Platinum silicone is a purer, more durable grade of food-safe silicone. Platinum silicone made for baby products is food-grade, but not all food-grade silicone is platinum-cured. The difference comes down to how the silicone is made, and it matters most for the products your baby chews, wears, and eats from every day.
If you have ever flipped over a bib or teether and wondered what "food-grade" actually guarantees, you are not alone. Here is the plain-language version, so you can read any label with confidence.
What is food-grade silicone?
Food-grade silicone is silicone that has been deemed safe for contact with food. In the US, that typically means it meets FDA requirements for food-contact materials. It is a genuinely useful baseline: food-grade silicone is BPA-free, flexible, and heat-resistant, which is why it shows up in everything from spatulas to baby bibs.
Here is the part most labels skip: food-grade tells you what the silicone is approved for. It does not tell you how the silicone was made. That is where curing comes in.
What makes platinum silicone different?
Silicone has to be cured, or set, during manufacturing. There are two common methods:
- Peroxide curing is the standard, lower-cost method used for much of the food-grade silicone on the market. It can leave behind trace byproducts and can produce silicone that yellows, blooms, or turns tacky over time.
- Platinum curing uses a platinum catalyst instead. It is a more expensive process that produces a purer, stronger, more stable silicone with no peroxide residues. Platinum silicone keeps its color and flexibility longer, stands up to the dishwasher, and resists that sticky, degraded feel older silicone products can develop.
In short: peroxide-cured silicone meets the bar. Platinum-cured silicone raises it.
Is platinum silicone safer for babies?
Platinum silicone offers meaningful advantages for baby products specifically. Because the curing process is cleaner, there are no peroxide byproducts to worry about. Because the material is more durable, it holds up to daily chewing, tugging, and dishwasher cycles without breaking down. A material that stays intact is a material that stays safe.
Every Babynetic bib is made from 100% platinum-cured silicone and is free of BPA, BPS, PVC, phthalates, and PFAS. We chose platinum curing for the same reason you are reading this article: what touches your baby's skin and food should be held to the highest standard available, not just the minimum one.
What is LFGB, and how does it compare to FDA-grade?
LFGB is the German food-contact standard, widely considered the strictest in the world. FDA requirements set a material-level baseline, with limits on what can be extracted from the silicone itself. LFGB testing goes further: it measures what migrates out of the finished product under real-world conditions, screens for heavy metals and volatile compounds, and even includes sensory testing for odor and taste.
That is why you will see premium baby brands test to LFGB standards even for products sold in the US. Babynetic bibs meet LFGB standards, the strictest European safety standard for food-contact materials.
Quick comparison
| Standard food-grade silicone | Platinum silicone (LFGB) | |
|---|---|---|
| Curing method | Usually peroxide | Platinum catalyst |
| Residual byproducts | Possible trace peroxides | None from curing |
| Durability | Can degrade, whiten, or turn tacky | Holds color, shape, and flexibility |
| Testing standard | FDA material requirements | LFGB migration and sensory testing, the strictest available |
| Typical use | General kitchenware | Premium baby and medical products |
How can you tell what a product is made of?
Look for the words "platinum silicone" or "platinum-cured" on the product page or packaging, and look for LFGB testing. If a product only says "food-grade silicone," there is no way to know how it was cured. Brands that invest in platinum curing say so. A quick test at home: stretch a silicone product and look for white stress marks. High-quality platinum silicone holds its color.
Why doesn't a Babynetic bib taste like soap?
One of our favorite quality reports came from a mom who put her Babynetic bib through the ultimate test: she licked it. Her verdict? No soap taste.
She was checking for something real. Silicone can absorb oils and fragrances from dish detergent at a microscopic level, especially in the heat of a dishwasher. That matters more for a bib than for a spatula. The catch pocket doubles as a second plate, and warm food that lands there is usually coming right back for another bite.
Quality is the difference. Higher-grade platinum-cured silicone is less likely to take on flavors, while the porous fillers in cheaper silicone soak up detergent fragrance and hold onto it. Babynetic bibs are 100% platinum-cured, and LFGB testing includes sensory evaluation for odor and taste. Your baby's snacks should taste like snacks.
One tip for every silicone product in your kitchen: an unscented detergent keeps flavors where they belong.
FAQs
Is food-grade silicone bad for babies?
No. Food-grade silicone is a safe, well-established material. Platinum silicone is simply a purer, more durable version of it, which is why we consider it worth the upgrade for products babies use daily.
Why does some silicone taste like soap after the dishwasher?
Scented detergents leave residue that silicone can absorb at the surface, and porous fillers make it worse. High-quality platinum silicone resists picking up soap taste. If it ever happens to silicone in your kitchen, a soak in warm water with white vinegar or a baking soda scrub brings it back to neutral.
Is platinum silicone dishwasher safe?
Yes. Platinum silicone handles repeated dishwasher cycles without degrading. Babynetic bibs go right on the top rack.
Does platinum silicone contain platinum?
Only a trace amount of platinum is used as a catalyst during curing. It is inert and locked into the material, which is part of why platinum silicone is so stable.
