1.1 Types of Plastics
1.1.1 Polyamide
Polyamides are made of amide monomers connected together with peptide bonds.
Polyamides can be either aliphatic or aromatic. Polyamide 6 contains around 11.2%
of nitrogen. Lauric acid, Myristic acid, Palmitic acid and Stearic acid are some of
the chemicals that are released on the degradation of polyamide 6.
1.1.2 Polyurethane
Polyurethane (PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. Some of the compounds released during the degradation of
polyurethane are Lauric acid, Myristic acid, Palmitic acid, Diethyl phthalate, Dibutyl
phthalate and Di-isobutyl phthalate.
1.1.3 Urea Formaldehyde
Urea-formaldehyde (UF), also known as urea-methanal, is a non-transparent thermosetting resin or polymer. This polymer is made from a combination of urea and
formaldehyde. Chemicals like Lauric acid, Myristic acid, Palmitic acid, Methyl
palmitate, Stearic acid and Methyl stearate are released when urea formaldehyde
breaks down.
1.1.4 Melamine Formaldehyde
Melamine resin or melamine formaldehyde is a resin with melamine rings terminated with multiple hydroxyl groups which are derived from formaldehyde. This
thermosetting plastic material is made from melamine and formaldehyde. Lauric
acid, Myristic acid, Palmitic acid, Methyl palmitate, Stearic acid, Methyl stearate,
Diethyl phthalate, Dibutyl phthalate, Diethylhexylphthalate and Butylated hydroxytoluene are some of the compounds that are desorbed on the degradation of melamine
formaldehyde.
1.1.5 Acrylonitrile–Butadiene–Styrene
Acrylonitrile-butadiene styrene (ABS) is a common thermoplastic polymer. ABS
is a terpolymer made by polymerizing styrene and acrylonitrile in the presence
of polybutadiene. Compounds like Diethyl phthalate, Dibutyl phthalate, Diisobutyl
