  2. Thermoplastic - Wikipedia

    en.wikipedia.org/wiki/Thermoplastic

    Polypropylene (PP) is useful for such diverse products as reusable plastic food containers, microwave- and dishwasher-safe plastic containers, diaper lining, sanitary pad lining and casing, ropes, carpets, plastic moldings, piping systems, car batteries, insulation for electrical cables and filters for gases and liquids.

  3. Polyester - Wikipedia

    en.wikipedia.org/wiki/Polyester

    When melting points of the monomers are sufficiently low, a polyester can be formed via direct esterification while removing the reaction water via vacuum. Direct bulk polyesterification at high temperatures (150 – 290 °C) is well-suited and used on the industrial scale for the production of aliphatic, unsaturated, and aromatic–aliphatic ...

  4. Coolmax - Wikipedia

    en.wikipedia.org/wiki/Coolmax

    Like other polyester fabrics, Coolmax is flammable and has a relatively low melting point (~255 °C), giving clothes made from it a tendency to melt and fuse to the wearer's skin when exposed to high heat.

  5. Crystallization of polymers - Wikipedia

    en.wikipedia.org/wiki/Crystallization_of_polymers

    Additional energy is released upon melting a semicrystalline polymer. This energy can be measured with differential scanning calorimetry and compared with that released upon melting of the standard sample of the same material with known crystallization degree. [6] [20] X-ray diffraction

  6. Polycyclohexylenedimethylene terephthalate - Wikipedia

    en.wikipedia.org/wiki/Polycyclohexylenedim...

    Polycyclohexylenedimethylene terephthalate (PCT) is a thermoplastic polyester formed from the polycondensation of terephthalic acid and cyclohexanedimethanol. [1] Its chemical structure is similar to that of polyethylene terephthalate (PET), with which it shares properties like dimensional stability and chemical resistance.

  7. Polycaprolactone - Wikipedia

    en.wikipedia.org/wiki/Polycaprolactone

    Polycaprolactone (PCL) is a synthetic, semi-crystalline, biodegradable polyester with a melting point of about 60 °C and a glass transition temperature of about −60 °C. [ 2 ] [ 3 ] The most common use of polycaprolactone is in the production of speciality polyurethanes .

  8. Metallised film - Wikipedia

    en.wikipedia.org/wiki/Metallised_film

    Metallised films are used as a susceptor for cooking in microwave ovens. [5] An example is a microwave popcorn bag. Many food items are also packaged using metallised films for appearance only, as these produce a package with greater sparkle when compared to competing products that use printed paper or polymer films.

  9. Melting point - Wikipedia

    en.wikipedia.org/wiki/Melting_point

    The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
