1. Inhibit material degradation
PVC has a large friction heat generation characteristics of materials, materials in the
processing of local overheating and degradation and lead to degradation of materials as
a whole.
2. Modulating resin plasticizing
In plastic thermoplastic processing, the heat required for resin plasticizing comes from
the conduction from the cylinder wall and the surface of the screw and the friction of
the material during the feeding and compression stages. However, the transfer of heat
through the conduction is slow and can not meet the needs, Friction is the main source
of heat. It is not difficult to understand that PVC lubricants can reduce the interaction
between PVC molecules through internal lubrication and promote plasticization,
or through the role of external lubrication to slow down the heating rate of plastic and
reduce the transfer efficiency of mechanical forces in materials and inhibit plasticizing.
3. Changing the melt flow behavior
The flow behavior of melt can be changed by PVC lubricant through the action of
internal and external lubricant. The internal lubrication reduced the melt viscosity but
did not affect the adhesion to the metal surface. Obviously, the stronger the internal
lubrication, the higher the melt flow rate. The external lubrication reduces the adhesion
of the melt to the metal surface but does not affect its viscosity, so the melt advances at
the same speed.
4. Eliminate melt rupture
Polymer melt fracture is a flow instability phenomenon of elastic polymer melt due to
adhesion and sliding alternation under high shear stress. The basic lubricating effect of
PVC lubricant is to reduce the melt viscosity, elasticity and the adhesion of the melt to
the metal surface of processing equipment.
