  1. P.E.T.Poly Ethane Phtetrathalate Made By :- ShraddhaDebnath (28) RiyaDhingra (27) RishitaYadav (26) ShubhamDahiya (29) SiddhantKaul (30)

  2. Introduction What is P.E.T ? What is P.E.T made of ? The term polyethylene terephthalate is a source of confusion because this substance, PET, does not contain polyethylene. Thus, the alternate form, poly(ethylene terephthalate), is often used in scholarly journals for the sake of accuracy and clarity • Polyethylene (sometimes written poly ethylterephthalateene terephthalate), commonly abbreviated PET, PETE, or the obsolete PETP or PET-P, is a thermoplasticpolymer resin of the polyester family and is used in synthetic fibers; beverage, food and other liquid containers; thermoforming applications; and engineering resins often in combination with glass fiber.

  3. Properties of P.E.T Physical Properties . • Molecular formula : (C10H8O4)n • Molar mass : variable • Density : 1.38 g/cm3 (20 °C) • Amorphous : 1.370 g/cm3 • Single crystal : 1.455 g/cm3 • Melting point : 250 °C, 260 °C[ • Boiling point : 350 °C ( decomp.) • Solubility in water practically insoluble • Thermal conductivity 0.15 to 0.24 W m−1 K−1 • Refractive index (nD)1.57–1.58,1.5750 • Specific heat capacity, C1.0 kJ/(kg·K) Related compounds • Related Monomers Terephthalic acid,Ethyleneglycol SiddhantKaul & RishabhGoel

  4. Advantages & Disadvantages Advantages of P.E.T ? Disadvantages of P.E.T ? Non renewable resource. Environmental pollutant( non-biodegradable ). Produces toxic fumes if burnt. Recycling is very costly. Gets deformed under load. • Light in weight. • Can be easily molded. • Corrosion resistant and chemically inert. • Cheap to produce. • Strong and durable. • Does not expand on heating. • Can be manufactured in any size. ShraddhaDebnath& ShubhamDahiya

  5. Uses of P.E.T Uses . • PET is an excellent barrier material, plastic bottles made from PET are widely used for soft drinks . • PET is also used as substrate in thin film and solar cell. • It is also used for making magnetic tapes, used in audio and video cassette recorders. • P.E.T is also used for making pressure sensitive adhesive tapes.
