PVC internal and external lubricant

PVC lubricants are divided into two categories: internal lubricants and external lubricants.

Internal lubrication has a strong affinity with resin, and its function is to reduce intermolecular forces and improve the dispersion of raw material components.polyethylene wax

The external lubricant has a low affinity for the resin and its function is to reduce the friction between the resin and the metal surface

When the temperature increases, the compatibility with PVC increases, and the small-molecule lubricant is easier to enter between the molecular chains, so it becomes an internal lubricant

When the dosage is large, it can obviously delay the plasticizing speed and play the role of external lubrication.
