Silicone Foam Packing
−50°C to +200°C
Main applications
silicone foam packing that achieves zero leakage
Key Features
Excellent sealing performance
The elasticity characteristic of silicone foam fits tightly into flange, door and cover gaps, blocking gas, liquid and dust leakage
−50°C to +200°C
Usable from hot steam to cryogenic piping — no hardening or cracking through temperature change
Chemical and ozone resistance
The chemical resistance characteristic of silicone — durable long term against acids, alkalis, ozone and UV
Easy to work on site
Supplied as silicone foam sheet or roll — cut and shaped on site and applied to any geometry
Repeated compression and recovery
Fully recovers after compression — no loss of sealing over long repeated service, dramatically extending replacement intervals
