Under normal circumstances, the standard transparent silica gel products will not be yellow for a few years, but there are some transparent silica gel products that just come out of the oven look yellow, what is the reason why the products just come out of the oven become yellow?

From a non-professional perspective, there are three aspects:

(1)  curing agent selection;
(2)  Process formula and production process;
(3)  The quality of silica gel raw material itself is too poor.


From these three aspects, we can explain why some silicone tubes on the market are cheap, and some silicone rubber tubes are expensive. There are a lot of demanders only pursue cheap, a phone call only care about the price, but never care about the quality. So sorry, if you just want to look for cheap silicone rubber pipe products, then the roadside rubber store, you can always buy.
