Both waxes are core PVC processing lubricants, yet their origin, structure and cost-performance differ markedly. This article uses real Heyee Chem grades to help you decide.
| Property | FT Wax | PE Wax |
|---|---|---|
| Molecular-weight distribution | narrow, uniform | relatively broad |
| Purity / color | high, white | good, may yellow slightly |
| Lubrication efficiency | high (low dosage) | moderate |
| Dispersion in masterbatch | excellent, stable tinting | good, cost-effective |
| Blooming risk | low | higher if overdosed |
| Cost | higher | lower |
| Grade | Drop point | Form | Use |
|---|---|---|---|
| HY-W104 | ≥117°C | white powder | premium micronized, HMA, PVC |
| HY-102 | >110°C | white powder | HMA, coatings, PVC |
| HY-115 / 115P / 115M | >110°C | powder/bead | general purpose |
| HY-W80 | ~95°C | bead | dispersion, masterbatch |
| Grade | Softening / Drop point | Form | Use |
|---|---|---|---|
| HY-7100D | mp ≥100°C | granule | masterbatch, ink dispersion |
| HY-40 | softening ≥116°C | white bead | masterbatch, HMA |
| HY-OPE-16 series | oxidized, AV 14–18 | granule | water-based / emulsion |
high-end performance / thermal stability / surface gloss → FT wax HY-W104, HY-102 (premium PVC stabilizer, HMA)
cost-performance / masterbatch / ink dispersion → PE wax HY-40, HY-7100D
water-based / emulsion systems → oxidized series HY-OPE-16, HY-9128
In scenarios demanding thermal stability and surface quality — PVC stabilizers, hot-melt adhesives — FT wax's narrow distribution and high purity reduce blooming and improve gloss and yield, usually making it worth the cost. For purely cost-sensitive mass dispersion (ordinary masterbatch, ink), PE wax can cut cost.
Yes, but residues must be thoroughly cleaned between switches to avoid cross-contamination of different-polarity waxes affecting batch stability. A transition cleaning between batches is recommended and should be recorded.
For cost and dispersion, PE wax (Heyee HY-7100D drop point ≥100°C, HY-40 softening ≥116°C) is a good fit; for higher whiteness, narrower distribution and surface gloss (premium masterbatch, coatings), FT wax HY-W80 / HY-115 series is preferable.
Use oxidized wax for water-based/emulsion systems: oxidized FT wax (HY-9128, HY-104-28, acid value 27–30) or oxidized PE wax (HY-OPE-16 series, acid value 14–18, viscosity 200–300 cP). The polar groups provide emulsification and interfacial compatibility.
