THERMOPLASTICS Meaning and
Definition
-
Thermoplastics refer to a group of materials that are comprised of long polymer chains that can be easily melted and reshaped repeatedly when exposed to heat. The prefix 'thermo' in thermoplastics refers to their ability to undergo a reversible physical change upon heating. These materials possess unique properties that distinguish them from other types of plastics.
Thermoplastics exhibit an amorphous or semicrystalline structure, based on the specific composition and processing. This structural arrangement allows for the softening and melting of thermoplastics when heated above their glass transition or melting temperature. Unlike thermosetting plastics, which are irreversibly cured and hardened via chemical reactions, thermoplastics maintain their chemical integrity and can be shaped multiple times without undergoing significant degradation in their properties.
The advantageous characteristics of thermoplastics are primarily attributed to their molecular nature. They possess high molecular weights and different degrees of crystallinity, offering a wide range of mechanical, thermal, and electrical properties. Additionally, thermoplastics often exhibit good resistance to chemicals, impact resistance, and a relatively low melting point compared to other types of plastics.
Due to these desirable attributes, thermoplastics find extensive applications across various industries. They are commonly used in manufacturing plastic products such as packaging materials, pipes, automotive parts, electrical insulation, consumer goods, and even in medical devices. The versatility, ease of processing, and recyclability of thermoplastics make them a highly sought-after material in the modern world.
Common Misspellings for THERMOPLASTICS
Etymology of THERMOPLASTICS
The word "thermoplastics" originated from the combination of two root words: "thermo" and "plastics".
The term "thermo" comes from the Greek word "thermos", meaning "hot" or "heat". It is commonly associated with words related to temperature or heat, such as "thermometer" (an instrument measuring temperature) or "thermosphere" (the uppermost layer of the Earth's atmosphere).
The word "plastics" is derived from the Greek word "plastikos", meaning "capable of being shaped or molded". It is connected to the verb "plassein", which translates to "to mold" or "to form".
By combining "thermo" and "plastics", the word "thermoplastics" was formed to describe a class of plastics that can be softened or reshaped when exposed to heat.
