Raw Materials & Manufacturing Process
MK-880A is produced from ethylene, propylene monomers, and long-chain lubricating organic ester monomers through high-temperature oxidative polymerization, catalytic crosslinking, melt homogenization, and underwater pelletizing.
The result is a high-molecular-weight composite lubricant with excellent heat resistance and long-lasting lubrication stability.
Product Description
MK-880A offers excellent compatibility with PVC, fillers, and various additives. It is suitable for extrusion, calendering, and injection molding processes for both rigid and flexible PVC products.
Product Functions & Key Advantages
