    Our Silicone
    Products Are:

    • Heat proof to: 464°F 240°C
    • Heat resistant to: 550°F 290°C
    • Lab tested to decomposition at: 986°F 530°C
    is a very conservative estimate for the the heat resistance of GIR's silicone. In fact, all of our tools will perform admirably at temperatures higher than that - the food-safe silicone we use is not readily combustible, and does not melt or drip. It may discolor around 550-570°F290-300°C or so, with prolonged exposure.

    Many manufacturers’ claims

    about this aspect of their materials are misleading. There’s no special “secret formula” silicone that is food safe but more heat-safe than the rest of the pack. In fact, silicone cooking tools that cite resistance to temperatures like 600°F or 700°F315°C or 370°C are basing that claim on conditions that really can’t occur outside a lab. Great for marketing, but not so good if you actually want consumers to know the product’s true performance limits… say, in a searing hot wok or pan

    Here's the deal:

    Food-grade silicone products that claim higher heat resistance are simply citing results of lab tests like thermogravimetric analysis (TGA) conducted in inert nitrogen or argon gas. The presence of oxygen (like, in every kitchen on planet Earth) will typically cause partial oxidation above 572°F300°C – so that’s about where degradation (or technically, “weight loss” as a result of depolymerization) will start to occur at a rapid rate.

    To sum it all up:

    we’re confident in saying 464°F240°C truly holds up for prolonged heavy-duty exposure, and we know that science is on our side. Truth is, you could take it much higher if you’re willing to test the limits, with some risk of discoloration if you’re too bold and it hangs around at +550°F287°C for too long.

    Heat Retention

    We use a polymer core to give the spatula strength and heft, which has the added benefit of low heat retention (unlike metal, for example). We’re not saying that it can’t ever get hot – stick it in a pot of boiling sauce for a few minutes and yes, the contact areas will heat up. But it won’t retain that heat for long.

    So if you’re using it on a hot skillet and want to turn around for a minute or two, you can do so with little worry. We simply want to qualify the claim of heat resistance with a request that everyone exercises a bit of common sense when testing the limits.
