Hongqiang flame retardant adhesive teaches you how to identify whether silica gel is environmentally friendly?
      [1] the general materials of adult products include silica gel, TPR and PVC. The advantages and disadvantages of these three materials are silica gel, which is environmentally friendly and absolutely non irritating to the skin
      1) high efficiency of die hot pressing,
      2) casting can reflect details and even pores,
The disadvantage of silica gel 1 is the high price of raw materials
      1) mould hot pressing, raw material is about 30 per kilogram,
      2) for casting molding, the domestic technology of raw materials is not mature, and the imported materials are about 400 per kilogram (at present, the materials we produce are comparable to the imported materials, and the price is only half of the imported materials, but the production capacity is still relatively low)
The disadvantage 2 of silica gel is,
      1) there are shape and size restrictions on the hot pressing of molds. There are ribs on the surface or details that cannot be reflected. There will be obvious parting lines on the curved ones. Generally, manufacturers will polish them, but they will omit them in order to save costs. They can't see them in the pictures of online stores and don't care about the products received. The advantage of TPR is environmental protection, the price of raw materials is low, and it can be made into large parts. The disadvantage is that the details are not reflected enough,
PVC, this material has the advantages of very low price and the disadvantages of toxic, carcinogenic and flame retardant adhesive.      2) After making such a comparison, we can understand which material is good, which material is poor and which is toxic. Next, I can introduce how to distinguish these three materials. We can also find that many adult products almost avoid materials, and those using silica gel will focus on them
     3) we can take the non key parts of the product and burn them with a lighter. Silica gel is difficult to burn. The ash after combustion is gray. TPR combustion is very similar to candles. There is no ash after combustion and it will melt. PVC is easy to burn and black tar after combustion
     4) in addition, many adult products now carry the banner of real-life mold inversion. In fact, as long as the material is TPR, it is almost meaningless. If you want to perfectly reflect real people, only silicone casting can be done. For example, you can turn over a silicone finger and cheat the fingerprint attendance machine. Nowadays, the real person inverted mold is generally made by foreigners using silica gel to take the mold on the real person, then inject wax, and then take the wax sample to open the mold for production in China. In fact, the opened iron mold may not be like the wax sample at all, so many domestic manufacturers simply open a mold by imagination, and then say it belongs to a star, and even someone can open the mold by telling a photo.
