Silica gel has the characteristics of safety, non-toxicity, stable chemical properties, insolubility in water and any solvent, soft texture, high temperature resistance and so on, and is widely used in infant products, drinking water equipment, medical supplies and so on.
Abs is a * * polymer of acrylonitrile, butadiene and styrene, that is to say, it combines the characteristics of these three, belongs to environmental protection plastic, is relatively hard, has the characteristics of impact resistance, heat resistance and low temperature resistance, and is often used in furniture, sports, daily necessities, sports equipment and so on.
Generally speaking, abs and silica gel are relatively safe and can be chosen with confidence. However, like baby gutta-percha, it is generally made of silicone; And our daily common mobile phone cases and display cabinets are generally made of abs.
Is pvc silicone? What's the difference between silicone and pvc?
Parents must carefully choose baby feeding products and pay attention to the choice of materials. There are many materials for baby feeding products, and the most popular one is silicone products, which are generally made into pacifiers and are very popular with mothers. Many friends think that pvc is silica gel, while others think that pvc is different from silica gel. What is the truth? So pvc is silicone? What's the difference between silicone and pvc? Let's answer this question in detail.
Pvc is not silicone, it belongs to different materials. The differences between silicone and pvc are as follows:
1, the material is different, the material of pvc is mainly pvc powder, that is, polyvinyl chloride, as well as oil and color paste, which is heated and cooled; Silica gel is made of silica gel raw materials and some chemical elements such as masterbatch through a rubber mixer.
2, the appearance is different, pvc products have rough workmanship, while silicone products have smooth workmanship.
3, feel different, pvc toughness is small, relatively hard. Silicone products feel soft and have good toughness and elasticity.
4. There are two kinds of materials: pvc, which can be divided into ordinary materials and environmental protection materials. Silica gel is rohs certified and belongs to environmental protection materials.
5, different colors, pvc products are made of solid color, while silicone is transparent color.
It is suggested that mothers should try to choose regular brand products when choosing silicone products for their babies, so that the quality of the products can be guaranteed and they can be safely used by their babies.
Which is more durable, better material and toxic, pvc or silicone?
When the baby is born, it drinks milk. When the baby grows up slowly, parents can add complementary food to the baby after six months. From this time on, parents can consider buying tableware for their baby. Of course, there are many kinds of baby tableware materials, and the common ones are pvc materials and silicone materials. For some novice parents, they don't know these materials and don't know which one to choose. So which is more durable, better material and toxic, pvc or silicone? Let's answer this question in detail.
Silica gel is more durable than pvc, because silica gel is more elastic and has better heat and cold resistance than pvc. Silica gel can be heated in microwave oven, but pvc can't. In terms of material, silicone is better, because silicone itself is an environmentally friendly material, while pvc is a plastic material, not an environmentally friendly material.
Pvc and silica gel are non-toxic. Pvc is polyvinyl chloride, which is a common plastic material. If plasticizers and antioxidants need to be added in the production process, these auxiliary materials are toxic. Therefore, pvc products should be produced by regular manufacturers, so that the added accessories meet the standards, and there is no problem. Silica gel itself has good biocompatibility and is non-irritating, non-toxic and non-allergic.
However, parents are advised to choose silicone tableware for their baby, which is safe and stable, and it is not easy to have problems during use.
Which is safer, silica gel or pe?
It's not easy for moms to choose a bottle for their babies. A treasure mother will look at the appearance, and a good-looking bottle will attract the baby's attention; Bauer's mothers will look at the safety of the materials because it is related to the baby's health. So as far as silicone bottles and PE bottles are concerned, which is safer?
At present, there are many kinds of baby bottles on the market, such as glass, silicone, pe and so on. As far as pe and silica gel are concerned, their differences are mainly as follows:
1 price. In terms of price, the price of silica gel bottles is relatively high, and its cost is relatively high; Pe material will be cheaper, so the price of bottles made of this material will be lower than that of silicone bottles.
2. Safety. Both pe and silica gel can withstand high temperatures, but relatively speaking, silica gel can withstand higher temperatures, so the safety of silica gel bottles at high temperatures is higher, while pe will be weaker.
3. Transparency. In this respect, pe is better than silicone bottles.
4. cleaning. As far as cleanliness is concerned, it is also a concern of treasure moms. The two kinds of bottles are relatively better washed with pe, and the silicone bottles are more likely to leave stains.
Generally speaking, silicone bottles are safer in this respect, because mothers will boil and disinfect at high temperature. Mothers, you can consider buying a silicone bottle, but pay attention to cleaning it in time before and after use.
