Polymerization catalyst is fundamental to the production of polyolefins, including polyethylene and polypropylene. In fact, final polymer product properties are determined via the catalyst system and further optimized by the specific polypropylene process. It is a catalyst for bulk polymerization or vapor phase polymerization, which has a high catalytic activity in bulk polymerization or vapor phase polymerization. When it is used in the presence of a small amount of hydrogen, gives an olefin polymer having excellent melt flowability and stereo regularity.
Polymetron analyzers are designed for ease of installation and use, requiring only power connection and sample hydraulics. It is fitted with a quick-loop valve at the bottom of the analyzer, a constant head vessel and minimum sample flow detection to allow for variations in sample pressure, flow, and distance from the analyzer to the fresh-sample point. The principle of operation is that of ion selective electrode measurement after pH conditioning. Sample pH conditioning is essential for limiting the interference of temperature or other ions. Constant buffering is assured using regulated reagent addition across ambient and sample temperature changes.
Polyphenylene sulfide coatings are resin bonded coating with exceptional chemical resistance. It is virtually unaffected by any solvent to 400°F. it may be used as a stand alone material for excellent corrosion and chemical resistance or as a primer for a topcoat. It also has abrasion and wear resistance. This coating is used extensively in the chemical processing industry.
