Microcrystalline wax offers core advantages as a mould lubricant: Firstly, its excellent heat resistance and lubricity enable it to form a stable film during high-temperature injection moulding or die casting, reducing friction between the mould and moulded material, preventing sticking, and enhancing demoulding efficiency. Secondly, its good adhesion and film-forming properties ensure uniform coverage of the mould surface, providing sustained lubrication even within complex geometries and reducing mould wear. Furthermore, its high gel strength and crack resistance help maintain structural integrity during repeated thermal cycles, extending mould service life. In practical applications, microcrystalline wax is commonly employed as a pure product or in compound form: For instance, in rubber or plastic moulds, it may serve directly as a release agent or be blended with paraffin wax to enhance the latter's flexibility; in metal die casting, its lubricating properties reduce surface defects and improve product finish.
