Natural Waxes & Esters
Synthesized by Nature
Natural waxes and esters are an extremely diverse range of materials that can be used to lubricate rigid PVC. Natural waxes are synthesized by many plants and animals. Rheogistics offers fatty acids, fatty acid esters, and natural waxes suitable for use in rigid PVC.

Natural waxes can be obtained from hundreds of sources, all of which can lubricate rigid PVC. Plants secrete waxes onto their surfaces as a way to control evaporation, wettability, and hydration.The most important plant wax is carnauba wax, a hard wax obtained from certain Brazilian palm plants. It has many applications, such as confectionery and other food coatings, car and furniture polish, floss coating, and surfboard wax.
The most commonly known animal wax is beeswax, which is used in many pharmaceutical applications, candles, floor waxes, wax paper, and textiles. Spermaceti wax occurs in large amounts in the head oil of the sperm whale; it is used in ointments, emulsions, candles, soaps, cosmetics and for finishing linens. Lanolin is a wax obtained from wool, consisting of cholesterol esters of higher fatty acids; it is used as a base for emollients in cosmetics and shampoos. There are many, many more sources of natural waxes and esters.
All these materials are very versatile and the chemistry is fascinating. However, the cost performance of natural waxes and esters as primary lubricants in rigid PVC simply cannot compete with the cost performance of paraffin waxes. Natural waxes, esters, and acids are most valuable to the rigid PVC industry as secondary lubricants used to fine-tune the performance of paraffin based lubricant systems.

- Detailed product specifications available upon request
- Stearic acid may be prepared from beef tallow (animal) or palm oil (plant). Beef tallow and palm oil are the basic raw materials for production of metallic stearates and fatty acid esters used in rigid PVC.
