What Is FDA Food Grade Silicone?

Food-grade silicone rubber refers to products made from food-grade silicone materials that can come into direct contact with food. Silicone materials themselves cannot be eaten directly, they serve as a material for various applications. Their simple chemical structure makes them more stable and environmentally friendly. They are widely used in manufacturing kitchen tools, children’s toys, cake molds, ice molds, and various accessories for food machinery.

What Is FDA Food Grade Silicone

FDA Food Grade Silicone Made Up Of?

FDA silicone material is a polymer synthesized from natural stone, with its main component being silica, the primary material used in glass manufacturing.

95% of food-grade silicone material is composed of stone, a natural material that fully complies with silicone fda approved, ensuring safe contact with food. In the product design process, more and more components are opting for silicone material replacements. With the passage of time, as demands on products increase, the choice of silicone material will become more common.

Food Grade Silicone vs Silicone

Food Grade Silicone vs Silicone

Material Difference:

  • Both food-grade silicone and regular silicone are primarily composed of silicon dioxide. The main difference lies in the proportion of silicon dioxide content in the material itself.

Stretching Difference:

  • In food-grade silicone, the proportion of silicon dioxide is higher, and the material does not turn white during stretching.
  • In regular silicone, the proportion of silicon dioxide is relatively lower compared to food-grade silicone, and the product may turn white during stretching tests.

Odor Difference:

  • Food-grade silicone adopts a platinum-cured process and is virtually odorless.
  • Regular silicone uses a process involving Double 2,4 vulcanizing agent, which may result in an odor.
  • During the comparison process, the focus is generally on these three differences: material, stretching, and odor. The odor mainly comes from the vulcanizing agent, and different vulcanizing agents may have cost differences.

Uses Of Food-Grade Silicone Include:

Uses Of Food-Grade Silicone

  • Food-grade O-rings
  • Food-grade peristaltic tubing
  • Milk tubing
  • Coffee cups
  • Children’s teething toys
  • Food machinery conduits
  • Cake molds
  • Candy molds
  • Scrapers
  • Spoons
  • Brushes
  • Food-grade silicone gasket

Can Silicone Be Recycled?

Can be recycled, but can not be used twice, silicone is the characteristics of thermosetting materials, and recovered silicone materials can only be used to extract silicone oil.

Silicone oil has a high added value and is used in many industries, so the recycling of silicone waste is not something to worry about.—–Most plastic cannot be recycled

Is Silicone Safe For Food?

Food grade silicone material is safe and can be used with confidence in any product that comes into contact with the kitchen, baby and food.

Is Silicone Bpa-Free?

Silicone materials do not contain BPA, and the food grade silicone materials we use are certified to be BPA-free

Is Silicone Better Than Plastic For The Environment?

Yes, silicone rubber is more environmentally friendly than plastic materials, plastic materials will melt volatile harmful gases at high temperatures, silicone temperature can reach more than 200°C, after burning is a white powder, similar to lime powder.

Why is Silicone Expensive?

The relative cost of silicone compared to other elastomeric materials is higher due to several factors affecting its base material, manufacturing process, material performance, compliance with food standards, and consumer demand.

The main reasons for its higher cost include:

  1. Raw material and production time: Silicone is primarily composed of silicon, carbon, hydrogen, and oxygen, forming a unique elastomeric polymer. The manufacturing process for silicone is relatively lengthy compared to other elastomeric materials.
  2. Complexity of manufacturing process: Silicone rubber production involves multiple complex steps, including material mixing, hydrolysis, precipitation storage, washing, filtration, concentration, condensation, solvent extraction, and high-speed separation. This process requires significant equipment, labor, and research and development investment.
  3. Material performance: Silicone rubber exhibits excellent elasticity, high-temperature resistance, and chemical stability, making it highly customizable.
  4. Compliance with standards: Silicone materials must meet strict standards such as FDA and LFGB certification. High-quality materials require more rigorous production processes and precision equipment, contributing to higher costs.
  5. Consumer demand: Increasing consumer expectations for product quality, especially in the food, children’s toys, medical, and consumer sectors, drive demand for environmentally friendly materials like silicone rubber. Manufacturers invest more in research and development for silicone rubber materials to meet consumer demands, leading to improved quality.

Does Silicone Contain Rubber?

Both silicone and rubber have a similar soft texture when touched. Although the tactile sensation of these two materials is similar, they have significant differences in cost. For instance, rubber is primarily derived from latex produced by rubber trees, while silicone is mainly composed of silicon, carbon, hydrogen, and oxygen. Despite their similar tactile feel, silicone does not contain rubber components.

How Many Degrees Can Silicone Withstand?

Silicone’s temperature range is highly adjustable. It can be customized to withstand temperatures as high as 300°C and as low as -100°C. Typically, the general-purpose material temperature range is between -30°C and +220°C. So, depending on your specific usage environment, you can choose between customized or general-purpose materials to match your equipment.
