A thermoplastic, or thermosoftening plastic, is any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. [ 1 ] [ 2 ] Most thermoplastics have a high molecular weight .
Thermoplastics currently represent a relatively small part of the PMC industry. They are typically supplied as nonreactive solids (no chemical reaction occurs during processing) and require only heat and pressure to form the finished part. Unlike the thermosets, the thermoplastics can usually be reheated and reformed into another shape, if desired.
Thermoplastic polyurethane (TPU) is any of a class of polyurethane plastics with many properties, including elasticity, transparency, and resistance to oil, grease, and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.
Either thermoplastic or thermosetting polymers may be used. One of the most widely used thermoplastics is a polyamide polymer nylon. [3] The first mouldable composite was Bakelite. This used wood flour fibres in phenolic resin as the thermoset polymer matrix. As the fibres were only short this material had relatively low bulk strength, but ...
MARTINSBURG, W.Va. – In the basement research lab of the agency that regulates America's firearms, two dozen 3D printers hummed, stringing thermoplastic filament into computer-designed patterns ...
There are many synonyms for the term high-performance plastics, such as: high temperature plastics, high-performance polymers, high performance thermoplastics or high-tech plastics. The name high temperature plastics is in use due to their continuous service temperature (CST), which is always higher than 150 °C by definition (although this is ...
The most common type of fibers used in short fiber thermoplastics are glass fiber and carbon fiber [2]. Adding short fibers to thermoplastic resins improves the composite performance for lightweight applications. [1] In addition, short fiber thermoplastic composites are easier and cheaper to produce than continuous fiber reinforced composites. [1]
