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. [1] The principal difference between thermoset elastomers and thermoplastic elastomers is the type of cross-linking bond in their structures ...
Polymer engineering is generally an engineering field that designs, analyses, and modifies polymer materials. Polymer engineering covers aspects of the petrochemical industry, polymerization, structure and characterization of polymers, properties of polymers, compounding and processing of polymers and description of major polymers, structure property relations and applications.
Elastomers are usually thermosets (requiring vulcanization) but may also be thermoplastic (see thermoplastic elastomer). The long polymer chains cross-link during curing (i.e., vulcanizing). The molecular structure of elastomers can be imagined as a 'spaghetti and meatball' structure, with the meatballs signifying cross-links.
Polyether block amide or PEBA is a thermoplastic elastomer (TPE). It is known under the tradename of PEBAX® and VESTAMID® E (Evonik Industries).It is a block copolymer obtained by polycondensation of a carboxylic acid polyamide (PA6, PA11, PA12) with an alcohol termination polyether (Polytetramethylene glycol PTMG), PEG).
Thermoplastic elastomer, a class of copolymers with both thermoplastic and elastomeric properties; Transponder equivalent, a method of comparing communication satellite bandwidths; Triphenylethylene, the parent compound of a group of selective estrogen receptor modulators
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.
Thermoplastic olefin, thermoplastic polyolefin (TPO), or olefinic thermoplastic elastomers refer to polymer/filler blends usually consisting of some fraction of a thermoplastic, an elastomer or rubber, and usually a filler. [1]
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.
