What is thermoplastic?
Thermoplastic (sometimes written as thermo plastic) is a type of plastic made of polymer resins, which becomes a homogenized liquid when heated and hard when cooled. However, when it freezes, thermoplasty becomes glass and a fracture. These features that lend the material its name are reversible. This means that it can be re -heated, transformed and frozen repeatedly. This quality also causes recyclable thermoplasty. Some types that are commonly produced today are polyurethane, polypropylene, polycarbonate and acrylic. The celluloid, considered the first thermoplastic, appeared in the mid -18th century and ruled in this industry for about 100 years. During its top production it was used as a replacement for ivory. Today it is used to produce guitar selections.
Sometimes thermoplastics are confused with thermoset plastics. Although there, it may sound the same, they actually have very different properties. While thermoplasts can be melted to kaPalin and cooled to solid, thermoster plastics deteriorate chemically when they are subjected to heat. Ironically, thermoset plastics tend to be more durable when they let them cool than a lot of thermoplasty.
Thermoplasty also differs from elastomers, although some are considered both. While many thermoplastics can be stretched to the point, they generally tend to resist and remain in the shape they are stretched to. Elastomers, as the name suggests, bounce back. However, adding a softener to the melt may cause the thermoplastic to be more flexible. In fact, this is usually the case where thermoplasty is used to form or push out plastic.
by the specific action of the softener is to reduce the temperature of the glass transition of the material (TG), what is that it is cold and soft when heated. TG changes with each type of thermoplastic and is dictated by its crystallization structure. Tg universityIf you can also be modified by introducing a thermoplastic into a copolymer such as polystyrene. Until the softener was used, some of the thermoplastic parts were prone to rupture in cold weather.
Thermoplasty has existed for a long time, but today they are a huge part of everyday life. For example, acrylonitril butadien -styrene (ABS) is a type of thermoplasty used to make sports equipment, toys (ie lego® blocks) and various parts of cars. Polycarbonate is used, among other things, for compact discs (CD), drinking bottles, food storage containers and glasses. Polyethylene is probably the most common thermoplastic and is used to make shampoo bottles, plastic bags for food and even vests for verification.
