The label of food grade silicone is that it is non-toxic, odorless, and in liquid form. It is composed of two components, A and B, in a 1:1 ratio. Component A is a platinum vulcanizing agent, and component B is silicone. They need to be mixed together to become solid. Generally, food grade silicone has relevant certificates such as RoSH, SGS, Reach, and MSDS to confirm its safety.
It has a hardness range from 0 degrees to 40 degrees, and different hardness can be used to make different molds. From 0 degrees to 0 degrees, it can be used to make silicone gel for the human body. From 5 degrees to 15 degrees, it can be used to make molds for candle fragrances, chocolate, and jelly. From 15 degrees to 30 degrees, it can be used to make products with high texture requirements.
It is very similar to its sibling industrial grade silicone, which is also a condensation type silicone. It has a pungent odor because its curing agent is organotin. A simple way to distinguish Z is to distinguish their odors.
In fact, it can also change color through color matching. We just need to purchase a small amount of color paste from the market and add it in.
