When buying food-grade silicone molds, you should pay attention to the fact that truly environmentally-friendly food silicone molds are non-toxic and even tasteless, so you smell pungent. These molds are made of other materials, which will cause health problems if they are not environmentally friendly. If it is necessary to use food silica gel to make food molds, you can use HF-7509 platinum silica gel to meet your requirements.
