Fischer-Tropsch Wax

Fischer-Tropsch Wax (FT wax) is a hydrocarbon-based wax derived from the Fischer-Tropsch synthesis process, which involves the conversion of syngas (a mixture of carbon monoxide and hydrogen) into liquid hydrocarbons. FT wax is characterized by its high molecular weight and straight-chain structure, making it a versatile and valuable raw material in various industries. This wax possesses exceptional properties, including a high melting point, low viscosity, and excellent hardness, making it suitable for applications such as coatings, adhesives, candles, and polishes.

Its chemical composition, devoid of impurities commonly found in natural waxes, contributes to its consistent and reliable performance. Additionally, FT wax is often preferred in the formulation of cosmetic and personal care products due to its stability and skin-friendly characteristics. The controlled production process allows for tailoring FT wax to meet specific requirements, further enhancing its utility in an array of industrial applications.
