Polypropylene (PP) is made from propene/propylene monomer and a linear hydrocarbon resin, having chemical formula (C3H6)n. PP is an inflexible and crystalline thermoplastic used generally in regular products, including packaging trays, battery cases, household products, and so forth. The annual U.S. consumption volume of PP is approximately 37 billion pounds and is second only to polyethylene.

Acrylonitrile Butadiene Styrene (ABS) is considered as an impact-resistant engineering thermoplastic and amorphous polymer. It is made by emulsion or continuous mass strategy and has a chemical formula (C8H8·C4H6·C3H3N)n.
The current U.S. production level for ABS is approximately 1.2 billion pounds per year. The main reason for the widespread use of ABS is its unique combination of properties that can be attributed to the composition of its three main components.
Copolyester is the modified form of polyesters, which are combinations of diols and diacids. For instance, if we introduce diacids, like isophthalic acid, or diols, like cyclohexane dimethanol to the polyester polyethylene terephthalate (PET), the material turns into a copolyester. PETG, PCTA, and PCTG are glycol-modified copolyesters, or otherwise known as “glass” polymers.
