Microcrystalline wax for enhancing the abrasion resistance of rubber

Microcrystalline wax does indeed serve to improve rubber's abrasion
resistance, with its mechanism of action primarily manifested in the
following aspects:
Formation of a surface protective film: Following rubber vulcanisation,
microcrystalline wax gradually migrates to the surface, forming a dense,
continuous physical protective layer. This film effectively reduces direct
contact between the rubber and external abrasive media, thereby mitigating
wear.
‌Enhancing processing properties: During mixing and moulding, microcrystalline
wax acts as an internal lubricant, improving rubber flow and promoting more
uniform product structure, thereby indirectly enhancing wear resistance.
Synergistic anti-ageing: By shielding against ozone, ultraviolet radiation
and oxygen erosion, it delays rubber ageing and cracking, preserving material
integrity and sustaining long-term wear resistance.
Industry application data indicates microcrystalline wax is extensively
employed in rubber products such as tyre treads, conveyor belts and seals to
enhance wear resistance and durability.
