Formed food grade liquid silica gel is composed of A component and B component, B component contains platinum catalyst.Platinum catalyst is an environmentally friendly, non-toxic and odorless material that does no harm to the human body.Add molding food grade liquid silica gel is by environmental temperature to cure, when the indoor environment temperature is higher, silica gel curing speed is faster;When the indoor ambient temperature is lower, the curing speed of silica gel is slower.So what is the testing standard for food-grade silica gel?

  Food grade silica gel and molding liquid silica gel performance detection, mainly according to the following parameters to judge, including hardness, viscosity, tear strength, tensile strength and elongation.Food grade liquid silica gel hardness from Shore A0 degrees to 60 degrees, the middle every 5 degrees a unit.Add molding food grade silica gel viscosity is generally below 10,000 CPS, with the higher the hardness of silica gel, its viscosity will increase.

  Tear resistance and other properties are also changed with the change of hardness parameters, the general rule is that the higher the hardness, the performance of silica gel will be worse;Anyway, the lower the hardness, the performance of silica gel will be worse.Hardness in the range of 20-30 degrees, the performance strength of silicone molding is suitable.

  Add molding liquid silica gel in environmental performance testing, there are many standards, methods are not the same.First of all, we need to see whether the food grade silica gel has a pungent taste, and the pungent smell is industrial grade liquid silica gel.The second is to look at the ratio of silica gel, the ratio of molding silica gel is mostly 1:1 or 10:1 ratio, the ratio of industrial grade silica gel is mostly 100:2.Z is to see whether the silicone molding is easy to produce toxic reaction, mainly food grade silica gel and heavy metal toxic and harmful element material contact, will lead to molding liquid silica gel poisoning is not solidified.

  The above is one of the food grade silica gel inspection standards. Different performance testing standards are not the same. If you want to obtain more testing standards, please pay attention to our new best.
