Lubricants used in plastics processing, or specifically in PVC processing, are functional additives designed to facilitate the flow of the polymer molten material through the production equipment. External lubricants, characterized by their low polarity with the PVC matrix, reduce friction between the molecular chains and the internal walls of the machinery. This, in turn, results in lower flow resistance, less heat generation of the molten material, reduced torque, and less sticking of the material to the equipment. Ultimately, this translates into increased productivity, fewer machine downtimes, and less burnt-out parts.
It is important to understand the polarity mechanism and its effect on plastic melting during the production process when using these ingredients. They are primarily used in rigid PVC applications because they do not negatively affect the thermal distortion temperature (or structure) of the finished products. They can also be used in polyethylene or polypropylene, although their function differs from that in PVC. Finally, they are also used as dispersing agents in inks and emulsions.
Additionally, there are lubrication packages, which already include internal/external lubricants in their composition, but which have been designed or balanced to achieve an optimal melting point, thus saving the manufacturer the formulation process. Furthermore, they offer the advantage of simplifying their addition during the mixing process, since handling the ingredients separately increases the likelihood of errors in the production area. Manufacturers with a closed feeding system often choose this option to streamline their process and enable automation.
It's a external lubricant with a certain polarity used extensively for manufacturing hydraulic pipe, sanitary pipe o rigid PVC profiles. To avoid clouding, it can only be used in very limited quantities in transparent applications. This lubricant is the new generation of paraffin waxes They allow for reduced dosage between 10% and 20% and improve output during extrusion. They promote melting and provide an excellent surface finish. We have grades with NSF and PPI certification.
The main difference between our different grades is their melting point and molecular weight.
This is a refined grade with a very fine particle size.
Do not confuse conventional paraffin used for candle making with wax.
It is an ideal external lubricant for manufacturing PVC pipes or rigid profiles, increasing productivity and improving the product's surface finish. It can significantly impact your lubrication system by altering the torque or rheology of the PVC in your extruder. Excessive addition can produce undesirable results.
It's a partially external lubricant of the amide group that helps the mass flow in Rigid PVC in addition to serving as a antistatic additive in PVC profiles or an antiblock for PVC heat shrink films. It promotes the release of static electricity by migrating to the surface and forming bonds with the surrounding environment, allowing the charge to dissipate. When combined with other lubricants such as calcium stearate, this additive becomes a multifunctional lubricant.
It is a set of PVC lubricants From those previously mentioned, we offer a package that suits your product and process needs. The advantage of using a package is that it simplifies the mixing process for your formulation team and eliminates the need to grapple with the complex issue of lubrication balance.
Lubrication packs are primarily used for the production of PVC hydraulic and sanitary pipes.
