LIPREN T is an aqueous, colloidal dispersion of a polymer of 2-chlorobutadiene (1,3). Its vulcanizates have a slight to medium crystallization tendency and undergo little discoloration when exposed to light. LIPREN T is mainly used in the production of dipped goods, internal and external proofing of fire hoses and impregnation, coating and lamination of fabrics. LIPREN T has the advantage that it can be processed both by the conventional coagulant process as well as by the heat sensitizing process.

Lead is a main-group element. It is also counted as one of the heavy metals. It is used in building construction, lead-acid batteries, bullets and shots, weights, as part of solders, pewters, fusible alloys and as a radiation shield. It is also used as electrodes in the process of electrolysis. Lead compounds are used as a coloring element in ceramic glazes, notably in the colors red and yellow. It is frequently used in polyvinyl chloride plastic, which coats electrical cords. Lead, at certain exposure levels, is a poisonous substance to animals. It damages the nervous system and causes brain disorders. Excessive lead also causes blood disorders in mammals. It is restricted under the RoHS directive.

Lithium is a metal that belongs to the alkali metal group of chemical elements. Under standard conditions it is the lightest metal and the least dense solid element. Lithium and its compounds have several industrial applications, including heat-resistant glass and ceramics, high strength-to-weight alloys used in aircraft, lithium batteries and lithium-ion batteries. Lithium niobate is used extensively in telecommunication products such as mobile phones and optical modulators, for such components as resonant crystals. Lithium is also used in the pharmaceutical and fine-chemical industry in the manufacture of organolithium reagents, which are used both as strong bases and as reagents for the formation of carbon-carbon bonds. Organolithium compounds are also used in polymer synthesis as catalysts/initiators in anionic polymerization of unfunctionalized olefins. Lithium compounds continue to be the gold standard for the treatment of bipolar disorder and are helpful for related diagnoses, such as schizoaffective disorder and cyclic major depression.

Lithium Fluoride

Lithium Fluoride is a colorless solid, that transitions to white with decreasing crystal size inorganic compound.Its structure is analogous to that of sodium chloride, but it is much less soluble in water. It is mainly used as a component of molten salts. Lithium Fluoride is prepared from lithium hydroxide and hydrogen fluoride or by dissolving lithium carbonate in excess hydrogen fluoride, evaporating to dryness and heating to red heat.It is also used as a means to record ionizing radiation exposure from gamma rays, beta particles, and neutrons in thermoluminescent dosimeters.Lithium fluoride is widely used in PLED and OLED as a coupling layer to enhance electron injection. It is also used as fluxing agent for the glass , ceramics and enamel industries. It is a raw material for optical lenses and prisms.
