Rigid PVC and CPVC extrusion
Fischer-Tropsch hard waxes as external lubricants: longer fusion time, lower fusion torque and longer stability time, all measurable on a torque rheometer.
- Congealing
- 80–108 °C
- Drop point
- 88–117 °C
- Polarity
- non-polar
PVC runs close to the temperature at which it degrades. These buy you stability time, lower torque and a cleaner die.

Fischer-Tropsch hard waxes as external lubricants: longer fusion time, lower fusion torque and longer stability time, all measurable on a torque rheometer.
Low- and high-density oxidized PE waxes across a range of acid values, for PVC processing.
PE wax and Fischer-Tropsch paraffin for compounding, cable and general PVC processing.
Heavy-metal-free alternatives to stearates for expandable polystyrene beads: better flow in storage and expansion, cleaner mould release.

EPS lubricants comply with FDA 21 CFR food-contact regulations, including §175.105, §176.170 and §177.1200. Bands span the grades we supply in each family. Figures are a starting point for sampling; the current TDS and CoA govern.
Packed in 15–25 kg bags.
Technical and safety data sheets, a certificate of analysis on every lot, and the declarations your quality team will ask for — sent without you having to chase them. Figures shown on this site are a starting point for sampling; the current TDS and CoA govern.
It manages friction between the melt and hot metal: longer fusion time, lower fusion torque and longer stability time.
FT wax is the non-polar workhorse for rigid PVC; oxidized PE brings polarity. Many formulations use both — send us yours.
Usually a fraction of a percent. Send us your formulation and we will suggest a starting level.
Yes — micronized and pastille grades dosed at 1,000–5,000 ppm, depending on bead size.
A line or two about what you are making is enough to start — we’ll take it from there.
