Internal Lubricant
Introduction:
Internal lubricants: This type of lubricant has good compatibility with resins, and is often mixed into resins to reduce the melt viscosity of the resin and improve its fluidity. Such as butyl stearate, lead stearate and so on. Stearates are both good lubricants and effective stabilizers.
Application:
Widely used in the manufacture of cosmetics, plastic cold resistant plasticizer, release agent, stabilizer, surfactant, rubber vulcanization accelerator, waterproofing agent, polishing agent, metal soap, metal mineral flotation agent, softener, pharmaceuticals and other organic chemicals.In addition, it can also be used as a solvent for oil-soluble pigment, a slider for crayons, wax paper polish, an emulsifier for stearate glycerin and so on.The product is used as lubricant, defoaming agent and raw material of food additive such as stearate glycerin, sorbitan stearate, sucrose ester etc.Used as auxiliary raw materials and daily chemical products raw materials.Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles and films.PVC heat stabilizer, with good lubricity and good light and heat stabilization.In plastic PVC pipes, stearic acid helps to prevent “coking” during processing. The addition of stearic acid to PVC film processing is an effective heat stabilizer, and it also protects against discoloration of the finished film caused by exposure to sulfide.
Applicable industry:
Rubber industryStearic acid plays an important role in the synthesis and processing of rubber.Stearic acid is a widely used vulcanizing active agent in natural rubber, synthetic rubber and latex. It is also used as a plasticizer and softener.In the process of producing synthetic rubber, it is necessary to add stearic acid as emulsifier. When making foam rubber, stearic acid can be used as foaming agent and stearic acid can also be used as mold release agent for rubber products.Cosmetics industryStearic acid is used in cream and cold cream to emulsify and make it a stable white paste.Stearic acid is also the main ingredient in the manufacture of almond honey and milk.Stearate soap esters are widely used in cosmetics industry.
