Coupling agents.Use of titanates and zirconates 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. and elastomer elastomer (ĭlăs`təmər), substance having to some extent the elastic properties of natural rubber. The term is sometimes used technically to distinguish synthetic rubbers and rubberlike plastics from natural rubber. compounds is described in a technical paper available from the company. Titanate ti·tan·ate n. A salt or ester of titanic acid. or zirconate coupling agents form a less than two nanometer monomolecular monomolecular /mono·mo·lec·u·lar/ (-mo-lek´u-ler) pertaining to a single molecule or to a layer one molecule thick. mon·o·mo·lec·u·lar adj. 1. Of or relating to a single molecule. layer on the surface of any organic/inorganic. They chemically bridge non-silane reactive fillers such as CaC[O.sub.3], carbon black and silica, metal oxides, etc., with polymers. For example, an organotitanate nano (1) Billionth (10 to the -9th power). See space/time. (2) Refers to the nanotech industry in general. See nanotechnology. (3) See iPod nano. coating on carbon black acts as a metallocene-like catalyst on a polymer and lowers the Mooney viscosity, which results in increased flow and increased mechanical properties. Coupling agent liquid, powder and pellet forms, dosage, data and applications methodology in compounding and molding are described in the literature. Typically, when just 0.2 phr titanate is added into a thermoplastic polymer, molding cycle times are decreased on average by 20% as process temperatures are reduced 10%. Optimum dosage is determined by the materials used in the compound and desired results. Kenrich Petrochemicals Circle 108 on card |
