Gap filling materials need specific physical properties to provide consistent sealing in application.

Gap fillers need to be flexible, have low compression set and be stable under environmental variances, to compensate for design discrepancies and engineering tolerances. kSil® silicone sponge grades are ideal for gap filling materials in a range of applications due to its low compression set, flexibility and high performance at temperature variations from -60°C to 230°C (-76°F to 446°F).

Gap filling for aerospace

kSil® V-0 silicone sponge and rubber can be used to provide gap filling in both commercial and private aircraft. Providing a consistent level of performance at extreme temperatures, low compression set, flame resistance to UL94V0 and Federal Aviation Regulations (FAR 25) as well as holding OEM specifications such as Airbus ABD0031, kSil®V-0 improves fire and passenger safety. Typical applications include door, wall and roof panels, lighting units and electrical enclosures


Gap filling for automotive

kSil® silicone sponge is commonly used for many applications within vehicle production, including gap filling. Protecting against water, dust, noise, shock and vibrations, kSil® sponge gap fillers can be found throughout the vehicle, including in HVAC systems, engine parts, fuel systems, door and roof panels, plus many more..

Silicone gap fillers are also found in Hybrid and Electric Vehicles where they are needed to seal and protect the battery unit through its numerous charging cycles.


Gap filling for HVAC

kSil® silicone sponge is widely used in HVAC systems across sectors such as Aerospace, Automotive, Construction and Rail. Being temperature and flame resistant, kSil® is the ideal material for HVAC gap filling. Gap fillers also act to reduce vibration and rattle as well as sealing the HVAC unit from water, dust and moisture to reduce the likelihood of failure.
