Food grade silica gel material is a two-component room temperature curing liquid rubber silica gel, with good activity, fast curing, more safe and environmental protection, can fully meet the requirements of food grade.What are its features and what matters need to be paid attention to in the process of production and use?The following macro silica gel to give you a detailed description.

  A, food grade silica gel material characteristics:

  Food grade silica gel has excellent resilience, yellowing resistance, thermal stability, transparency, tear strength, heat aging and weather resistance, and moderate viscosity, easy to operate, high transparency of products, can see whether there are bubbles and other defects in the casting material in the mold, line shrinkage rate ≤0.1%, copy the size of precision products.

  Three, the use of food silicone raw materials:

  1, when using, it is necessary to make food grade silica gel raw materials fully exposed to air.The larger the contact area, the faster the solidification, on the contrary, it becomes slower, or even not curing.The thicker the rubber layer, the longer the curing time, the higher the humidity and temperature in the same environment, the faster the curing speed of the rubber layer.Vice versa.

  2. This edible grade silica gel raw material product is a non-dangerous chemical, which can be stored and transported in accordance with non-dangerous goods. When used, it is not toxic and polluting to the human body and the environment, so there is no need to take too many preventive measures.

  3, products in storage and transportation, should be kept dry, prevent sun and rain.Effective storage period of 12 months, more than the storage period, after inspection qualified, can still be used. After the product is used, the hose should be closed immediately and can be reserved for use again.

  4. First clean the parts to be coated with glue to remove the oil stains on the surface, and then apply the product on the surface of the components after extruding from the silicone raw material hose. The glue contacts the water in the air, and then gradually solidifies into elastomers from the outside to the inside.

  In the use of food-grade silica gel to make silica gel molds, we need to pay attention to the above matters, only in accordance with the process of operation and pay attention to the precautions in the production process, the production of silica gel products can pass the quality test, without delay in the production schedule.
