Question

how the plastic is produce​

Answer 1

Answer:

Plastics are made from natural materials such as cellulose, coal, natural gas, salt and crude oil through a polymerisation or polycondensation process. ... The production of plastics begins with the distillation of crude oil in an oil refinery.

Answer 2

Answer:

• Plastics are made from natural materials such as cellulose, coal, natural gas, salt and crude oil through a polymerisation or polycondensation process.
• Plastics also contain crude oil
• Crude oil is a complex mixture of thousands of compounds and needs to be processed before it can be used.
• production of plastics begins with the distillation of crude oil in an oil refinery.
• Each polymer has its own properties, structure and size depending on the various types of basic monomers used.
• Two main processes are used to produce plastics - polymerisation and polycondensation - and they both require specific catalysts.

There are many different types of plastics but there are two main polymer families:-

• Thermoplastics (which soften on heating and then harden again on cooling).
• Thermosets (which never soften once they have been moulded).

Examples of Thermoplastics

• Acrylonitrile butadiene styrene (ABS)
• Polyethylene terephthalate (PET)
• Polymethyl methacrylate (PMMA)
• Polypropylene (PP)
• Polystyrene (PS)

Examples of Thermosets

• Epoxide (EP)
• Phenol-formaldehyde (PF)
• Polyurethane (PUR)
• Unsaturated polyester resins (UP)
