  Material selection  
 

Silver plated Copper (Ag/Cu) filled Form-In-Place silicone gasket
Our Ag/Cu FIP silicone designed for high shielding requirement Form-In-Place application, it is 2 components, heat curable Ag/Cu filled silicone compound. It has excellent shielding performance combined with low compression forces and good mechanical properties with outstanding compression set. Silicone rubber can easily withstand heat, cold, moisture, UV, ozone and pressure over extended periods. Operating temperatures are between -55 degree C and +125 degree C.

Nickel Graphic (Ni/Gr) filled Form-In-Place silicone gasket
Our Ni/Gr FIP silicone designed to replace high cost Ag plated particles at a fraction of the cost. The nature of the Ni plated Graphite particles not only provide reasonable electrical conductivity but also absorption property. The system offers enhanced galvanic corrosion resistance and stability in severe environments

Environmental sealing Form-In-Place silicone gasket
It is designed as a water and environmental sealed Form-In-Place gasket, It is not electrical conductive but provides extremely resilient elastic gasket with good adhesion on general plastics and metals. It is a two component, heat curable silicone system, optimized for Form-In-Place process. Short cycle due to its less than 1 hour heat curing process which meets high production rate products. No leaking of silicone oil under high temperature and pressure. Very elastic rubber property, low compression force

 
 
 
  Features  
 

- Up to 60% space saved- flanges as narrow as 0.020กจ (0.50 mm) can be gasketed.
- More than 75 dB shielding effectiveness from 200 MHz to 10 GHz with very small gasket
beads.
- Accuracy for gasket location within 0.001กจ (0.025 mm).
- More than 12 Newtons/cm2 shear adhesion to common housing substrates and coatings.
- Highly compressible gaskets, ideal with limited deflection force.
- Speed- gasketed parts typically prototyped and shipped within the same day.
- In-house FIP process makes the Repairing process fast turn around
