What is the white sheet of ice made from silicone ice cube tray? Is it toxic?

A friend met this condition in the frozen ice cube: The silicone ice cube trays were soaked in hot water for several hours and then the surface turned white. After freezing the ice cubes, the ice cubes were melted in the dish and many small white flakes were found. Feeling no feeling, pinching it up, it's gone... What are these substances? Is it toxic?

Silicone ice cube trays are made of environmentally friendly silicone raw materials and vulcanizing agents, and then put into molds at high temperature and high pressure to form a uniform mixture. General food grade molding will be put in oven for about 2 hours at high temperature (200 degrees Celsius) to remove residual sulphur components, etc., and put into boiling water to cook. If you do testing, it costs about 1,000 to 1,500 yuan. 

If you are concerned about an unsatisfactory ice tray, you can put it in boiling water for hours. There are many low-cost silicone products on the market today. They use adulterated raw materials and recommend buying famous brands. If the silicone ice cube tray mold uses non-toxic, odorless, food-grade 1:1 silicone, you can rest assured that it is food-grade environmentally-friendly. Conversely, if there is odor, consider using environmentally friendly materials.
