The story:
A contract manufacturer making Transformers for HVAC had issues related to too rigid of an epoxy system, so as parts heated up, components would pop off and the PBA would crack. Krayden partnered with ITW to delivered the Insulgel 70 cc FRNS, because it has a high CTE so it can expand as the components expand. Because it’s a gel instead of a rigid solid, parts can have more flexibility, creating fewer reworks, less repairs, and less defects
| What is the application? | Potting transformers |
| What issues was the end user having? | The customer was using a rigid epoxy system with low CTE. As the parts heated up, components would pop off and the PBA would crack. |
| What material was used to solve the issue? | Insulgel 70 cc FRNS |
| Why was the material chosen for the application? |
Better CTE, less rigid, better crack resistant, easier to mix |
| Why did this material work better than other materials? | Insulgel 70 cc has a high CTE so it can expand as the components expand. Additionally, it is a gel instead of a rigid solid, giving parts slightly more flexibility. |
| Did the material improve the process? | Yes |
| If So, how? | Less rework, less repair, fewer defects |
| What industry/market was this material used in? | Contract Manufacturer making Transformers for HVAC |
