Thermoplastic vulcanizates were first reported in 1962 by A.M. Gessler and W.H. Haslett. [4] In 1973, W.K. Fisher reported the dynamic vulcanization process through his prior work on polypropylene and EPDM rubber-based TPVs with peroxides as a cross-linking agent. This resulted in the commercialization of "Uniroyal TPR" thermoplastic rubber.
Thermoplastic Vulcanizate (thermoplastic elastomer), a material which both heat-moldable and elastic; Third-party verification, confirmation by a third party of a transaction between two parties; Tactical Protector Vehicle, a version of the Plasan Sand Cat sold by Oshkosh Defense; TPV Technology, a Hong Kong–based electronics company
In contrast with thermoplastic processes (the melt-freeze process that characterize the behaviour of most modern polymers), vulcanization, in common with the curing of other thermosetting polymers, is generally irreversible. Five types of curing systems are in common use: Sulfur systems; Peroxides; Metallic oxides
Thermoplastic elastomers show advantages typical of both rubbery materials and plastic materials. The benefit of using thermoplastic elastomers is the ability to stretch to moderate elongations and return to its near original shape creating a longer life and better physical range than other materials.
A thermoplastic is a type of plastic that melts to a liquid when heated, and freezes to a solid when cooled sufficiently. Subcategories This category has the following 2 subcategories, out of 2 total.
Natural rubber is an elastomer and a thermoplastic. Once the rubber is vulcanized, it is a thermoset . Most rubber in everyday use is vulcanized to a point where it shares properties of both; i.e., if it is heated and cooled, it is degraded but not destroyed.
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.
TPU is one thermoplastic elastomer used in fused filament deposition (FFD) 3D printing. The absence of warping and lack of need for primer makes it an ideal filament for 3D printers when objects need to be flexible and elastic. Since TPU is a thermoplastic, it can be melted by the 3D printer's hotend, printed, then cooled into an elastic solid.
