In industrial applications, microcrystalline wax is primarily used for rubber protection, thickening greases, moisture protection in packaging, coatings and inks, and precision casting.
Rubber and Tires: Microcrystalline wax acts as a physical antioxidant in rubber. During processing, it migrates to the surface to form a dense film that blocks ozone and ultraviolet rays, preventing cracking and aging in tires and seals. It also reduces mold release adhesion and improves processing efficiency.
Grease Thickening: Microcrystalline wax has high gel strength, excellent adhesion, and protective properties. It is commonly used as a thickening agent for greases and petroleum jelly used in instruments and seals to prevent the separation and migration of liquid oil components.
