Synthetic ice panels are made three ways — injection moulding, extrusion, and sinter pressing — and the process determines almost everything that matters. Price follows the process. So does performance.
This guide explains what separates them, what molecular weight actually means, and the questions worth asking any manufacturer before you buy.
1. Injection moulding
Molten polymer is injected into a mould to produce a finished tile with a honeycomb underside.
- One skateable side
- Moulded connections that resist lipping
- Defined, visible seam gaps
- Typically made from lower-cost resin
- Hollow construction, which increases skating resistance because the tile flexes underfoot
Best for: home use, training pads, non-skate applications.
Not suited to: commercial installations, public rinks, or anything with sustained traffic.
Injection-moulded tiles are the entry point to the category. They’re inexpensive and easy to ship, and if you’re buying a shooting pad for a garage they’re entirely reasonable. They aren’t a community rink surface.
2. Extrusion
Polymer pellets are melted and forced through a die to form a continuous sheet, which is then cut and CNC-routered into panels.
- Two skateable sides
- CNC-routered interlocking connections
- Almost imperceptible seam gaps
- Typically HDPE at high molecular weight (HMW)
Glide on extruded panels can feel underwhelming from a standstill — what skaters describe as being stuck in “first gear.” The trade-off is grip: the additional blade traction makes extruded surfaces genuinely good for hockey training, and many players and goalies prefer them for skill work over a faster surface.
3. Sinter pressing
Also called compression moulding. Polymer is compressed under high pressure and heat to an exact density and hardness rather than melted and pushed through a die.
- Two skateable sides
- Tongue-and-groove or CNC-routered connections
- The most consistent and durable surface available
- Very high (VHMW) or ultra-high (UHMW) molecular weight
Best for: backyard rinks, hockey training facilities, commercial rinks, schools, municipalities, public installations, high-traffic use.
Because the polymer is compressed rather than extruded, sinter-pressed panels achieve a density and consistency the other processes can’t match. This is the premium tier, and it’s where every serious commercial manufacturer operates.
Molecular weight: the number that actually matters
Every manufacturer will tell you their panels are “high molecular weight.” The term is close to meaningless without a figure attached, because it spans a range of roughly twenty to one.
| Class | Molecular weight | Process | Tier |
|---|---|---|---|
| HMW — high | ~200,000–300,000 g/mol | Extrusion (HDPE) | Entry / budget. Affordable, grippier |
| VHMW — very high | ~500,000 g/mol | Sinter press | Commercial grade |
| UHMW — ultra high | ~4,000,000–5,000,000 g/mol | Sinter press | Commercial grade. Hardest surface |
The line that matters is between extruded and sinter-pressed, not between VHMW and UHMW.
Both VHMW and UHMW are commercial-grade sinter-pressed surfaces, and every serious rink manufacturer in the world operates in one or the other. The step down from either of them to an extruded HMW panel is where performance, durability and consistency actually fall away — a difference of several times over, and the one that shows up in year four.
Within the commercial tier, the meaningful variables are density and press consistency, panel thickness, whether the glide agent is infused through the polymer or sprayed on the surface, and whether both faces are skateable. A higher molecular weight produces a harder surface, which is a trade-off rather than a straight upgrade — and it’s usually reflected in the price.
Here's the problem
Most manufacturers don’t publish the number. You’ll find “high molecular weight polyethylene,” “a special high density molecular structure,” and “premium polyethylene meeting the highest international standards.” What you won’t find, on most manufacturers’ websites, is a figure.
How the market is structured
We reviewed the published specifications of every synthetic ice manufacturer selling into North America. A few patterns are worth knowing before you request a quote.
The category splits into three tiers. Injection-moulded tiles occupy the entry level and are sold largely to homeowners. Extruded HMW panels make up the broad middle, where most of the “budget commercial” market sits. Sinter-pressed panels — VHMW or UHMW — are the commercial and municipal tier.
Two skateable sides is the dividing line. Injection-moulded tiles have a hollow honeycomb underside and can only be used one way up. Extruded and sinter-pressed panels are solid, so both faces are skateable — which effectively doubles service life and halves cost per year. If a supplier is vague about this, they’re selling single-sided.
Manufacturing location is not the same as company location. A number of brands headquartered in North America manufacture their panels in Europe or Asia. Ask specifically where the polymer is produced and where the panels are pressed or extruded — they’re often different places.
Thickness varies more than buyers expect — from about ¼″ at the entry level to ¾″ at the top of the commercial range. Thicker isn’t automatically better, but very thin panels flex underfoot. Municipal tenders frequently specify a minimum thickness, so check the spec before you shortlist.
We’ve deliberately not named competitors on this page. A comparison written by a manufacturer isn’t worth much to you — you should be able to run the checks yourself. The questions below are how.
What to ask before you buy
On the material
- What is the molecular weight, in g/mol? Ask for the datasheet.
- Sinter pressed, extruded, or injection moulded?
- Where is the polymer manufactured, and where are the panels produced?
- Is the glide agent infused through the polymer or applied to the surface? Surface-applied requires reapplication forever.
- Is virgin resin used, or recycled or mixed material?
On the panels
- One skateable side or two? Can panels be flipped when the first face wears?
- What’s the connection type, and what’s the failure rate in the field?
- Can individual panels be replaced, or does wear in the goal crease mean replacing a zone?
- What thickness tolerance do you hold across a batch? Variance produces an uneven surface.
- Are creases and markings embedded in the material or painted on?
On shavings and blade wear
- How much material does the surface shed under normal use?
- How long can a skater expect between sharpenings? Ask for a number — blade dulling is the most common complaint and the least frequently disclosed.
On the commercial terms
- What’s the warranty, and what does it actually cover?
- What’s the lead time from order to delivery, and what’s the install window?
- Is site preparation included, or is that on you?
- Who handles permitting?
- What happens if a panel fails in year three?
Where we sit
We manufacture sinter-pressed VHMW-PE panels in Germany, dual-sided, in 8 mm, 10 mm, 15 mm and 18–20 mm.
Dual-sided at 10–15 years per face means a 20–30 year effective service life — flip the panels when the first side wears rather than replacing the rink. Against a single-sided panel, the cost per year of service is less than half, before you compare sticker prices.
That puts us in the commercial tier — the same sinter-pressed grade as the premium European rink brands — and we’re not priced at the top of the market. That’s a supply chain decision, not a quality one: we manufacture directly rather than through a distributor network.
Most of this industry won’t tell you their molecular weight. Ask anyone you’re quoting for theirs, in writing.
And we build the skate, not just the surface
Every question above is about the panel, because for thirty years that’s the only variable this industry has had. Denser polymers, better glide agents, tighter seams. It has taken synthetic ice a long way and then stopped — because the remaining gap was never really a panel problem.
A steel blade glides on real ice because pressure and friction melt a microscopic film of water beneath it. The blade isn’t sliding on ice — it’s sliding on water. On a polymer surface that film doesn’t exist, so a steel blade ploughs instead of glides, and the surface grinds down the edge. No panel fixes that. The blade is simply the wrong tool for the surface.
CryoBlades™ is the first blade system engineered for polymer from the ground up rather than adapted from steel, developed alongside our panels as a matched system. It closes most of the distance that panel engineering alone was never going to close.
Materials lead time is 8–12 weeks. Installation takes days, not months.
