What is Silicone?
Silicone is a synthetic polymer made from silicon (Si), oxygen, carbon, and hydrogen. It has a rubber-like texture, making it flexible, durable, and resistant to heat and moisture. The process of making silicone starts with silicon, a natural element found in sand and quartz.
Through a refining process, silicon is extracted and combined with oxygen to form silica, which is then processed into siloxanes—the building blocks of silicone. To turn siloxanes into a usable material, manufacturers add curing agents that determine the final properties of the silicone.
Unlike plastic, silicone does not easily degrade under high temperatures and is often considered a safer alternative for food storage and kitchenware.
Key Properties of Silicone:
- Heat-resistant – Can withstand high and low temperatures without breaking down.
- Flexible & Durable – Stretches and bends without cracking.
- Waterproof & Non-reactive – Does not absorb moisture or react with food.
- Resistant to Chemicals & UV Rays – Long-lasting and stable over time.
Silicone is used in a variety of industries, including kitchenware, medical equipment, electronics, construction, and automotive applications. However, not all silicone is the same—its quality and safety depend on how it’s processed and cured.
What is Regular Silicone?
Regular silicone, also known as industrial-grade silicone, is a general-purpose material used in non-food applications. It is commonly found in automotive parts, construction sealants, and electrical insulation. Unlike food-grade silicone, regular silicone may contain fillers, plasticizers, or byproducts that make it cheaper to produce but potentially unsafe for direct food contact.
Since it is not regulated for use with food, it may release volatile organic compounds when heated, which could pose a health risk. Because of this, regular silicone should never be used for cooking, food storage, or baby products.
Regular silicone, also called industrial-grade silicone, is used in non-food applications like:
- Automotive parts
- Electronics
- Construction sealants
- Medical equipment
Why Regular Silicone May Not Be Safe for Food Use:
- May contain fillers like chalk, plasticizers, or other additives.
- Not tested for food safety, meaning it could leach chemicals when heated.
- Might release volatile organic compounds (VOCs) when exposed to high temperatures.
For safety, regular silicone should never be used for cooking, food storage, or baby products.
What is Food-Grade Silicone?
Food-grade silicone is a purified version of silicone that is specifically designed for safe contact with food and beverages. This type of silicone is typically cured with peroxide, which may leave behind small amounts of chemical residues.
It must meet strict safety standards set by regulatory agencies such as the FDA in the United States and LFGB in Europe. Contrary to industrial-grade silicone, food-grade silicone does not contain harmful fillers or plasticizers that can leach into food.
It is also highly resistant to heat, meaning it won’t break down or release toxic chemicals when exposed to high temperatures. This makes it an excellent choice for bakeware, food storage containers, baby products, and kitchen utensils.
Key Features of Food-Grade Silicone:
- Free from BPA, phthalates, and other toxic chemicals found in plastic.
- Non-reactive – Won’t leach harmful substances into food.
