Dongguan Hanwei Technology Co., Ltd. is a high-tech enterprise integrating R&D, production and sales. Its products are mainly used in petrochemical, rubber and plastics, coatings, papermaking and other fields. The main products are zinc stearate , calcium stearate , magnesium stearate , other fatty acid salts, fatty acid esters, water-based zinc stearate, water-based calcium stearate, wood-plastic lubricants, PE wax, wax emulsion and Various rubber additives, etc.
Zinc stearate is chemically composed of zinc ions (Zn2+) and stearate ions (C18H35O2-). It has a molecular formula of Zn(C18H35O2)2 and a molar mass of approximately 632.3 g/mol. Structurally, it forms a crystalline lattice with the zinc ions surrounded by stearate ions. Understanding its chemical composition and structure provides insights into its properties and applications.
One of the primary applications of zinc stearate is as a lubricant. It acts as a release agent, reducing friction between surfaces and preventing them from sticking together. Zinc stearate is often added to rubber and plastic compounds during processing to enhance flow properties and prevent sticking to molds and equipment. Its lubricating properties make it an essential ingredient in various industrial processes.
In the plastics industry, zinc stearate finds wide use as a lubricant, heat stabilizer, and anti-blocking agent. It improves the processability of plastic materials, reduces extrusion pressure, and prevents surface defects. Additionally, it acts as a heat stabilizer, protecting the plastic from degradation during high-temperature processing. Zinc stearate is particularly beneficial in the production of PVC, polyolefins, and other thermoplastics.
Zinc stearate also plays a significant role in the pharmaceutical industry. It is commonly used as a glidant and lubricant in tablet manufacturing. Zinc stearate facilitates the flow of powdered ingredients, ensuring uniform tablet weight and preventing sticking to the machinery. Moreover, it enhances the dissolution rate of tablets, improving their bioavailability.
<p>Yes, zinc stearate can be used in food packaging materials. It is considered safe for indirect food contact applications and is commonly used as a release agent or anti-caking agent in food packaging processes.</p>
<p>Zinc stearate is generally considered to be environmentally friendly. It is biodegradable and does not persist in the environment. Additionally, its non-toxic nature and low risk of bioaccumulation make it a preferred choice over certain alternative additives in many applications.</p>
<p>Its primary function is to provide specific technical properties rather than serve as a significant source of dietary zinc.</p>
<p>Zinc stearate is considered safe for use in cosmetics and personal care products. It has a long history of use and is generally recognized as safe by regulatory authorities.</p>
