Novel TPV elastomers.Novel polymer chemistry Polymer chemistry or macromolecular chemistry is a multidisciplinary science that deals with the chemical synthesis and chemical properties of polymers or macromolecules. in thermoplastic A polymer material that turns to liquid when heated and becomes solid when cooled. There are more than 40 types of thermoplastics, including acrylic, polypropylene, polycarbonate and polyethylene. vulcanizate elastomers is said to provide greater long-term resistance to heat and solvents than conventional TPV TPV Temporary Protection Visa (Australia) TPV Terminal Punto Venta TPV Third-Party Verification TPV Thermophotovoltaic TPV Thermoplastic Vulcanizate (thermoplastic elastomer) TPV Total Payment Volume compounds, higher tensile strength tensile strength Ratio of the maximum load a material can support without fracture when being stretched to the original area of a cross section of the material. When stresses less than the tensile strength are removed, a material completely or partially returns to its and better long-term elastic recovery, according to the company. In comparative tests by the company, the elastic recovery properties of conventional TPVs (measured by compression set) deteriorated by 20 to 50% after long-term exposure at 125[degrees]C, while the Uniprene XL compounds exhibited a change of only 5%. The TPVs also are said to exhibit substantially lower weight gain after over 500 hours of immersion in IRM (1) (Information Resource Management) See Information Systems and information management. (2) (Inherited Rights Mask) In NetWare 3.x and 4. 903 oil at 125[degrees]C. Their tensile strength values were typically 10 to 20% greater, according to the company. Uniprene XL compounds can be extruded or injection molded and are readily colored. Currently available grades span the durometer A hardness range from 45 to 80. Suggested applications include seals, plugs, grommets and mechanical components, automotive tubing and bellows, glazing strips, weather seals and expansion joints, and electrical insulators. They are said to be cost effective. (Teknor Apex) Circle 108 on card |
