ULTRA-LEASE 400 G 5

ULTRA-LEASE 400 G 5 is a water based release system for tire molding operations. To aid demoulding of complicated patterns it provides a certain degree of surface slip, thus preventing tearing of the parts.

Silicone Emulsion LE-45AP

Silicone Emulsion LE-45AP is a non-ionic dimethyl silicone fluid emulsion. It is an extremely stable, water-thinned emulsion widely used as a release agent for rubber and plastic products. In particular, Silicone Emulsion LE-45AP is used in the production of rubber latex gloves.Silicone Emulsion LE-45AP is easy to use as an ingredient for the manufacture of dipped latex products, such as gloves.It also used as releasing agent for Rubber, Plastic, Household, Car Care and Polishing.

dolomite (camg(co3)2), calcined Technical

Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO₃)₂. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite. An alternative name sometimes used for the dolomitic rock type is dolostone.

The mineral dolomite crystallizes in the trigonal-rhombohedral system. It forms white, tan, gray, or pink crystals. Dolomite is a double carbonate, having an alternating structural arrangement of calcium and magnesium ions. It does not rapidly dissolve or effervesce (fizz) in dilute hydrochloric acid as calcite does. Crystal twinning is common.

Solid solution exists between dolomite, the iron-dominant ankerite and the manganese-dominant kutnohorite. Small amounts of iron in the structure give the crystals a yellow to brown tint. Manganese substitutes in the structure also up to about three percent MnO. A high manganese content gives the crystals a rosy pink color. Lead, zinc, and cobalt also substitute in the structure for magnesium. The mineral dolomite is closely related to huntite Mg₃Ca(CO₃)₄.

Because dolomite can be dissolved by slightly acidic water, areas of dolomite are important as aquifers and contribute to karst terrain formation
