Useful:

• Chemical Classes: Other Classes -> Stearates
• Canonical SMILES: CCCCCCCCCCCCCCCCCC(=O)[O-].CCCCCCCCCCCCCCCCCC(=O)[O-].[Zn+2]
• Inhalation Risk: Evaporation at 20 °C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly.
• Chemical Composition: Zinc stearate is a chemical compound of zinc.
• Additive in Plastics and Rubber: Zinc stearate is a significant additive widely used in plastics and rubber. Along with calcium stearate, it plays a crucial role in various applications. The structural evolution and behavior of zinc stearate in polypropylene random copolymer (PPR) were explored during melt processing, providing insights into its dispersed structures and evolution behavior.
• Synergistic Modification in Ethylene-Acrylic Acid Co-polymer (EAA): Zinc stearate, along with Surlyn-Zn2+, was used to synergistically modify ethylene-acrylic acid co-polymer (EAA). The combination significantly improved the mechanical properties, crystallinity, thermal stability, and rheological properties of the self-made ionic interlayer membranes.
• Incorporation in Carboxylated Acrylonitrile-Butadiene Rubber (NBR): Zinc stearate was incorporated in varied amounts into carboxylated acrylonitrile-butadiene rubber (NBR) to introduce smart traits in the composites. It enhanced mechanical properties such as stress-strain, tear strength, and hardness, and also offered shape memory properties due to its melting nature at relatively higher temperatures.
• Fabrication of Superhydrophobic/Superoleophilic Sponge: Zinc stearate was utilized as a coating material to fabricate a superhydrophobic/superoleophilic sponge. The sponge was dip-coated in a zinc stearate suspension, resulting in a surface modification that altered the surface wettability and converted the sponge for rapid oil/water separation.
