Parents attach great importance to the health and safety of infant care products. In terms of material and practicality, silicone bibs for children have become the first choice for many infants. Pure silicone collagen materials are environmentally friendly, non-toxic and tasteless. However, silicone products may have different tastes after silk screen printing, hand oil spraying, YM process, IMD process, Leidiao, glue dripping, water sticker and other processes. This is very prominent on the silicone bib. It can be seen that the generation of odor is most likely to occur in various processes after molding.
Usually, the process that causes silicone bibs to smell and produce pungent smell is: silk screen printing and hand oil spraying. The silk screen printing ink may have an irritating taste because it is composed of different chemicals. After the silk screen printing is completed, the silicone phone case will have an obvious taste. However, it is not common for the silicone phone case to smell due to silk screen. These are also normal phenomena. After two or three days of natural ventilation, the smell will naturally disappear.
Moreover, after these processes, it is necessary to pass through the tunnel oven for high-temperature secondary vulcanization. The purpose of this is not only to remove the taste, but also to volatilize and disperse the residual harmful substances of the materials as much as possible, so as to finally form a good product inspection and delivery. However, some silica gel bib factories are opportunistic, using inferior silica gel raw materials or excipients, or the production process is not perfect, so that the products produced are seriously substandard. The regular silica gel factory adopts food grade silica gel material, which is much higher than the ordinary silica gel phone case in terms of raw materials and production process. After forming, it needs enough time to remove volatile substances.
Some manufacturers ignore this problem in pursuit of efficiency and cost reduction, resulting in the final production of mobile phone cases that do not meet environmental standards. Generally, the manufacturers producing such products are relatively small. Therefore, Xinfanshun Silicone Xiaobian told us that we should pay more attention when purchasing silicone products. Silicone products with serious smell cannot be purchased. Silicone products with good quality only have very slight smell, which can be automatically eliminated after a period of time. In addition, silicone products with good quality will be very flexible and comfortable to the touch, and have excellent hand feel and texture.
