With the continuous improvement of silicone 3D doll technology, silicone 3D doll gifts are becoming more and more common in daily life. However, some gift companies have found that some silicone 3D doll gifts have a pungent odor when purchasing them. How does this odor come about?
The main issue is that some silicone manufacturers, in order to save costs, use non environmentally friendly and inexpensive ordinary vulcanizing agents, rather than environmentally friendly and odorless vulcanizing agents that can be completely tested by ROHS. Sulfurizing agents are a catalyst that promotes the vulcanization and molding of silicone raw materials. After the molding of Silicone Material, they will evaporate and only have a small amount of residue, which will evaporate in 48 hours. The vulcanization machine will not harm human products, but the low cost vulcanization opportunity produces a burnt and pungent smell, with a volatilization time of about a month. Therefore, when choosing silicone gifts, try to choose odorless Silicone Product Toys with better performance. Especially silicone kitchenware, the requirements are more stringent. In terms of silicone raw materials, there is basically no significant odor, and the odor problem is mainly related to the vulcanizing agent and vulcanizing machine mentioned above. In terms of the selection of vulcanizing agents, odorless vulcanizing agents should be used, and after two stages, there is basically no odor. Note that during secondary vulcanization, do not choose 200 degrees. 155 degrees or 150 degrees. Bake for 12 hours. If the temperature gets too high. The product is prone to aging. Quality cannot be guaranteed.
So when purchasing Silicone Ornaments, it is important to first check their wear resistance, elasticity, tear strength, and pay attention to odor issues. If these conditions are met, it indicates that the silicone products are of good quality. If they are not met, they should be abandoned to avoid financial losses.
