DyBond® Flexible insulation pre-pregs
The Coveme DyBond® pre-pregs products are flexible insulating materials having a B-Stage (semi polymerized) resin on one or both sides. The coating with the resin can be on the full surface or it can have a diamond pattern of the same thermal class than the support. DyBond® is used as electrical insulator in dry and oil transformers as well as some types of rotating machines.
The product range includes materials produced using several substrates such as:
- Nomex® brand paper
- DyTerm®: flexible laminates of Nomex® paper and polyester film
- DyTerm® K:flexible laminates of Nomex® paper and Kapton® polyimide film
- DyFlex®: flexible laminates of non woven and polyester film
- Kemafoil® HBB: surface treated polyester film
DyBond® products are available in rolls of 100~200 m length, with ID 76 mm and a workable width of 900 mm. The portion of surface coated with resin in the diamond patterned version is around 40%. DyBond® products have a shelf life of 6 months at room temperature (max 23°C) and up to one year if stored in refrigerated cells (max. 5°C).
