In order to meet the development requirements of silicone products, the requirements of green, safety and environmental protection standards are getting higher and higher, what FDA testing silicone products must pass and some ROSH reports to prove and so on.
Now on the market ordinary silica gel and platinum silica gel believe that we are no stranger, so how do we distinguish between ordinary silica gel products and platinum silicone products these two products?
Distinguish from the molding process: ordinary silica gel and platinum silica gel are prepared by different catalysts, in fact, in addition to ordinary silica gel, platinum silica gel, there are medical grade and food grade silica gel.
This is also a grade, of course, the highest level is medical-grade silicone and food-grade silicone.
Ordinary silica gel products are made of ordinary silica gel raw materials using the most traditional curing agent, although the products are non-toxic, odorless and other aspects of excellent performance; but ordinary silica gel products have a fatal disadvantage is the growth over time.
If the product is not maintained, ordinary silica gel will yellowing or dark lines.
On the other hand, platinum and food-grade silicone products will not have such a problem: the performance of imported silicone raw materials and two-component addition curing machine is much better than that of ordinary silicone gel in all aspects. for example, in the case of long-term use, it will not yellowing or dark lines and other phenomena.
Distinguish from the scope of application: ordinary silicone is most commonly used in environmentally friendly industrial supplies, accessories and auto parts, electrical accessories; platinum silicone, medical grade and food grade silica gel are widely used in medical and health products, daily necessities (such as silicone kitchenware, silicone gifts, etc.), such as higher safety and environmental protection industries.
Distinguish from the surface and performance: ordinary silica gel can not achieve those performance effects mentioned in the market, for example, the long-term use of the temperature range of-40 °to 280 °will not yellowing and degradation; the general ordinary silica gel will not do very well in the vulcanization process considering the time and processing cost of silicone products, so ordinary silica gel has a great smell.
At the same time, the surface is opaque and dusty. In a word, ordinary silica gel is far from being able to achieve the performance of products made of platinum and food-grade silica gel.
