Silicone industry, there is a let a person tricky problems in liquid silicone products in use after a period of time suddenly appear white mist material appeared on the surface, and this phenomenon seems to be serious, but after wiping and erased can keep the primary colors, most will appear the phenomenon in some structure is larger, vulcanization time longer, some products in the industry of this phenomenon is called vomit frost, Spit fog. Do you see this in the liquid silicone products you buy?

Of silicone products appear white phenomenon is more, simple is the silicone products manufacturer of process error or raw materials mixing formula, caused problems in the raw material of white coating can be judged as the main reason of the silicone oil and other compounds in the process of secondary mixing conflict, such as wants to boost vulcanization time add the appropriate in the middle of the raw material inside the mold release, This phenomenon is very common release agent can improve the release rate and production efficiency, and the dose is not right will cause the product will be white!

In addition to raw material and process in the right way, the details in the process of operation will also bring white phenomenon, the product production line spraying mold release too much could lead to a spit frost phenomenon, when uneven temperature control can cause this kind of phenomenon, in addition to the silicone products aging was also to have certain factors, because the raw material performance is not outstanding, The use of the environment and temperature difference in the impact of the phenomenon of whitening frequency is higher!

For the above phenomenon, silicone rubber products manufacturers should first check the parameters of raw materials before processing, and understand which substances can be added to which substances can not be added, and then the processing conditions of all aspects of the machine need to be clear! And the main problem is to control the added material from the raw material, such as vulcanizing agent, color glue, silicone oil and so on, we must find out whether we can add and test in the deployment!
