Stearates are stearic acid salts or esters. Stearates are commonly created during saponification procedures, which include processing fats with strong bases to make soaps. They have both hydrophilic and hydrophobic areas, allowing them to act as surfactants.
Metallic stearates have changed in terms of the number of grades custom-made for specific application requirements during the last few decades.For a specific purpose, a variety of metallic stearates are available. This allows end users of metallic stearates to have more alternatives, allowing them to choose specific grades to fit their needs.
Stearates are widely used in the plastic and rubber processing industries due to their excellent lubricating, gelling, stabilising, and anti-caking properties. They also reduce the required extruder pressure for polyolefin and PVC compounding. Stearates are also utilised as a partitioning and densifying agent in the plastics industry. In plastic applications, acid scavengers such as metallic stearates are used. They increase throughput and make creating smoother,low-friction surfaces easier.
Major corporations are investing in the development of suitable grades for specific purposes. This is especially true in the pharmaceutical and cosmetics industries, which have strict guidelines for the ingredients that must be utilised. The polymer and rubber sector is growing, with more complicated product applications; it's also a key industry that's been pushing the demand for bespoke grades.
Stearates come in a variety of shapes and sizes, such as granules, pastilles and prills, flakes, coarse powder, and fine powder. For specific purposes, several types of metallic stearate are utilised. For applications requiring the use of metallic stearates for their high lubricity as well as releasing agents, fine powders offer higher benefits than other forms.
