Raw Materials & Manufacturing Process
MK-880B is produced using high-molecular-weight organosilicon monomers as the core raw material, through high-temperature oxidative polymerization, graft modification, and melt granulation.
The resulting polymer is water-insoluble and delivers lubrication and mold release performance far superior to conventional PE wax and oxidized PE wax.
Product Description
MK-880B can replace high-end PE waxes, oxidized waxes, and benchmark products such as 316A, OA6, and OA9. It is specifically optimized for high-filled and high-density PVC foaming systems.
Product Functions & Key Advantages
- Higher Processing Speed & Lower Torque:
Significantly improves plasticization rate and extrusion efficiency, reduces equipment load, and extends service life - Outstanding Cost Performance:
Low dosage required; enables higher calcium carbonate loading, greatly reducing raw material cost - Superior Late-Stage Lubrication:
Enhances mold release and surface gloss, improving board flatness and brightness - Excellent Foaming Compatibility:
Improves cell uniformity, ideal for high-density foamed boards and high-calcium formulations
