zinc stearate manufacturing process involves the combination of zinc oxide with stearic acid. The product is a highly specialized type of lubricant which is used in a wide variety of industries including metalworking, pharmaceuticals, plastics and rubbers.
Zinc Stearate is manufactured by combining zinc oxide with stearic acid in a high shear process using tightly controlled pressure and temperature conditions. This results in a very fine, powdery material with exceptional properties and a low melting point of 120 degrees Celsius.
This compound is extremely useful in the production of plastics and rubbers as it provides lubrication, release, heat stabilizer and water repellent capabilities. It can also be used to improve pigment dispersion, as an anti-blocking agent and in powder metallurgy applications.
In addition, this compound is a valuable slip modifier that enhances the flow properties of other ingredients in a formulation. It is also a good scavenger of acid in polyolefins, as well as an effective pigment dispersion aid and a good mold release lubricant.
Other important benefits of this compound include a non-stick texture and the ability to gel and become hard. It can be formulated in a number of different particle sizes, ranging from fine powders to coarse granules.
Besides being an excellent lubricant, this zinc compound can also be used as a sanding additive in wood coatings and as a dusting powder for the rubber industry.
This product is a colorless, odorless, free flowing powder with a slight odour that is soluble in benzene but not in water, alcohol or acids. It has a high surface area to weight ratio and is compatible with both rubber and plastics.
