Magnesium Stearate
Metallic Soap Magnesium Stearate - Mg(C18H35O2)2 -
Magnesium Stearate is a high-performance metallic soap additive specially designed for Polyolefin applications. It is widely used as an effective mould release agent and also functions as a lubricant for halogen-free cable compounds, helping to improve processing efficiency and surface quality.
Magnesium Stearate offers excellent compatibility with a wide range of rubber and plastic materials. It can support smoother processing, reduce sticking during moulding operations and improve release performance in different polymer systems.
Tepe Kimya offers an extensive range of Magnesium Stearates for plastic, rubber, Polyolefin and cable applications. In addition to our standard products, we also provide customised additive solutions developed according to customers' individual processing conditions, formulation requirements and end-use applications.
