Micronized wax used for demolding

Micronized wax is used for demolding, primarily as an external release agent
in the processing of polymer materials such as plastics, rubber, and
coatings. By forming a lubricating film on the mold surface, it reduces the
adhesion between the material and the mold, thereby ensuring smooth
demolding, improving the surface finish of the finished product, and reducing
the scrap rate.
‌Mechanism of Action of Micronized Wax in Demolding‌
Physical Barrier: Due to their fine particle size, micronized wax can be
evenly distributed across the mold surface, forming a dense barrier layer.
Reduced Interfacial Friction: Their lubricating properties reduce resistance
to melt flow, improving demolding fluidity.
Good Thermal Stability: Synthetic waxes, such as polyethylene wax and
polypropylene wax, have high softening points and are resistant to
decomposition or migration at high temperatures, making them suitable for
engineering plastic processing.
