Polyethylene Wax Mn 1000: Properties, Applications & Grade Selection

Everything a formulator needs to know about low-molecular-weight polyethylene wax at Mn ≈ 1000 — what the "precisely fractionated" route changes, where it beats cracked wax, which international grade it corresponds to, and how much to add in each application.

Data note. The indicative values above are taken from the HY-1000 Technical Data Sheet (drop melting point ≥ 110 °C, congealing point ≥ 100 °C, penetration < 3 dmm at 25 °C, melt viscosity > 10 cP at 149 °C; ASTM D3954 / D938 / D1321 / D3236). For reference, Mitsui Chemicals publishes Hi-WAX 100P (Mw 900, high-density type) at density 0.950 g/cm³, crystallinity 90%, melting point 116 °C, softening point 121 °C, penetration 2 and melt viscosity 15 mPa·s at 140 °C. Final specification is always confirmed by COA per lot.

1. What "Mn 1000" actually tells you

Polyethylene waxes span roughly Mn 1000 to 10000, and the number is not cosmetic — it sets the three properties that decide where the wax can be used:

2. Why "precisely fractionated" is the real selling point

Most PE wax on the market is made by thermal cracking of polyethylene, which produces a broad molecular-weight distribution with a tail of very light oligomers. HY-1000 is a precisely fractionated low-molecular-weight polyethylene oligomer: the cut is narrow.

Three practical consequences, in order of commercial value:

  1. Batch-to-batch consistency. A narrow distribution means the melt viscosity and melting point do not drift between lots. For a masterbatch producer running high pigment loading, or a powder coater matching a metallic bond finish, drift shows up as visible colour or gloss variation — and is the single most common reason for rejecting a wax supplier.
  2. Low VOC and low odour. Fractionation removes the light ends. This is the entry ticket to automotive interior (VOC / odour specs such as PV 3351), food-contact packaging and hygiene applications — segments where cracked wax is simply disqualified.
  3. Low branching, high crystallinity. The consequence is high hardness and a high softening point at a given molecular weight. Hardness is what delivers abrasion resistance, scratch resistance, anti-blocking and polish durability.

3. International grade equivalents

Locating a wax in the global grade table is the fastest way to start a technical conversation. The Mn 1000 + high-hardness + low-branching combination occupies a narrow slot:

The 110P and 617 rows are shown as contrast, not as targets: at the same Mn ≈ 1000, a high-density low-branching grade is an order of magnitude harder than a low-density grade. If a formulation calls for hardness, matching the molecular weight alone is not enough.

4. Application guide

Fourteen application areas, ordered by how quickly a supplier can realistically convert them. Dosage figures are typical starting points for formulation work.

ApplicationWhat the wax doesTypical dosageWhy HY-1000 fits
Colour & filler masterbatchPigment / filler dispersant; raises pigment loading, lowers filter pressurePigment: 5–10%
Filler: 2–5%
Low melt viscosity wets pigment agglomerates fast; narrow cut keeps colour strength stable lot to lot
Powder coatingsDegassing agent, anti-scratch, matting, texture, hardness0.5–1.5%High whiteness is decisive for metallic-bonded and light-colour powders
Cable compounds (silane-crosslinkable PE, LSZH)External lubricant; reduces torque, prevents scorch, raises extrusion rate0.5–2%Low viscosity and high softening point lower torque without sacrificing heat resistance
WPC & PVC foam boardLubrication and dispersion in highly filled systems1–2 phrHighest dosage of any PVC segment; fastest formulation validation
Rigid PVC (pipe, profile, fitting)External lubricant; metal release, gloss, output rate0.5–1 phrReplaces imported oxidised PE wax / premium synthetic wax at lower cost
Polishes, car care, candlesHardness, gloss, scuff resistance, burn-time extension1–5%High hardness gives durable gloss; high whiteness suits white/light candles

Hot-melt adhesives (EVA, APAO)Viscosity reduction, open-time control, heat resistance10–30%Softening point 105–115 °C cuts viscosity without collapsing heat resistance — the key advantage over paraffin
PUR hot-melt adhesivesViscosity reduction, open-time adjustment1–3%Moisture-cure system: wax loading must stay low, used only as a rheology modifier
Wood & industrial coatingsAnti-blocking, slip, burnish resistance0.5–2%Suited to solvent-borne and UV; water-borne needs the oxidised grade
Investment casting waxRaises softening point and hardness, reduces shrinkage10–25% of the wax blendHigh crystallinity gives dimensional stability of the pattern
Rubber processingMould release, filler dispersion, anti-ozone protection2–6 phrLow branching means slow migration — durable protection, but blend with a lower-MW component to avoid blooming
Asphalt & waterproofing membraneRaises softening point, anti-rutting; warm-mix additive0.5–3%Improves high-temperature performance; must be balanced against low-temperature ductility

5. Where you should NOT use an unoxidised PE wax

Be deliberate about this. HY-1000 is non-polar and has no acid value, which closes off two whole families of applications:
  1. Water-based systems. An unoxidised PE wax cannot be emulsified. Floor polish, water-borne wood coatings, water-based adhesives and textile emulsions all require an oxidised wax with acid value 15–25. For those, use an oxidised grade (Heyee supplies the HY-OPE-16 series).
  2. Applications needing polar compatibility. Low branching means limited compatibility with polar matrices such as PVC, PA and PC. HY-1000 works as an external lubricant; it is not an internal lubricant. Over-dosing leads to blooming and plate-out.
Stating this upfront costs nothing and prevents a failed trial — a failed trial usually means you never get a second one.

7. Frequently asked questions

What is polyethylene wax used for?

Polyethylene wax (PE wax) is used as a pigment dispersant in colour and filler masterbatch, an external lubricant in rigid PVC and WPC, a degassing and anti-scratch additive in powder coatings, a rub-resistance and slip agent in printing inks and coatings, a viscosity modifier and heat-resistance booster in hot-melt adhesives, a processing aid in cable compounds, and a hardening agent in polishes and candles.

What is the melting point of polyethylene wax with Mn 1000?

For a high-density, low-branching grade the melting point is typically around 110–118 °C with a softening point several degrees higher. Mitsui's Hi-WAX 100P (Mw 900, high-density type) is published at 116 °C melting / 121 °C softening. A low-density grade of the same molecular weight melts about 7 °C lower, so density and branching must be specified alongside molecular weight.

What is the difference between PE wax and oxidised PE wax?

Oxidised PE wax (OPE) is produced by oxidising PE wax to introduce carboxyl and hydroxyl groups, giving an acid value typically of 15–25 mg KOH/g. The polar groups make it compatible with PVC and water-based systems and allow it to be emulsified. Unoxidised PE wax such as HY-1000 has no acid value: it is harder and more heat-resistant, but non-polar, non-emulsifiable and suitable only as an external lubricant. See our detailed comparison in PE Wax vs Oxidised PE Wax.

Can polyethylene wax be emulsified or used in water-based systems?

Not in its unoxidised form. Emulsification requires polar functional groups, which means an oxidised PE wax with an acid value of roughly 15–25. Unoxidised PE wax such as HY-1000 is used in solvent-borne, UV and hot-melt systems; for water-based formulations specify an oxidised grade.

Is PE wax the same as Fischer-Tropsch wax?

No. Fischer-Tropsch wax is built from synthesis gas (CO + H₂) and consists mainly of linear alkanes; PE wax is a low-molecular-weight polyethylene made by polymerisation or obtained as a fractionated oligomer. FT wax typically has a narrower distribution and higher linearity; PE wax offers higher hardness at a given molecular weight and lower cost. Honeywell notes in the A-C 617 data sheet that its LDPE homopolymer "can also be partially substituted for FT wax in adhesive applications", which is why the two compete directly in hot-melt adhesives.

What is a good alternative to Mitsui Hi-WAX 100P?

Heyee HY-1000 is positioned as a drop-in candidate for Hi-WAX 100P / HP10A in the Mn ≈ 1000 high-density slot, with comparable hardness and melt viscosity. See the grade-by-grade comparison and substitution checklist. Always validate with your own DSC, penetration and melt-viscosity testing before switching production.

What molecular weight of PE wax is best for colour masterbatch?

Mn 1000–3000 is the usual working range. Low melt viscosity is what allows the wax to wet pigment agglomerates and penetrate their pores under shear. In practice Mn ≈ 1000 gives the fastest wetting; higher-molecular grades (Mn 4000–8000) are chosen when the wax must also carry very high inorganic pigment loadings of up to 75%.

How much PE wax should be added to rigid PVC?

Typically 0.5–1 phr as an external lubricant for pipe, profile and fittings. Highly filled systems such as WPC and PVC foam board run higher, at 1–2 phr. Because unoxidised PE wax has limited compatibility with PVC, exceeding the recommended level risks plate-out and blooming.

Is polyethylene wax FDA approved for food contact?

Polyethylene wax is covered by FDA 21 CFR 178.3710 for use in food-contact applications, subject to the specific limitations in that regulation, and by EU frameworks for plastics intended for food contact. Compliance depends on the individual grade and its documentation, so request the current food-contact statement and REACH status for the grade you are buying.

What is the difference between high-density and low-density PE wax?

At identical molecular weight the difference is dramatic. Mitsui publishes Hi-WAX 100P (high-density, Mw 900) at density 0.950, crystallinity 90% and penetration 2, versus Hi-WAX 110P (low-density, Mw 1000) at density 0.920, crystallinity 80% and penetration 25. High-density grades are harder, have higher melting and softening points and give better abrasion resistance; low-density grades are softer and more flexible.

Can PE wax replace Fischer-Tropsch wax in hot-melt adhesives?

Partially, and it is common practice. In EVA and APAO hot melts, PE wax reduces viscosity while its 105–115 °C softening point helps retain heat resistance, which paraffin cannot do. Complete replacement is unusual because PE wax is more brittle than FT wax and reduces flexibility, so most formulations use a blend rather than a straight swap.
