Security into focus - children's teeth On the silicone material

by:Cupidove     2020-08-11

children molar rod is very much treasure mom to the growth of infants and young children the best gift, it not only raised the child jue chewing growth also let infants for teeth has certain experience, and with the grinding products of market competition, the silicone material basic occupied market share half, many consumers will choose to use the silicone material to replace other materials, but many consumers did not understand the silicone children's tooth gel materials of these problems, what kind of material standards to meet the requirements of the use of maternal and infant supplies!

baby silicone products is usually need to meet all kinds of certification testing requirements, first the ROHS environmental protection authentication is one of the necessary threshold, and silica gel teeth that belong to the human body skin contact specification requirements, a lot of silicone rubber children's teeth are sold in the market, but some are unable to provide a higher level of inspection report, the reason it is because the products of raw materials can not meet the testing standards, so let the consumer can't subscribe.

the FDA and LFGB testing is Europe and the United States general environmental protection certification, usually by the two basic can reach environmental protection level of security certification of silicone products, and different ways of analysing materials have different deployment, HTV mixing rubber is the main type of silica gel products, rubber in different analysing it applied to materials, which are mainly composed of methyl vinyl silicone rubber, it is not only the choice of many domestic brands is food grade hot analysing in gas phase glue, and as the maternal and child supplies fully meets the requirements.

food-grade silicone rubber is also referred to as the gas phase, mainly high back tension as the main advantage, product has certain advantages and characteristics, it is compared with the ordinary glue can make high elasticity, toughness is stronger, shrinkage is bigger, better resistance to yellow silicone products, the main composition of silicon tetrachloride and air wind less income of silica and iron oxide, the hydroxyl silicone oil as auxiliary material for high temperature mixing rubber molding for raw material, high temperature after mixing moulding food grade silica gel.

from the consumer's hand silicone tooth gum material basic material from the above don't see any difference, but after long-term use of long product functionality and springback hand sensibility will have different difference, food-grade the difference between the gas phase adhesive and ordinary precipitation glue in sulfuric acid after make silica in sodium silicate deposition, fineness 300 - 400 mesh, and the second gas phase glue can reach more than 1000 mesh, the simple sense of material and silicon molecular density is higher, if you need to adhere to determine the difference of material can also be concluded through third-party certification testing.

the advantage of food grade children's tooth gel

1, than in the ordinary silica gel, the gas phase glue fineness is higher, so that can reach more than 1000 mesh; Toughness and feel more

7 mpa - 2, stretch strength can reach Between 9 mpa, silica gel products stretch not white children, and is extremely flexible, many times after the high tensile strength is still not white;

3, degree of gas phase silicone transparent to translucent, transparent, looks more luster, high and low temperature resistance, good resistance to tearing, stretching rate;

4, excellent heat resistance, ozone resistance and resistance to chemical attack; Comply with the ROHS environmental protection requirements, such as gas phase glue through the FDA certification and the European Union LFGB food standard testing.

5, non-toxic odorless, density, high tensile strength of springback is strong, can be long-term exposure to human skin, high and low temperature resistance, good aging life better and better transparency!

gas phase method of silica gel material advantage

1, used in a variety of consumer products, such as silica gel tableware, maternal and child supplies, silicone accessories, silicone daily necessities such as

2, electronic accessories, silicone environmental protection food grade packing, environmental protection silicone miscellaneous

3, across Europe and the United States, Asia, North America, such as environmental monitoring, etc.

4, long-term contact with the human body without harm, without any chemical reaction

5, higher requirements for no toxic industries, such as medical and health industry

6, higher requirements for transparency of exterior decoration

7, excellent heat resistance, ozone resistance and resistance to chemical attack

advantages and disadvantages:

of precipitated silica gel

advantages: low price of raw materials, the product has good adsorption ability, strong life is higher, conventional general environmental protection material, avirulent environmental protection, environmental adaptability is strong!

disadvantages: low density, transparent color is influenced by the environment used yellow, rebound tension is low, the material is harmless glue need to send out to taste, stretching is easy to appear white phenomenon!
