Fischer-tropsch wax is produced from coal by the fischer-tropsch synthesis process. Use fischer -tropsch wax in PVC as the external lubricants, low viscosity can improve the products producing speed, and can help pigment and filler to disperse. Especially in the high viscosity system’s extrusion has better effect. It can improve the product’s surface gloss absolutely. When used in concentrated color masterbatch, it can wet pigment effectively and decrease extrusion viscosity. Fischer tropsch wax is not only suitable for PVC application, it can also used in hot melt adhesive, release, pipe, pipe fitting, polishing wax, paint, coating, filler and color masterbatch, rubber, candle, textile. Fischer-tropsch wax is indispensable in PVC, hot melt adhesive, paint and color masterbatch.
