How safe is using food-grade silicone in baking and high temperatures?

Silicone baking molds are microwave-safe, freezer-safe, and oven-safe. In 1979, the FDA deemed silicone safe to be used for cooking and everyday usage. Temperature changes will not cause food-grade silicone to leach into foods, a common consumer concern.

What is Food-Grade Silicone?

The food-grade silicone means meets FDA and EU(LFGB)requirements for food contact and safety.  FDA & LFGB-approved silicone is considered food safe, and silicone that has passed LFGB testing is higher quality silicone. Silicone is made from alternating silica and oxygen molecules.

The silicone that makes up ZSR silicone products is made from these foundational elements and combined with carbon to create a raw silicone product. This material is then cured under heat and pressure to create silicone parts that are sturdy, inert and versatile.

Properties of Food-Grade Silicone

Food-grade silicone is a type of silicone that is safe for use with foods. non-toxic type of silicone that doesn’t contain any chemical fillers or by-products, making it safe for use with food. Silicon, the naturally occurring chemical element that makes up silicone, is a metalloid, which means it has properties of both metals and non-metals and is the second most abundant element in the earth’s crust, after oxygen.

Silicone is used frequently in making molds used for food that begin as liquids and solidify. It is non-toxic; does not stain food, dishes, or cookware; is easily removed from cast objects; and is safe for use on various plastic objects.

  • Temperature resistance: Highly resistant to degradation from extreme temperatures and can withstand heating and freezing without leaching off hazardous chemicals. The conventional temperature range of -40 ~ 230 degrees within the long-term use.
  • Easy to clean: Silicone products produced from silicone can be cleaned by rinsing with water after use, and can also be cleaned in the dishwasher. Easy to clean with its smooth and soft surface.
  • BPA-free, therefore, is safe for food.
  • Stable, Durable, and Flexible.
  • Hypoallergenic, odor and stain-resistant.
  • Does not break, peel, or rot, making it the perfect material for eco-friendly products.
  • Lightweight, easy and space-saving, therefore, can be taken everywhere.
  • Different beautiful colors can be blended according to customer needs.
  • More durable than plastic and better for the environment.

Food Silicone in High-Temperature Cooking

Food-grade silicone’s high-temperature resistance is generally 250 degrees, and its short-term high-temperature resistance can reach about 350 degrees. Normally, if you cook Food Silicone products with the food less than 230 degrees. It is safe and can be worked.


Not all of them. Only with the temperature less 250 degrees. It is strictly prohibited to use gas, open flames, or electricity, or use it directly above the heating plate or below the barbecue.

No, High-Temperature changes will not cause food-grade silicone to leach chemicals into foods.

The silicone products is lightweight, non-reactive, shatterproof, and non-stick. Does not break, peel or rot. Stable, Durable and Flexible. Easy to clean.

No, The silicone kitchenware will not degrade overtime with the high- temperature use.

Silicone products can only be used in ovens, airfry, and microwave ovens. When you use silicone molds to do the bakeware with 8 cavities. If you only need 4 cavities cake. Please put water in other 4 cavities. Do not bake the silicone products empty.

Silicone bakeware cools down much faster.

No, The colored and non-colored silicone bakeware is the same safety. The key to safety depends on the material choice. Choice the silicone products made from food-grade silicone.


Check if the products have FDA(Food and Drug Administration) certification in the products and package.

Any products have it’s lifecycle. With around 3-5 years use, we suggest you change to new silicone bakeware.

Tips for safely using silicone in baking and cooking

  • Choice the silicone products with the FDA certification products to use.
  • After each use of the silicone products for cooking, you should clean it with warm water or put it in the dishwasher. And put them in the air to dry. Make sure that the silicone products are used and stored after each use. It’s all dry before.
  • When baking, you can lightly spray a small amount of anti-stick baking pan oil on the silicone surface of the products before baking. The silicone mats or molds should be placed flat on the baking sheet separately.
  • Silicone products can only be used in ovens, airfry, and microwave ovens. It is strictly prohibited to use gas, open flames, or electricity, or use it directly above the heating plate or below the barbecue.
  • Please do not use knives or other sharp objects on silicone products, and avoid heavy pressure and pulling.
  • Due to static electricity, silicone molds are prone to dust. If not used for a long time, they should be placed in a carton away from direct sunlight.

Recommendations on choosing high-quality silicone products

  • Choice the brands that are famous and have passed the FDA.
  • Smell it. The Food Grade Silicone also has a little odor, which is because the production process does not affect the quality, safety, and other issues, and the odor will be automatically eliminated after a period of time
  • Touching: Food-grade silicone has very good toughness and elasticity.
  • Pinch Or Twist Test: The FDA products and ordinary silicone products will change colors. The LFGB standard products will not change color
  • Burn. The high-quality silicone products will have no odor when burned.


In conclusion, silicone products are notable for their wide temperature range tolerance (-40 to 230 degrees Celsius), making them suitable for diverse applications. They are valued for their softness, comfort, environmental friendliness, non-toxicity, and degradability. Additionally, high-quality silicone products are free from harmful substances like lead, BPA, and PVC.

From the above information, we can answer that: Is food-grade silicone in high temperatures and bake safe?  Yes, it is when it is made with FDA-approved material. ZSR Group has rich experience in producing Custom silicone products with FDA or LFGB-approved standards. We have the FDA register list number 3011147430.

For now, you may need to know: How to choose a good silicone products manufacturer?

The custom silicone products industry belt is the first choice.

Currently, silicone manufacturers are mainly concentrated in the three major cities of Shenzhen, Dongguan, and Huizhou in Guangdong. ZSR Group is in Dongguan area.

Secondly, professional technology and rich experience can make you take a lot of detours when customizing silicone products. Facing the custom category Silicone products test whether a silicone product factory can take on this role and whether it can independently manufacture silicone mass production tooling becomes one of the audit criteria.

The quality of a silicone tooling’s determines the dimensional accuracy of the silicone product and the efficiency of manual edge removal.

Thirdly, for the silicone products price, don’t blindly choose suppliers based on price. It is recommended to choose based on the customization experience of silicone manufacturers. You must know that you pay for a penny. The cheap price brings you not a discount, but low-quality silicone products and Poor after-sale service; of course, the smaller the quantity of customized silicone products, the higher the price, the higher the price.

The customized silicone products mainly account for the bulk of labor costs.

Finally, the company’s size, personnel, equipment, and supporting silk screen spraying oil drops Surface technology such as glue is also one of the exquisite items.
