Metal soaps are derived from long-chain fatty acids and a metal oxide compound. The fatty acids, in turn, are derived from a triglyceride (natural fats and vegetable oils, i.e. renewable feedstocks). Metal soaps – commonly known as metallic stearates – can be produced using synthesis methods like precipitation and melting processes.
Baerlocher portfolio of metal soaps with diverse properties includes calcium stearate, zinc stearate, and zinc behenate. These products can be employed as acid scavengers, stabilizers, lubricants and release agents, among other applications. Metal soaps can enhance production processes, and, in many cases, they enable manufacturers to develop products with smooth surfaces and low friction.
Applications in diverse industries
In the plastics industry, metal soaps are used in the manufacture of PVC products, and during the processing of numerous plastics, including polyamide, polyethylene, polypropylene, ABS and fiber-reinforced plastics (SMC, BMC).
Metal soaps are also used in many other fields including:
