What is Food Grade Silicone?

Food-grade silicone is a kind of inorganic polymer colloidal material formed by the condensation of silicic acid, which is a kind of environmental protection silica gel.

Why Use Food Grade Silicone?

While comparing to rubber and other materials, food-grade silicone rubber offers many advantages depending on daily use. Advantages can include: 

  • Durability

  • Heat and Cold resistance

  • Bacterial and Chemical resistance

Here we mention some of its characteristics:

  • Food-grade materials are very resistant to damage and degradation from extreme temperatures.

  • Manufacturers without petroleum-based chemicals.

  • Food-grade silicone rubber is safe and easy to store food, and put in the microwave, freezer, oven, and dishwasher.

  • Made from an abundant natural resource, lightweight, and easy to carry and transport.

  • Non-toxic material and odorless that contains no BPA, latex, or phthalates

  • Food-grade silicone is considered non-hazardous waste, and it may get recycled at selected locations.

Food-Grade Silicone Rubber Vs. Medical-Grade Silicone Rubber

In contrast, medical silicone rubber is the most used synthetic rubber of all synthetic elastomers in permanently implanted sub-dermal products. Medical-grade silicone, which is verified for biocompatibility, is a popular material for various items.
