How to distinguish ordinary silicone and food-grade silicone products?

The silicone can be divided into ordinary silicone and food-Grade silicone. Usually, ordinary silicone was widely in accessories for machinery, electronics, automobiles and agro-industrial industries.

The main purpose of Food-grade silicone is used for the manufacturing of food-contact products. Food-grade silicone is a type of silicone that is safe for use with foods. Silicone is used frequently in making molds to use for food that begins as liquids and solidifies. 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.

Food-grade silicone is widely used in silicone kitchen utensils, baby pacifiers, drinking cups, baby sippy cups, and other places. Since food-grade silicone is higher in quality and price than ordinary silicone, the cost of producing regular qualified silicone products will be much higher. It is for this reason that some unscrupulous manufacturers use ordinary silicone to produce water cups, kitchen utensils, baby pacifiers, etc., which are in contact with our diet in order to reduce production costs and are shoddy.

Such products not only fail to meet the requirements of quality but also endanger the health of our human body. So how do we tell which ones are ordinary silicone and which ones are food-grade silicone?

The best way is to test on the lab by Intertek or Bureau Veritas or SGS, TUV. So most of the brands for the food contact brand products have certification about their goods.

As a Manufacturing company, we would like to share some easy ways to distinguish them.

Smell Difference

Ordinary silicone products have a big smell.

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

The LSR silicone rubber smell is better than solid silicone rubber.

Touching Difference

Food-grade silicone has very good toughness and elasticity. It is not easy to be permanently deformed by the action of external force, and the hand feel will be smoother, while ordinary silicone products are easily deformed and rough to the touch.

Pinch or Twist test

When you pull hard, pinch or twist the products. The FDA products and ordinary silicone products will change colors.
