Application And Scope
It is an important chemical raw material and additive, composed of saturated fatty acids mainly C16 and C18, with the general chemical properties of organic acids.
Widely used in food, rubber, plastics, tyre, cosmetics, plastic cold plasticizer, mold release agent, stabilizer, surfactant, rubber vulcanization accelerator, waterproofing agent, polishing agent, metal soap, metal mineral flotation agent, softening agent, pharmaceuticals and other organic chemicals.
It can also be used as a solvent for oil soluble pigments,a wax pencil smoothing agent,and a wax paper polishing agent.
