Real-World Noise Measurements – Emission and Immission

Polymers can be classified, in terms of fusibility, into thermoplastics or thermosets (thermosets). Thermoplastic polymers melt on heating and solidify on cooling, in a reversible process. They can also be dissolved in suitable solvents. Examples: PET (from beverage bottles), PS (from disposable cups), LDPE (from plastic bags), PVC (from sewage pipes). Thermosetting polymers, by heating…
