Product Usage：I will focus on another new material for mask production - environmental protection food grade silicone rubber, special food grade silicone rubber for masks is also called two-component silicone. It is composed of two parts: a component is silica gel, B component is silicone rubber containing curing agent; the two components are mixed in proportion of 1:1.
Mask has become a hot spot in our current hot spot. Why does it rise? It has even been heated by everyone. Including the chain events of poor material supply caused by this, we also have points in our mind. I will not make detailed explanation and Analysis on this.
Next, I will focus on another new material for mask production - environmental protection food grade silicone rubber
Description of food grade silicone rubber for masks:
Special food grade silicone rubber for masks is also called two-component silicone. It is composed of two parts: a component is silica gel, B component is silicone rubber containing curing agent; the two components are mixed in proportion of 1:1.
Use of food grade silicone rubber for masks:
Special food grade silicone for face mask making is mainly used for manufacturing silicone mask, food grade silicone products, high-grade products, etc.
Special food grade silica gel for mask features
1. It has excellent high temperature resistance, and the temperature can reach 220 ℃ to 250 ℃. (in other words, the mask made of this silica gel can be sterilized at high temperature to achieve the effect of sterilization. After sterilization, it can also be recycled. The terminal can save costs and does not pollute the environment.)
2. The material itself is non-toxic and tasteless, and has passed the FDA addition molding certification.
3. The raw materials for mask production in the market are scarce and the cost is high. Replacing with silica gel can not only relieve the pressure of mask manufacturers who can not buy raw materials, but also reduce the production cost
Operation method of food grade silicone rubber for mask
Mix component A and component B as 1:1, pour them after vacuum defoaming, cure them for 48h at room temperature, and cure them in tens of minutes at 80-120 ° C.
Special food grade silicone rubber packaging for masks
Component a 25, 200kg / barrel 25 and 200kg / barrel of component B shall be transported as non dangerous goods, with sealed storage period of 1 year at room temperature.
Storage and transportation of food grade silica gel for masks
Silicone rubber should be stored in room temperature, dry bath and sealed container. Do not contact with water to prevent deterioration. This product is transported without dangerous goods.
Precautions for food grade silicone rubber for masks
Do not contact this silicone rubber with any other condensed silicone, otherwise, it will cause curing agent poisoning, resulting in the phenomenon that silicone rubber will not cure. Water, impurity, organotin catalyst, acid, alkali and other organic matters with sulfur, phosphorus and nitrogen can affect the curing of the adhesive, and these substances cannot be mixed or contacted during use.
