specific names like 'UF resin' (urea-formaldehyde) and 'MF resin' (melamine-formaldehyde) are more frequently used. 'Aminoplast' remains a precise categorical term in polymer science.
Cured aminoplasts are generally inert and stable. However, during production and curing, they can release formaldehyde, a volatile organic compound (VOC). Modern manufacturing and regulations aim to minimize residual formaldehyde in finished products.
A synthetic resin made by the polycondensation of amines or amides with aldehydes, used especially in moulding powders and adhesives.
Aminoplast is usually exclusively technical/scientific (materials science, polymer chemistry, industrial engineering) in register.
Aminoplast: in British English it is pronounced /əˈmiːnəʊplæst/, and in American English it is pronounced /əˈminoʊplæst/. Tap the audio buttons above to hear it.

Memory Aids
Mnemonic
Think: AMINO (like in amino acids, containing nitrogen) + PLAST (like in plastic). It's a plastic made from nitrogen-containing compounds.
Conceptual Metaphor
Aminoplast is to traditional plastics what a ceramic glaze is to paint: a harder, more brittle, and heat-set final layer.
