VITROLIS NRL 46 is a light to medium viscosity lubricant and release agent especially designed for lubrication of neck rings in the glass container forming process.
It is primarily designed for production utilising the NNPB process but may also be used on blow/blow and press/blow operations by applying a slightly lighter film than normal.
The formulation is based on a combination of colloidal graphite, sulphur based compounds and film forming/wetting agents.
Being colloidal in particle size, it enables stable formulations to be produced in low viscosity base fluids. This in turn allows for the application of a lighter and more even lubricant film – thus reducing the build up of carbonaceous material on the neck ring and transfer of these residues onto the neck of the formed container.
