High Density Polyethylene

High density polyethylene is a polyethylene thermoplastic made from petroleum. It is resistant to many different solvents and has a wide variety of applications. It is used for cell liners in subtitle D sanitary landfills, wherein large sheets of HDPE are either extrusion or wedge welded to form a homogeneous chemical-resistant barrier, with the intention of preventing the pollution of soil and groundwater by the liquid constituents of solid waste. One of the largest uses for HDPE is wood plastic composites and composite wood, with recycled polymers leading the way. It is also widely used in the pyrotechnics trade. HDPE mortars are preferred to steel or PVC tubes because they are more durable and more importantly they are much safer compared to steel or PVC. Milk bottles and other hollow goods manufactured through blow molding are the most important application area for HDPE.

Himol (Polyisobutylene)

Polyisobutylene is composed of long-chain hydrocarbon formed by polymerization of isobutene, It is transparent nonnoxious high-consistency semi-solid polymer free of impurities.It is made of polyisoprene, which is not gas impermeable. Because polyisobutylene will hold air, it is used to make things like the inner liner of tires, and the inner liners of basketballs.

Holmium is a rare earth element. Its oxide was first isolated from rare earth ores in 1878 and the element was named after the city of Stockholm. It is found in the minerals monazite and gadolinite, and is usually commercially extracted from monazite using ion exchange techniques. It has the highest magnetic strength of any element and therefore is used for the polepieces of the strongest static magnets. Because holmium strongly absorbs nuclear fission-bred neutrons, it is used in nuclear control rods. It is also used in yttrium-iron-garnet and yttrium-lanthanum-fluoride solid-state lasers found in microwave equipment. Holmium lasers emit at 2.08 micrometres, and therefore are safe to eyes. They are used in medical, dental, and fiber-optical applications. Holmium is one of the colorants used for cubic zirconia and glass, providing yellow or red coloring.

Holmium powder is dark gray fine particles, which has  unusual magnetic property. It is stable at room temperature and in dry air, however in dry air and high temperature, it is easy to oxidize. It is soluble in inorganic acid. Holmium metal can compound with various nonmetal elements nearly. It exists in gadolinite, monazite and other rare earth ores. Holmium chloride is the raw material. Ho can process into foil, sheet, rod, powder, wire and sputtering target. The ingot is of REM 99.99% by distillation method. Ho powder is of REM 99.9% and particle size -100mesh and -200mesh. There are two production method of holmium ingots, distillation method and reduction method. The distilled holmium piece is dendritic with higher purity than reduced one.
