Commonly used raw rubber for producing silicone products is divided into ordinary grade, food grade and medical grade. In addition, there is a platinum silica gel. Compared with the first three, what are the differences? What are the advantages of products produced with it?
Due to its product characteristics and advantages over ordinary silicone products, platinum silicone products are applied in industries that require high environmental protection. The main applications of platinum silicone products are: food-grade silicone tubes, medical silicone tubes, kitchenware, and adults Supplies, maternal and child supplies, etc., a large part of which is for export.
Due to the physical and chemical stability of platinum silica gel and its environmental protection characteristics, in our lives, it will gradually replace plastic and rubber and become an environmentally friendly material in the new era. Platinum silicone products are very good, so how do we distinguish platinum products from ordinary silicone products?Distinguish from the molding process:
Ordinary silica gel and platinum silica gel are prepared by using different catalysts. In fact, in addition to ordinary silica gel and platinum silica gel, there are medical grade and food grade silica gel. This is also divided into grades, of course, the other is medical grade silicone and food grade silicone. This product is processed with the most traditional silicone vulcanizing agent and has many properties such as non-toxic and odorless. But the fatal disadvantage of ordinary silicone products is that as time grows, if the products are not maintained, ordinary silicone products will yellow or darken.
Compared with food-grade silicone products, platinum silica gel uses imported silica gel raw materials and is processed by a two-component vulcanizing machine. Its performance is superior to ordinary silica gel in all aspects, such as long-term use, no yellowing or dark lines.Ordinary silica gel is most commonly used in environmentally friendly industrial products, accessories, auto parts, and electrical accessories.
Platinum silicone, medical-grade and food-grade silicone are widely used in medical and sanitary products, daily necessities (such as silicone kitchenware, silicone gifts, etc.), which require high safety and environmental protection levels.
Distinguish from surface and performance:
Ordinary silica gel cannot achieve the performance effects mentioned in the market, such as: the temperature range of -40~240° will not yellow or degrade after long-term use. Generally, ordinary silica gel does not do a good job in the vulcanization process in consideration of time and processing cost, so ordinary silica gel has a great smell. The surface is opaque and there will be sticky dust. In short, ordinary silica gel is far from the performance of platinum and food-grade silica gel.
