With the constant improvement of silicone products process, making the silicone products is becoming more and more widely used in our daily life, but some businesses in purchasing silicone products to find some silicone products have a very pungent odor, then can produce “why smell? Safe?” And so on question?
Vulcanizing agent is a kind of promote a catalyst, silicone raw materials vulcanization molding will evaporate after molding silicone products, only a few remaining, after 48 hours will evaporate. Vulcanizing machine won’t product harm to human body, these problems are mainly some silicone manufacturers in order to save costs, use is not environmental protection, low prices of ordinary vulcanizing agent, rather than completely can pass ROHS testing environmental tasteless vulcanizator, but low sulfide opportunity to produce a pungent smell of burning, volatile time in a month or so, so in choosing a silicone gifts, products try to choose better tasteless silicone products. Especially the silicone kitchen utensils and appliances, more strict requirements guests.
Silicone rubber basically is not exist a lot of taste, smell problem is mainly the vulcanizing agent and vulcanizing machine mentioned above, in principle, the selection of vulcanizing agent should choose tasteless vulcanizator, 2 basically has no smell. Note is secondary vulcanization temperature from 200 degrees when miss / 2 to 4, also can be 155 degrees or 150 degrees / 12 hours. So the smell of the silica gel and water molecules will evaporate, no smell.
