Gap Pad VOUS die-cut custom parts
Thermal materials normally work better under pressure. However, some assemblies do not have the luxury of pressure because of sensitive components. For that reason, in thermal gap filling materials, soft seems like it can’t be soft enough sometimes. However, with Bergquist’s Gap Pad VO Ultra Soft, ultra is about as soft as it gets at a measurement of 5 on the Shore 00 rating scale.
Why use Gap Pad VOUS aka GAP PAD TGP 1000VOUS?
Gap Pad VOUS is topped with a fiberglass reinforced Sil-Pad (its Sil-Pad 900s) that offers electrical isolation. At 1 W/m-K this gap filling pad may not be the most thermally conductive, but it makes up for it in its conformability. The fiberglass reinforcement is great for puncture resistance during assembly when sharp objects may be present. Similar to many of Henkel’s Bergquist Gap Pad materials, Gap Pad VOUS is UL 94 V0 rated. The temperature range is impressive at a continuous working temperature of -76°F – 392°F. This ultra-conformable, soft product is used in many applications for its ability to easily fill gaps where the luxury of mechanical stress is not available. Some of these applications include telecommunications, power generation, or applications that may require heat being transferred towards a heat-spreader. Given GPVOUS properties, its versatility is nearly limitless for use in different applications of low stress. At times, given its high conformability, it’s used for vibration dampening and its shock absorbing abilities.
Gap Pad TGP 800VOS, versus Gap Pad TGP 1000VOUS?
We know they look very similiar, and you may be tempted to think they are the same. They are different materials. However, one thing I wanted to say on this, NEDC suggests Gap Pad VOUS in nearly every situation. This material is ultra-compliant, and is much more widely used, and utilized for general gap filling applications where good performance is required. Gap Pad VOS has slightly worse performance.
Do I remove Gap Pad VOUS Pink Side?
NO- this is the Sil-Pad side. The Sil-Pad side is intended to be inside the application- its not for removal. However, the clear liner that is on this side when the material has “AC” can be incredibly difficult to remove depending on how big the part is. You should be ultra careful defining which side is PSA, and which side is tack in these cases. We probably get this question at least once a week, the BLUE side is the TACK side, and the PINK side is the Sil-Pad. The physical Sil-Pad should not be removed, but if it has “AC” the clear liner should be removed. For clarity:
With Gap Pad VOUS, VOS, and VO the BLUE LINER side is the TACKY SIDE. If the material has “AC” or PSA that is the PINK side.
Which Side Do I remove First is GAP PAD VOUS, VOS, VO has PSA(AC)?
The best way to do this, is to remove the clear liner first. The clear liner is the tougher one to get off (PSA side), and should be removed first, and then remove the blue diamond liner (the tack side) second.
