Which brands disclose their cure system
In a category with no disclosure requirement at all, what a manufacturer volunteers is the most reliable signal you can get.
Why this page exists. In the US these products are sold as novelty goods, which means no law requires a manufacturer to disclose what their product is made of, or to disclose it accurately. So the question stops being “what does the label say” and becomes “which companies tell you things they did not have to tell you.”
Three disclosures separate a serious manufacturer from a reseller: the polymer, the cure system or grade, and the manufacturing location. Each one is checkable. Each one costs the company something to state, because stating it invites someone to verify it.
The scorecard
| Brand | Polymer | Cure / grade | Origin |
|---|---|---|---|
| Vixen Creations | Stated | Platinum | Sonoma, CA |
| Tantus | Stated | Platinum | USA |
| Fun Factory | Stated | Platinum | Germany |
| Uberrime | Stated | Platinum | USA |
| Bad Dragon | Stated | Platinum | USA |
| njoy | Stated | 316L steel | Stated |
| Blush (Avant line) | Stated | Platinum | Partial |
| Aneros | Stated | Silicone over ABS | Partial |
| Pipedream (Icicles) | Borosilicate | N/A for glass | Not stated |
| Doc Johnson (UR3 line) | Trade name only | Not stated | Partial |
| Marketplace sellers | “Silicone” | Never | Never |
What full disclosure looks like
The brands in the top rows publish a product page you can audit. Vixen states platinum cure and names Sonoma. Tantus states platinum cure and names the USA. Fun Factory states platinum silicone and names Germany, which additionally means production under EU REACH chemical restrictions that carry no novelty carve-out the way US rules do.
None of them are legally obliged to say any of it. They say it because the disclosure is a competitive advantage in a market where almost nobody else can make the same claim honestly.
The practical rule. Named polymer, named cure system or grade, named location. A company that publishes all three is accepting accountability the law does not require. That is why disclosure quality carries 15% of the weight in our scoring rubric — a material that is probably fine but unverifiable is a worse purchase than one that is definitely fine.
What a proprietary name is doing
UR3, Cyberskin, Fanta Flesh, Futurotic and the dozens of similar trade names describe how something feels rather than what it is. They are elastomer blends, which means porous, unsterilizable, and degrading on a timeline measured in months.
The commercial logic is straightforward. A trade name is proprietary, so a competitor cannot sell “UR3” and the buyer cannot comparison-shop the material. Naming the actual polymer would make the product directly comparable to silicone at a similar price, which is a comparison it loses.
Treat any invented material name as TPE until the manufacturer names the underlying polymer. That is not cynicism, it is the base rate.
Where glass and steel sit
Rigid materials have their own version of this. For steel the disclosure that matters is the alloy grade, and 316L is the one to insist on because the added molybdenum makes it far more corrosion resistant than 304. For glass it is borosilicate rather than soda-lime, since soda-lime is the cheap window-glass formulation that fractures under thermal stress.
A seller stating “stainless steel” without a grade, or “glass” without a formulation, is doing the same thing a seller stating “silicone” without a cure system is doing.
How to check a brand yourself
- Open the product page, not the marketplace listing. Marketplace copy is written by resellers who never verified anything.
- Search the page for a cure system, an alloy grade, or a glass formulation. If none appears, check the FAQ and the about page before concluding it is absent.
- Check whether a manufacturing location is named. “Designed in” is not “made in.”
- Sanity-check the price. A soft full-size product under about $30 is not platinum cure regardless of the claim.
Questions
Why does cure system disclosure matter so much?
Platinum cure produces no chemical by-product and stays dimensionally stable for the life of the product. Tin cure releases an alcohol by-product and degrades slowly. Platinum costs more to run, so manufacturers who use it say so. Silence is a reasonable signal of tin cure.
Can I test for cure system at home?
No. Both are genuine silicone and both pass every home identification test, including the burn test. Cure system depends entirely on what the manufacturer publishes, which is exactly why disclosure is scored separately from material.
Does a brand reformulating invalidate this table?
It can. Brands change suppliers and update pages, and a product recommended on reputation rather than current disclosure is a recommendation with an expiry date. We re-check this page periodically and date it at the top.
Is a brand that discloses automatically safe?
Disclosure is a signal about the company, not a guarantee about every unit. It is the strongest signal available in a market with no mandatory labelling, which is different from a certification.
