Raw Materials & Manufacturing Process
MK-102 is produced from refined vegetable fatty acids through hydrogenation saturation, continuous distillation, separation and purification, followed by flaking and pulverization.
The product features high purity, low impurities, and excellent whiteness, making it a classic internal lubricant and activator for PVC.
Lubrication Characteristics
Standard internal lubricant that primarily reduces intermolecular friction in PVC, promotes plasticization, and provides minimal external lubrication effect.
