What are the causes of silicone products surface projections?
Silicon rubber products company colleagues asked, they have several products after stripping surface uplift at the bottom of a 10*10 mm nodules, and basically fixed in certain cavity. Although we are increasing the exhaust groove die, but still can not eliminate the phenomenon of long tumour.
The reasons for this phenomenon are mainly the following three points:
1. The less sulfur, curing time is not enough
2. Rubber processing is not enough, the back glue try
3. If the product is not the skeleton and the skeleton impurities gum, or coated drug problem.
