Some suggestion to use the ultra high pressure washer hose
The smell of rubber products is accustomed to, but the problem of odor in silica gel is a concern of many people. Because silica gel is a non-toxic and environmentally friendly material, it should be odorless. However, some silicone daily necessities are odorous when used. What is the cause of this phenomenon? Is there any harm to people in the presence of odor? As a professional manufacturer, I will explain the cause of the smell of silicone products and whether it is harmful.
The raw materials of silica gel are generally divided into silicone oil, silicone resin and white carbon black. At the same time as the solid rubber is refined, a reinforcing agent is needed, and the solid coagulant is mixed to become a semi-transparent solid raw material, and the coloring rubber and the vulcanizing agent are added. Mixing into a moldable material, which is molded at a high temperature of 200 degrees at the end! It is inevitable that after a lot of mixing and fusion, the scent of the finished product will be cured. However, the problem of odor in silicone products can be solved by the manufacturer using secondary vulcanization. The odor and the residual components in the product are removed to keep the product environmentally friendly and non-toxic. Therefore, the odorous silicone products may not have been subjected to secondary vulcanization. And after a long time of sealing, it causes odor. However, the odor will slowly disappear after a few days of ventilation.
All in all, the silicone products with odor can be used with confidence, and experiments have shown that odor silicone products will not cause harm to the human body. Because silica gel always retains its original performance, it is non-toxic and environmentally friendly.
