In extrusion operations, a solid thermoplastic material is melted, forced through an orifice (die) of the desired cross section, and cooled....

Processing involves the conversion of the solid polymer into a desirable size and shape. There are a number of methods to shape the polymer,...

Viscosity is the resistance to flow. As shown in Table 1.5, polymer melts have viscosities of 100 to 1,000,000 Pa-s, whereas water has a vis...

The term fillers refers to solid additives, which are incorporated into the plastic matrix.7 They are generally inorganic materials and can ...

The design of plastic parts requires the avoidance of failure without overdesign of the part, leading to increased part weight. The type of ...

Polymer properties exhibit time-dependent behavior, meaning that the measured properties are dependent on the test conditions and polymer ty...

The mechanical behavior of polymers is dependent on many factors, including polymer type, molecular weight, and test procedure. Modulus valu...

In its solid form, a polymer can exhibit different morphologies, depending on the structure of the polymer chain as well as the processing c...

Polymers come in many forms, including plastics, rubber, and fibers. Plastics are stiffer than rubber yet have reduced low-temperature prope...

A polymer is prepared by stringing together a low molecular weight species (monomer; e.g., ethylene) into an extremely long chain (polymer; ...

Plastics are an important part of everyday life; products made from plastics range from sophisticated products, such as prosthetic hip and k...
