A huge range of NYHAGUM® two- and multi-layer composites provides our customers with the perfect choice of end plug material for any type of capacitor application.
Different NYHAGUM® material compositions, variable material thickness, a flexible layer structure and various surface coatings ensure that NYHAGUM® high-quality products meet a vast number of technical requirements.
| 1. | NYHAGUM® two-layer composite laminates |
| - | consist of a carrier material made of resin-impregnated, firmly bonded paper layers with an elastomer layer. |
| 2. | NYHAGUM® multi-layer composite laminates |
| - | identical with 1., but fitted with an additional surface coating of the paper carrier layer. This has a direct sealing function to prevent swelling of non-coated hard paper in direct contact with aggressive electrolytes. |
| - | electrolytes are commonly based on solvents such as dimethylacetamide (DMA) and dimethylformamide (DMF). |
Proper surface coating is selected with respect to chemical requirements:
| a) | polypropylene (PP) |
| b) | polytetrafluoroethylene (PTFE) |
| - | excellent swell-resistance to polar solvents such as DMA, DMF and EG as well as other aqueous media containing acids, butyrolactone, glycerine and glycol |
| - | excellent diffusion resistance |
| - | excellent ageing characteristics |
| - | excellent resistance to ozone |
| - | extremely little hardening under high longterm temperature exposure |
| - | excellent, user-friendly punching characteristics |
| - | extremely low-chloride thus highly corrosion-resistant |
NYHAGUM® meets all demands in terms of temperature, pressure, electrolyte concentration, end plug size, number and arrangement of holes, minimum expected service life, etc to the full extent.
