The polyethylene waxes that exist in different models are different due to the difference in the material used in polyethylene wax. Each of these PE wax takes on different prices depending on the quality of the polyethylene wax. Polyethylene wax is used in various industry and sold in various polyethylene wax markets. In this article, you can read useful information about the features and how to buy PE wax for PVC.
PVC is a thermally unstable polymer and in order to process it effectively at elevated temperatures, it needs to be compounded with a stabilizer system and other additives, including lubricants. All lubricants are inherently incompatible with PVC, and their function during processing depends on their degree of
compatibility. Lubricants are often classified as internal or external.
- Internal lubricant
An internal lubricant has a higher degree of compatibility with the PVC resin than an external lubricant, but less than a plasticizer, and acts on the surface between PVC grains during processing, as well as providing metal release at the die tip. This will enhance the surface gloss of the finished PVC product. Internal lubricants are usually incorporated at very low addition levels and tend to increase fusion torque. internal lubricant due to the polar functionalities incorporated during the oxidation step.
- External lubricants
are typically non-polar, low molecular weight hydrocarbons, and therefore incompatible with PVC resin. They reduce interparticle friction between PVC granules, and also between PVC granules and the walls of the processing equipment. This action controls
the heat build-up and prevents rapid discoloration of
heat sensitive PVC.A very common problem in industry is over-lubrication ,and this is typically due to the addition of high levels of
external lubricant. The result is a product with low impact strength and gloss.
Pitaris waxes are very effective and economical lubricants especially suitable for the PVC industry. Their benefits include better flow of the PVC melt, better release/anti-sticking, slip and anti blocking effects and properties to the finished article.
These lubricants are especially useful for processes such as calendaring, extrusion, injection molding, foam applications and flexible PVC. They allow various benefits on the melt, e.g. friction reduction and shear dependent viscosity control leading to an enlargement of the processing windows.
PE Wax for PVC Pipe
In profile extrusion, polyethylene waxes can provide increased output rates, reduced calibration plate-out, controlled fusion maintaining physical properties and enhanced surface quality
- Excellent external lubrication providing enhanced gloss and surface quality; delay fusion
- Best combination of external lubrication and fusion control, providing metal release
- Superior additives for metal release; highly efficient fusion promoter enabling controlled pressure build up in
the extruder; excellent distribution of additives resulting in increased melt homogeneity; reduced gloss
- Excellent external lubrication providing enhanced gloss and surface quality; relatively neutral
to fusion. Reduce chattering in calibration unit and reduce melt pressure
