Common Silicone Curing Problems & Solutions
During silicone manufacturing, improper curing conditions or incorrect vulcanizing agent dosage can lead to product defects. Understanding these issues helps manufacturers maintain consistent product quality and production efficiency.
| Problem | Possible Cause | Recommended Solution |
|---|---|---|
| Sticky or under-cured silicone | Insufficient vulcanizing agent dosage | Increase peroxide dosage within recommended range |
| Surface bubbles or voids | Moisture contamination or trapped air | Improve mixing process and reduce moisture |
| Yellowing after curing | Excessive curing temperature or incompatible additives | Optimize temperature and compound formulation |
| Poor mechanical strength | Incomplete crosslinking | Increase curing time or adjust curing temperature |
| High compression set | Improper vulcanization conditions | Improve crosslink density through optimized curing |
Production Tip
Maintaining precise curing temperature control and correct peroxide dosage is essential for achieving optimal silicone performance. Many manufacturers conduct small-scale trial runs before full production to determine the best formulation parameters.
