Microcrystalline wax used for rubber and tires

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.
