SASOLWAX 6530SA Features & Benefits

Benefits at a Glance
  • The efficiency of SASOLWAX FT products may allow lower concentrations of the external lubricant to be used, particularly when alternative systems lead to blooming.
  • Our products efficiently controls the fusion of PVC (when correctly formulated with internal lubricants), allowing optimal processing and physical properties to be achieved.
  • Reduces power consumption as observed by drop in amps
  • Reduction of volatiles at vent and die exit versus other wax materials, reducing environmental issues during extrusion
  • Provides good metal release
  • Reduces the formation of “hot spots” that result in thermal degradation of the PVC
  • Reduces die lines and improves surface gloss
  • Allows for reduction of external lubricant loading while improving physical properties, such as impact, flexural and tensile strength.
  • SASOLWAX 6530SA is a qualified hydrocarbon wax yielding similar torque fusion response as fully refined 165F melt paraffin with benefit of reduced die drool (beard), faster heat transfer, slightly stiffer melt and higher output.
  • Good cost to performance benefits.
  • Lower plate out / die-drool than other external lubricants.

Sasol SASOLWAX 6530SA Performance Highlights - 3

  • The high efficiency of synthetic SASOLWAX FT waxes moves output bottlenecks from the extruder to downstream take off and cooling capacity.
  • SW B52 and SW B70 are proven to yield excellent physical and esthetic properties to rigid PVC profiles.
  • Fusion of PVC when using SW B52 or SW B70 is highly temperature dependent.
  • Output of PVC with SW B52 or SW B70 is gained via higher screw speeds as the external efficiency reduces melt pressure and torque in the extruder.
General Guidelines

It is essential that proper processing conditions be used in order to take full advantage of the benefits offered by SASOLWAX products. The level of these products required in any application will need to be determined such that the fusion time of the polymer is matched with the optimized process conditions, e.g., line speed.
Our products maintain regulatory approvals over a wide range of PVC, Polymer, and non-polymer applications. Please contact your local Sasol representative for details.
With technical support by Sasol's experts, higher melting point SASOLWAX FT wax can be used as highly efficient lubricants that are proven to yield output benefits.

Technical Details & Test Data

Lubricants for PVC

The Sasol Chemicals – Performance Solutions offers a range of external lubricants that has been specially developed for use during PVC processing, and includes the unique Fischer-Tropsch (FT) products.

The Sasol Chemicals FT products are synthesized using Sasol’s proprietary FT technology, which reacts carbon monoxide and hydrogen to form unsaturated and unbranched molecules. The linear structure of these synthetic hydrocarbons is responsible for the many desirable properties and performance benefits of SASOLWAX, for example, the low viscosity of these products make them very efficient external lubricants in PVC. Sasol’s R&D team have developed unique performing functionality into the SASOLWAX FT product group. These materials yield desirable properties to modify melt viscosity, melt stiffness, fusion rate, and gelation time. These properties often yield the opportunity to increase the output rate of UPVC.

The function of lubricants in PVC

The “melting” behavior of PVC is different from that of semicrystalline polymers. PVC granules have a particulate structure; each granule is an agglomerate of primary particles (“globules”). Each primary particle has an internal fine structure made up of fibrils (“nodules”). The properties of any article fabricated from PVC depend on the original coarse powder structure being destroyed and replaced with a new connected microstructure. This process is known as fusion. Under- or over-fusion results in poor mechanical properties and so it is important to ensure that fusion takes place at the right time during processing. Internal lubricants, which coat the surfaces of the globules to assist the breakdown of the particulate structure, accelerate the fusion process that may lead to over-fusion and polymer degradation. External lubricants, which act between the polymer and metal surfaces, delay fusion. The use of SASOLWAX FT products can benefit and help PVC processors.
