Thermoplastic olefins (TPO) are increasingly used as a roofing material. [8] TPEs are also widely used for catheters where nylon block copolymers offer a range of softness ideal for patients. Thermoplastic silicone and olefin blends are used for extrusion of glass run and dynamic weatherstripping car profiles. Styrene block copolymers are used ...
The EVA copolymer which is based on a medium proportion of VA (approximately 4 to 30%) is referred to as thermoplastic ethylene-vinyl acetate copolymer and is a thermoplastic elastomer material. It is not vulcanized but has some of the properties of a rubber or of plasticized polyvinyl chloride particularly at the higher end of the range. Both ...
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.
Acrylonitrile butadiene styrene (ABS) (chemical formula (C 8 H 8) x · (C 4 H 6) y · (C 3 H 3 N) z) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F). [4] ABS is amorphous and therefore has no true melting point.
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 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]
Acrylonitrile styrene acrylate (ASA), also called acrylic styrene acrylonitrile, is an amorphous thermoplastic developed as an alternative to acrylonitrile butadiene styrene (ABS), that has improved weather resistance. It is an acrylate rubber-modified styrene acrylonitrile copolymer.
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 .
